I just purchased a Golen 4.6 stroker for my 03 Tj. It was a bit more expensive then other options out there but their reputation, quality of build and customer service is well worth the extra cost. Plus the motor is already broke in, oil changed and everything retorqued as well as dyno tested with the video of your motor and dyno sent to you. My motor put out 383 foot pounds of torque and 278 hp. Not to shabby for a drop in motor.

I bought this motor, had all of these issues, 10,000mi in, rear main was pouring oil, also steel freeze plugs. My main issue was, when i was doing the rear main, i look up, and my cam is missing a tooth off the gear, so the cam is junk at this point, so when i tore the motor down to rebuild it, they used a re-manned head, 3 of the valves were not sealing, they used over sized valves, since the guides were so sloppy, so i had bronze guides installed. They forgot to install the cam apring and pin, so the cam was walking because of it, causing it to break a tooth off. I took the motor to my machinist, and almost all of it was complete junk. Only crate motor ive ever bought, or ever will buy again. There workmanship was absolute garbage, everything leaked. For me, its done, is what it is. If this helps one person to not buy their garbage, im happy.

This is why you taking the time to build the motor so you know it was done properly I never trust anyone

Fellow Pennsylvanian here. I dipped outta social media a good while ago. I use it for some light reading and information only. World of difference. Hope your happy in whatever you choose.

I'm finally installing mine from Chad Golen tomorrow morning..I bought it two Novembers ago and received it this past August..just haven't had the weather or health to install it..till now..(weather, not health) but I'm doing it..I have a 94 YJ that had the 2.5l 4cyl and AX5 transmission with the NP 231j transfer case..picked up the AX-15 transmission and correct spline to adapt the np231j to fit the AX-15..picked up the rebuild kit and the slip yoke eliminator kit and housing and rebuilt the entire transfer case.. So many issues between the ax5 to ax15 even though it was believed that the mounts etc were identical..(they're not...and I had to fabricate and weld the mounting bracket to fit the AX-15...I purchased the crate motor from Chad cost almost $11,000.00 just for the motor,4.0 with a 4.2 crank, Clifford intake, Holley Sniper EFI 4 barrel carb . broken in and the Dyno was impressive at 3500rpm she's pushing 287hp and close to 340 pounds of torq to the rear...

I have heard so many people's story on strokers and other high performance mods on 4.0's. Staying stock and staying healthy is the way I have chosen. I'm 23 years down the road in mine and going for 23 more.

Thank you for sharing your experience with us. This can help others. Wish you all the best

Thanks for the warning! I have a 2006 TJ I'll definitely be avoiding SNJ for my stroker build

The warranty for the stroker and their high-performance engines is exactly why I opted to go with their standard 4.0 with a tupy head over the stroker

I put a junkyard 5.3 L33 LS with 122k on it for 1100 bucks in my TJ. If it grenades, I buy another, 310 hp/335 tq. It wasn't rocket surgery to make it fit either, have 38k on it and still goes like hell. Trans is the weak link but spares are cheap enough.

You know, funny enough...my S&J 4.7 also has a leaking rear main seal. Including break-in miles, I have ~1300 miles on it. Also, the only reason I knew the warranty was for 1 year is because when I was talking to them I said something like "Wow, 7 years on a stroker? That's a no-brainer" at which point they corrected me. I do agree though, everything on their page made it look like a 7 year came with the stroker. Interestingly enough, my plugs in the block are all brass, but the ones in the head were steel. Lots of other small issues for me as well. Nearly all sealing surfaces were painted; valve cover, timing cover, thermostat housing, oil pan, oil filter, etc. I also had to remove a pressed-in pin at the oil filter that im sure if for the 90 degree adapter some jeeps used...but mine did not. The motor runs great right now, but with so many tiny details overlooked, i'm afraid of what could potentially manifest in the coming miles. I'm very interested to see how you edelbrock head experience goes!

My experience with anaerobic sealer. I have done several rear main seals now, the first three were done with Ultra grey and do not leak to this day. Then I learned that I was using the "wrong" thing and "must" use anaerobic sealer! That freaking seal started leaking with the first year!

Got a 97 tj with 230k miles, the lifters are a big loud but it runs good and still going strong

Had a 46 Golen installed in my 92XJ roller rockers, upgraded, mustang injectors, great motor no issues with the motor white so ever except the rear main started leaking at about 1000 miles called Golen and I did not cover the rear main. Loved the motor, not real fond of 4.0 rear seals.

Thanks for the video. I’ve been considering buying one of their engines for my YJ, but decided on rebuilding the engine in it as a family project in the garage. Luckily my dad has built many engines, and I’m skilled mechanically. Now that you posted this, I’m glad I decided to go that route. They also went up about $1000 in a year, like everything else has. Thanks for your videos. I appreciate the time you put into them, and the regular guy nature of them.

They should have done their due diligence. This kind of thing is what separates companies that genially care, from companies that are reputable , but doesn't give individual customers their full attention. Yeah the product may be good .. But what does that matter without excellent customer service. For instance , i know its not engine related but " MetalCloak" contacted me and made certain that i ordered the correct parts and the parts i wanted. When you spend top dollar on a product , you deserve top notch service .

Keep making videos!!! You make good content with good quality and information.

Thanks for sharing. Keep 'em coming

Thanks for sharing your information. Very well done video.

Not that anyone cares but. I Have a 1987 4.2 now 4.6. It was a simple R&R mix and match parts from both. With all used factory parts. I bought a rust bucket 1991 4.0 FI running fine for 1k took everything off the rust bucket sold it so I was money in the bank. Cleaned and polished everything pistons, crank rods by hand. Mild porting to just clean up the rough castings and built the stroker for dam near free with new rings, bearings and seals 12 yr ago runs fine still. Zero machine shop bill, dingle ball honed the cylinders hand lapped the valves/seats . Factory 2bb carb, ignition system. It's not hard and can be very cheap to do, yes I am a 56 yr old mechanic but anyone who can read and has the tools can build one themself at home. The only tool I had to buy was a bore gauge wanted one anyway. Has the same cam bearing, cam, lifters just put back in the same hole as they came from to match the wear on the cam and bore of the block. It really is that simple to build one. All the old pistions , rods are sitting here so thinking of a low compression build and adding a turbo now over the winter. If anyone wants to see that build. Comment and I will film it,

Dude please keep up the awesome video's!!!! I'm still on the fence with putting a 4.7 in my LJ.

Thanks for the video. I’ve been thinking of buying a 289 Mustang engine from S&J. Definitely gonna read the small print!

very nice looking jeep. Would love to see pics of it topless and doorless. this has to be a total beast with that stroker.

Nice Jeep. Nice work. 👍

Thank you very much for the Video. Sincerely much appreciate this share of experience. I have a 2001 tj perfect running 4.0... but have this 0331 head. No issues yet, but always worry it will fail on some long trips,so considering either a stroker.. or just new Edilbrock head. Bestvregards from Europe.

Sorry to hear about the problems you are experiencing with the 4.0. I have a 5.7 Hemi to put in my LJ and for simplicity I was thinking about doing a Stroker. Whatever I end up doing I will be putting a lot of thought into it. I love my LS3 in my TJ, thinking I’ll like that Hemi for my LJ too. I wish you the best moving forward with your project.. I have lots of Jeeps and this stuff can definitely be discouraging. We love our Jeeps what can I say.

Jeez that sucks. You chose the best route replacing the head, I did this with a Clearwater head on my previous Jeep, a 2000 XJ. Owners with the 0331 head engines have to be aware that many engine builders are just taking in core engines, rebuilding them, and then sending them back out, they don't update the 0331 head to the TUPY version, or care that it's an issue. On one of the forums I frequent there are a few claims from Jasper where they don't even consider the 0331 head an "issue" which is surprising. Hopefully once you do all the updates it will be bulletproofed and trouble free.

Love the video my friend that was very well done and beautiful jeep. That look really good. I also love that you actually have some SIDE WALL to those tires they're not 52 inch rims witch look so stupid. Just all around really like the look. Awesome job my friend and God Bless!!!

Thanks I've been collecting patrs won't go their ,good work doesn't need loopholes

I purchased on of their 4.7's based on reviews and some your previous videos. The sales rep I am dealing with was up front about the head and the warranty. He stated on all of their performance engines it's the 12-month warranty, and he cautioned me on the old head, and sold me the upgraded head (upcharge of $500). So, I'm still hopeful I will have a quality strong running engine to replace my blown 4.0. I sent them my roller rockers, that I was going to install on the old 4.0 and they are installing those at no additional charge to me. So I guess I will wait and see if I end up having some of the issues you are having here, but my old 4.0 has/had the same leaks in the same areas that you pointed out in these video. Keep up the good work, and great videos.

Great Video, I would recommend the felpro 9076 PT-1 head gasket and arp head bolts as well. Best Wishes

I was a Jeep dealer tech from 1998-2005 and to be honest I don't remember seeing any cracked heads or blown head gaskets and I was a engine tech. I'm sure it happens but it's not common with a 4.0. I think that was the strongest engine Chrysler had back then and maybe ever. Your TJ looks nice and hope you get it figured out. That new head should be a nice piece. Rear mains were so common to leak even with low miles .

Great video and excellent info. I'm also in the process of obtaining a new engine for my 95 ZJ (260k and still runs perfectly) so I'm in no great hurry but SnJ will not be getting any business from me now or ever, I will be going with Keith Newcomer out of Charlotte (if he's not too busy--fingers crossed) or Golen if nothing else. I'm keeping the Jeep for life so I don't mind sticking money in it but I will not waste it by going to a company that half-asses their work and their customers. Thanks for the "heads up" ha and good luck on your journey.

Great stuff and great jeep. I just posted a video on "an Everyday TJ" for my dad on my channel (jeepNdirt) as he's not a crawler but wants an everyday driver and the ability to just hit forest service roads and occasional off road basic excursions. I agree with you on the love of TJ's. I have a YJ (for over 21 years now), want a built LJ (future project), and currently have a very built JLUR (as seen on my channel). Now that I've helped my dad with his basic 3.5 inch lift 98 TJ Sahara on 33's I'm looking forward to getting him comfortable off road and maybe helping him decide on going bigger. LOL. Really love your jeep.

This is jeep is so cool

Been looking at some rebuild options on my tj. 248k and still running strong on original engine. Kind of just waiting for it to shit itself first but idk if it will lol. Don’t think I will get another motor after seeing all the probs and after spending so much money too. You seem very patient… I’d be pissed

I have a 05 Rubicon Unlimited with the 4.0. I replaced the motor with a Jasper rebuilt, it lasted for 500 miles then failed. I'm now on the 4th Jasper 4.0 and it just failed like 3 of the 4 other replacements low to no oil pressure at idle. The 3rd morot failed with a cracked head even before I picked up my Jeep. I'm looking hard at the Golen stroker to replace the POS Jasper.

I’m way too cheap to pull apart a perfectly good 4.0L , mine has only 51,000 miles on it

As far as the rear main seal goes never use the Fel-Pro or any other rear main seal except the Mopar from Chrysler. I have had to pull these down to do this after changing the rear main and it leaked from the beginning. I use Fel-Pro in just about everything else except 4.0 liter jeep stuff.

Been running my s&j motor for 4years in my xj got 40k on the 4,0 no issues but ya no follow up from them and the warranty..but they built me a motor and deliver it in 72hr..

Keep making videos! I like your content and can tell you really love your TJ. The rear main seals on these TJ’s will always leak. I hate to say you’re wasting your time changing a new main seal, but it will leak again in a year. I’ve owned my TJ since 2006 I had the rear main seal replaced in 2008, a year later it was dripping again and the main seal has always dripped just a little bit ever since and never got worse.

dam, S&J really seems to know what they're doing when it comes to not taking care of the customer.

Will learn together. Jeep community .

What’s the new power output of the 4.7 stroker looking to do it to my engine as well

Thanks for sharing, enjoy your videos. Curious if you measured the mpg on the stroker and compared operating temps with the original?

You are a patient man. To pay that much and have a gasket leak and main seal leak… ugh. Super frustrating.

You still have a legal path you can take for verbally telling you about the 7yr 100k warranty and not the 1yr 12k at the same tyme to draw your attention to your contract. That would mean you would have to have a lawyer anytyme you purchase a engine from them. The company misrepresented their product. You have a winnable case. Even if you leave youtube pursue like a tiger until they pay for the defects.

I got the same engine on the way, i clicked so fast youtube got dizzy lol. Well. I paid the extra $500 for the upgraded head. Hopefully that'll fix the that issue

Show me a 2-piece rear main seal in anything that isn't all wet around there. All my Jeeps always have a stalactite at the rear main, but I can park them on the most pristine concrete driveway and not leave a drop.

I'm fixing to purchase a Golen stroker. Came on here to here reviews about any serious stroker issues. But your head gasket leak, rear main seal leak, etc, can happen to any engine.

Would I go with a leaky head gasket, a head that may crack and a leaking rear main seal after 1400 miles? YES!

I like your videos if you have time. All of us run out of time.

No TUPY head! That is just straight up ridiculous from S&J! The 0331 no TUPY head is literally the worst head ever fitted to the 4.0. A couple years ago I bought a remanufactured Long block from ATK. (Has a TUPY head). Not a stroker. Just a 4.0. Did not want worse mpg. Extra heat. Or have to run premium gas. Within 1500km. Head was leaking oil in same place as yours. So I took the head off. The crappiest head gasket I think is available for the 4.0 is what I found. Single layer. And ATK also stripped the front right header bolt. So I installed a heavy duty head gasket kit. And new header bolts. 40,000km later still running good. But I would not recommend ATK at all. Why cheap out on the head gasket!? Very frustrating. Also rear main has just started to weap a little oil. Not bad after 40k.

TJ = Money pit! lol

In an accident your highjack on the bonnet will go right through the windshield.

The more I read about trying to get more power out of my jeep via turbo, supercharger or stroker motor seems to some of the time anyways end badly my 4.0 only has 40,000 miles on it. It does struggle for power now that I put a 3 1/2 inch lift in it with 33x12.5’s but by the sounds of it, I should save myself a lot of money and just go with it

I'd retorque my headbolts for the time being, sucks about the rear main seal

Are those 15x8 wheels? I like the stance👍

Two questions. I see that you have the vented hood. There's a lot of water. Get in there. And what is your miles per tank? Are you getting with the stroker? Just curious if it's even worth it

The more vids I see the more I'm leaning towards LS swap

At least they gave you gaskets 😂

That’s the difference between the front office/sales and the machine/ rebuild shop good quality product terrible customer service

How did you get a coil pack for that thing from MSD I couldn't find anything MSD for my ZJ and on top of it y do you only have little over 20lb plus injectors you should have a little bit higher than that and the stock cam come on man I have a very similar setup but the cam is not stock and I'm running 65lb fuel injectors

Why do you have the "65SEEJAYFIVE" as a logo if your running a 02 TJ ?

I didn't know the Edelbrock head came ported and polished.....🤔

Quick question...... Who makes the fuel rail you're running on the engine?

All the issues you've had and you would still recommend them ????????? Doesn't make any sense, you're a better person than me!!!!!!! There's no way in hell I would recommend a company like that to a friend or family, unless they have money to burn, which they don't! I wonder if the Golen engine would of been a better choice?

FYI the 4.0 will AWLAYS seep out of the rear main because it’s a 2 piece so not a perfect seal

Can someone send me a link for the MSD parts for the 4.0 would really like to throw that on my monster

That company clearly doesn't know what they're doing just by what block they threw in there and the communication issues that is a company I would never want my motor built by

I'm doing well today.

Nice Jeep! Great idea to upgrade the head, but can't believe you didn't get a mild bump stick to rasp up that idle! The best of us owned Jeeps that sound like they're about the stall out anyway.... By the by, you tell stories like my grandmother. Should have got a mild camshaft though. Also, you tell stories like my grandmother... Really love the aluminum Edelbrock head, great idea! Your stories are like my grandmother's...as well 🙃

2:22 he starts talking about the stroker

12:00 That's warranty fraud on their end. Straight up. It's not a "fault". The invoice and the packing slip said two different things.

Wasn't the issue that you have with the engine company right in the middle of COVID?

Kind of blows. At same time Ive never seen a 4.0 that didnt at least have a small drip from the RMS. Ive changed mine twice and it seals up for a couple drives then the blowby makes it leak again. If I paid new engine price yeah id be mad too

Fair enough comment.

What shop is $25 a hour? Most all are over $100/hr

Dayum man that sucks.

1800 miles and problems?

I can’t believe they would put a 0331 head on there, unacceptable.

Sounds like they are doing a bait and switch hoping people won't read the small print.

Drop a ford 302 v8 and a tremec 5spd and call it a day lol

After buying an engine from Dead Jeep and being ripped off? I trust no one on the internet. I will be building my own stroker engine, and parts from local places. It sucks to be your own warranty, but truth is, you are, warranty or not, you gotta rip it out, lol. Might as well save money.

You won’t more power 6.0 ls cheaper is horsepower 🇺🇸💪🏼

Customer service sounds terrible. No excuse for not handling your customers with honesty and integrity. We should all get back to trading on our name. I’m fortunate enough to be employed by just that. GL

that entire video and not one time did you start it up and drive it for us

Sounds like you're the victim of the ol' bait and switch for the warranty. Should have got a lawyer/ filed a civil suit. I'm sure you're not the only one this has happened to.

I got 304500 miles on my 4.0 still has 40 psi oil pressure and only ticks until warm up. Great engine

You're having issues because your wheeling with a motor that's barely even broken in yet you got to break the thing in before you beat on it brand-new motors can blow up at any moment to got to do the proper broke in When it comes to these things same with the 318 when they are fresh they want to be broke in properly

Building your own stroker would have been better…it’s not as difficult as you probably think it is and the tools are cheap enough plus you would have learned a lot in the process.

Told you not 2 , u didn’t listen to pick golen!

America love s Drama❤

In Europe you would had the your money back! In USA everything is allowed in bussines, love and war! You are victim of froad. But this is good way to tell other Jeep owners to avoid this scamming company. Sue this fucking company! I hate when Jeep owner is screwed!

Lol, one year and 2,000 miles later. 😂.

Why are so many of you buying these engines when you can build it yourself for cheaper, especially what this place is selling you as a “ performance engine” 😂 No performance cam or timing set, no roller rockers, cast iron shit head thats prone to cracking… leaks! Newcomer Racing engines are performance engines and they don’t leak from the head gasket, rear main seal and he certainly wouldn’t send you a head gasket and wish you the best. It’s not a performance engine without a performance valve train, performance cylinder head and definitely not without a performance camshaft & timing set. I believe they do not understand the meaning of performance. That’s a stock engine with a stroked bottom end … tell me it at least has forged pistons, rods and moly rings? Probably not, they probably put cast garbage in it… they’re making a killing and selling you guys a nothing burger.

$25 an hour ?? Thats CHEEP !

With all due respect, 4.0's should Never be touched on the block, cuz they're indestructible.

BS no one has a 25$ hr labor rate.

Blah blah blah lotta complainin
