I am an engine machinist and I can tell this guy is immensely knowledgeable and honest. I work for a cranky old guy like that and I try to learn everything I can

The machinist sounds like he knows his metallurgy. Straightening head in an oven...seems like a lot of it is much an art form from experience as it is science

That machinist is a real character! Outside the box thinking about how parallel planes are equally affected with warpage and the way he explains it was phenomenal to hear. And then his explanation about how he would proceed to correct it. (Retired A.S.E. Master Auto & Truck Technician and working small shop owner.)

One of few that knows his work... I've been at this 50+ years and he is one of 3 I know that is spot on

This was a great lesson in root cause analysis. Thank you for taking the time to examine the engine carefully and recognizing the gauling as a symptom rather than the cause. Your machinist was spot on amazing descrition of the root cause and fix procedure.

Machine shop guy is legit!

This is very interesting. I have heard people go on about putting a thicker copper head gasket without flattening the head and torqueing it so it flattens out enough. Now I understand what they are talking about, the top of the head gets affected when one surfaces the bottom and more damage results. It's a full head job or nothing.

Wow that’s a honest rebuilder there. Most ppl will just take for a ride and rip u off , he said some good info on rebuilding a engine that I never knew

So HARD to find even a decent Machine Shop. Glad you found one 👍🏻

I was a cylinder head machinist for 15 years and this man is correct. Nearly every aluminium OHC head that's seen huge heat or compression issues will need straightening before anything else. Not all mind you, but most. We never line bored the cam tunnel however, we only ever honed them so that we didn't take out too much material. Straightening the head involved heating the head up on a press with a jig and then locking it into place by melting certain points along the cylinder head. When you go to surface the face after this it would blow you're mind just how badly these chunks of metal could warp. We constantly checked that the cam/s turned with all caps on during the entire overhaul process, as well as checking that the bucket bores (if used) were also round (straightening the head also threw these bores out of round too which could lead to jammed tappets and open valves, simple honing fixed this too)Then you may have the issue of the head being too thin from multiple shaves which can lead to timing belt/chain failures and valve to piston clearances. After pressure testing the waterways, fixing up the guides, seats and final surface the entire head would be assembled and cams checked again to make sure everything was free and smooth. The only other problem we use to have with alloy heads was softness. Too much heat into an alloy head and it would never torque down properly because the head bolts/nuts would literally sink into the aluminium while tightening. Hardness testers were used after straightening and if it was too soft it was thrown into the scrap heap. Kind of miss this work when I watch videos like this.

Love this video!!! I always have to know why something failed rather than just throwing parts back on it!!!

Love keeping old Supras alive. Very interesting head info

Valuable lesson for me about a straight head. Thanks Faye - much appreciated. I have never heard any shop talk about straightening a head.

You've got a good machinist, keep him for life. And we got a little chicken 😋

That fellow has a Golden Foundation under his Skills Set. 👍👍👍👍👍

I'm over 50.... NEVER heard 'straighten the head' ever. Wow. Great video.

Thanks Faye....I did my head too....way worth it....mine no headache till now. 4 years already... 1994 model....so smooth....paid 2k to rebuild cylinder head...water leak resealed, valves replaced, springs replaced, valve seat replaced. Washed coolant stains...

It's great to see someone who REALLY knows their craft.

That guy is a character, definitely knows his trade/craft. Most performance and engine building shops have individuals with this kind of knowledge. Your typical machine shop is just good at machining.

when you find these kind of guys, you hope they never get old. You want them working on your car forever. I have found the best, most honest mechanic, but he's no spring chicken. Often times, he'll tell me what/how I need to do something myself so I can save money and knows I can do it correctly. He's a keeper.

I am so happy that Danny can fix the head. There are so many machine shops that just let the machine do the work without actually looking to see what caused the original issue. Most of the good small shops have closed. I'll need an align bore done to my VW in a couple of years and I have know idea where to get this done. It is sad to see all of the knowledge vanish. This is one of the major reasons I love your channel. You take the time to explain and do the work. Filming Danny was EPIC! Thank you! Have a Supra Day! (Pun intended) - Jim

I wish all machinists were as friendly and knowledgeable as that guy. Good call on pulling the cams/head to check everything out, that should definitely save some headache in the long run!

Just watched this all the way through simply because of the way you explain thing's with your passion for this motor, and how any good mechanic should always check the manual to make sure it's all being done correct. Like another of your follower's, a Jeff Keryk said, this was the most fascinating video he has watched! I totally agree with him, as even though i know only so much about the workings of an engine, what you said at the beginning about needing to know what the smoking gun is, and how Danny Soliz explained what most people do, and what he know's should be done, captured my attention and made so much sense to me. Brilliant video, love the passion and the laughter. Looking forward to the follow up.

Danny!!!! Cheers man. That was great. Thanks. Thanks for bringing Danny to us, Faye.

Love that machinist, he know's his stuff and you can tell he will only do the right thing, very few and far between with that approach and knowledge. I have learned something here, which totally makes sense. He reminded me of Danny Devito as well, legend.

Danny is definitely someone I would trust because he seems concerned about quality not just about the money. Thank you so much for sharing. Very interesting and informative.

Blow my mind. Every one always speak about resurface the bottom. But this make more sense. Will never do this mistake my self. Thanks to this video. :)

I've been wrenching maybe 10 years and never got the message about "straighten vs. deck the bottom". Keep spreading the word, wow!

I love the sound that super tight bolt made when you used the break over bar to remove it. Cool gut too. He’s good at describing the why. Very important.

What he said makes perfect sense, that is why in my service manager days I saw so many cylinder head jobs fail on older vehicles. The top is never checked especially when I took them to the machine shop myself it was always the bottom. Especially with aluminum heads, thanks Faye for that informative video.

This is the most fascinating video I have ever seen. Wow! Thanks Faye.

Wow that machinist is amazing! The thoroughness and knowledge is crazy! You are lucky to have a fantastic machinist like him!

That is really good...you can see honest machine guy who will tell you exactly what is going on with head i really appreciate that.

First I've ever heard of head straightening. Thank you!

Yay chicken!!! Loved this video because of the knowledge bomb. Also because your uplifting personality is contagious and we all need a Monday morning pick me up. Have a great day!

I just recently found this channel, and I am glad I did! I admire the professionalism with which you do your work, how well you do on the videos while also getting work done, and the fun demeanor with which you do it all.

one dealer I worked for had a machine shop that was an absolute wizard with aluminum heads, he would straighten them first, to be sure the cam would spin freely, he could spray weld aluminum onto the head surface if he needed to remove any pitting THEN resurface the head, we never had any issues with his work, walking into his shop you’d think he was in the 30’s but had some super modern equipment as well as ancient tools.

Danny could have his own channel or TV show. He's a genius and a natural in front of a random camera!

Two rock stars getting it done!

Great video, love working on older stuff and seeing others do it too. I’m guessing that funny cam cap order you showed is designed to match the relative spring tensions at TDC so when you back them off it minimises strain and distortion.

Great video. Full of information. Danny is clearly THE Man. Keep up the good work Faye

Fascinating. I love when ppl have deep first hand knowledge.

Man that guy gets so pump up of all the info he knows. Thank you, and what a great guy. Please the follow-up

When grabbing 2 flats on a round shaft the adjustable wrench has the advantage of closing completely on the 2 flats with no play. The "correct" wrench will still have some clearance which will cause wiggle under high torque. You have the right tool for the job.

Wow, this guy just broke it down so simply that I understood it the first time. Imagine having a teacher in school lile this. So awesome. Thanks for sharing

very smart man & he makes sense. I especially liked his comment about not resurfacing the head first. Straighten then resurface. Logical

omg that guy loves his job i want him working on my car

So cool seeing the diagnosis , thank you Faye!

Greetings from michigan. Here in.my misspent youth, many machinists had the fastest rides. Everything balanced, blueprinted and a healthy dose of that machinists BLACK MAGIC. Lucky lady to find one so wise. Sadly men like these are becoming difficult to find. Looking forward to more vids.

Amazing video. That machineist sounds like he's old school with a lot of experience and a wealth of knowledge.

This is pretty cool. Definitely a good thing to know for people with overhead cams. On a side note, I have major trust issues with 7M-GTE's. Props to anyone who can keep these things alive.

Good finding, finding a reputable machine shop and knows what they're talking about is hard to find.

OMG, You have the best Machinist! his words are Gold!

Clicked on the video and was like "Eh...sorry for you and your Supra, but I'm not really interested." But it got better and better and couldn't stop watching 🙂 Fascinating stuff. Reminds me of a great mechanic my dad knew when I was a kid; he went by the name "Crazy John." Dad's '82 Impala knocked and needed a valve cleaning. He asked my dad for 50 cents, went to the vending machine, got a Coke and had a sip as he told my dad this. Car was running with the air filter lid off and he turns and proceeds to rev the engine as he poured the rest of the Coke in to the carburetor. My dad nearly shit! Crazy John turned back to him and gave him the bottle and said "There, I just saved you a few hundred dollars on a valve cleaning."

Ms Hadley, I have to say you're incredibly upbeat and positive when working with what many might find to be frustrating, especially on your own vehicle.

Interesting video! The 66 guy is cool. Thanks for sharing this. Can’t wait for part 2.

Glad your back love, dude at the machine shop you can tell he’s old school he knows his stuff

Dang ole 7m, it's good you are doing this cause they are notorious for head gasket issues, it's awesome this engine is gonna have a new lease on life

There is no replacing experience, your machinist is awesome.... Great video, love watching you work...🤘😋

Absolutely freakin' amazing. I had no idea. I'm looking forward to hearing more about this. And thanks for the cameo from Daisy.

Wow... could have used your help 20 years ago. I had an ‘84 Supra that I absolutely loved. Had the head and cams machined ...twice! Second time I took it to a shop to have the work done, figured I screwed something up the first time when I did the work myself. Ended up selling her. Now I find out the head was machined wrong... 😢 Awesome videos, Faye. Love your channel.

Your machinist is very intelligent. I like his critical analysis.

It’s amazing how you go by the book. Most guys just take the dam thing off and just skip to the next clip and say it off. Thanks for the detail work

Great video, Faye. That machinist is amazing! He knows exactly what's going on with the cylinder head on your car. Looks like you found the smoking gun too. Looking forward to see the rest of the repair and how the car runs after it's done. Thanks for including "Silkie" in your video.

WOW Danny blew my mind at first but what hes saying makes total sense! I never would have thought about that before now. You definitely have a great machinist there

I was looking for some DIYs for my 09GTI and this was in my recommended videos, glad I stumbled across your channel, it's quite refreshing.....subscribed!

Having a good machinist..as well as a good paint & body guy/gal ...is PRICELESS. Sadly...hard to find today. Thanks for sharing...enjoy watching and learning.

Brilliant man! Never heard that before. Makes perfect sense!

Looking forward to hearing more from him he definitely knows his stuff 👍

When I seen you bring the head in with all the valve followers still in, I was thinking to myself, oh god the machinist is going to muck up all the shims or loose stuff. Wish I had a good machinist near me like that.

My first new car after high school was a 1983 Toyota Supra, yes I am old, and it was the best car of my life. Yes it wasn't the fastest but it was a very unique-looking car and rock solid reliable. Very interesting listening to a skilled/experienced machinist and his simple but detailed descriptions of the warped head and the cam relationship. I too would have thought a valve job and machined head would have meant they were better but I can see if you only do one the other could be made worse. Great video and love your easy-going style and charm.

My goodness i could listen to you talk all day love your voice and that smile😍💜

Very informative video, plus your laugh brightens my mood. Keep rocking girl!

Danny knows his stuff even better than most car engineers.

Wow, I am definitely coming back for part 2 of this video.

I’ve spent many, many years turning wrenches. I had never seen anyone who had a way to straighten a head! That is amazing! Unfortunately, I don’t think any of the machine shops we have up here have the knowledge or equipment to do that.

Wow this is getting intense, can't wait to see how it turns out, very educational!

Hi Faye , looking Awesome, looking forward to the finished works on the Supra 🌹

We all just want the job done right. You are right Hill Country is the best Wow wow wow. Great job exposing the real issue with that problem. Love it. Wait at the end it looked like the pavement was moving .

The warp and don't machine part really blew my mind,never thought about it like that. Goes to show people that if you don't have the money to go all out then save your money till you do.

More epic Faye Hadley! Lol! Nice job! I had forgotten this issue! Thanks for sharing!

I like that guy! He's cool! I always got excited to see the behind the scenes in a machine shop. My machine shop is awesome too!

Great video Faye! Watching this makes me really want to dig into the MR2. Keep up the great work!

Wow, very interesting. I didn't know what was involved with this. Keep the great videos coming, thanks.

Reminds me of my old man he explained this concept to me when i was younger...i would def bring my heads to this shop 💯👌🏼

Thanks for postin this info about straightenin the head. He gave much technical info that makes pure sense.

Another machinist here to say this guy knows his thing. Great video series with this man!

Danny the machinist sure is a treasure trove of info!

Nice job, Faye. Thanks for bringing us to this machine shop with you. I learned something today!

This is AWESOME! Some really cool info in here. Thanks for the great video.

your lucky to have found this guy. every machine shop i dealt with have all gone away. i just thought it to be a normal thing. kind of like tuning up the car. a thing of the past.

Those looked like brand new Capri tools as for the adjustable wrench when your not in your shop, your glad you got anything that works. Good Machine shop knows his stuff. Side note I have found that tub of towels works very good on tool clean up no harsh solvents also works for your hands as well. It's very good at getting the grime of the Capri Led slim light. Keep up the good work

I never stop enjoying, and learning from these videos. I always seem to find myself enjoying your laugh a lot too.

Yupp!! I have an 84 22r head that was murdered by exactly what Danny is talking about. I didn't understand it until listened to what he said. Thanks for this

That was the best advice I have ever heard from a machinist. Great vid😀

You’re so awesome Faye! TY for the education!

one of the most real youtube people ive seen in a while seems so genuine ........

I have only heard of one other person having issues with the cam bolts backing out, and that was on a 2j. I have never had any issues on 5m, 6m, 7m, or 2j engines myself luckily. I will be sure to have the machine shop check the straightness on the cam saddles before they surface my head from now on though. Literally learn something new every day.

What a fantastic video. Thank you for sharing this.

Danny knows what he's talking about! Excellent channel. Subbed
