The base heads are fine... Change the springs before use and your good.

Its always the engine builders fault. I love it when you take in someones worn out junk to help them out and when it fails its all your fault.

Chinese = junk, lesson ends.

Procomp/speedmaster is the junk of the junk. If people need Chinese heads, promaxx are good with good parts. Afr enforcer is a dart platinum 200 copy with good parts. Nkb200 from skip white are the same castings wing good parts (not as good as afr) . Stay away from complete heads from China. Their valve train is garbage. 95% of Chinese rockers are garbage, all Chinese lifters are garbage. Procomp/speedmaster!needs to be shut down from the junk they sell but people keep buying it because it's cheap.

Goddamn!!!... that's a serious ball point pen!!

Can you ACTUALLY buy American made heads these days?? Isn’t the American way all about the MIGHTY dollar and screw the consumer?? Don’t get me wrong I love the country, it just pisses me cause you had the best… (PRODUCTS and ATTITUDE AND PRICE), now it just gone to s**t…. 🤷‍♂️😢

Another excellent video from Pete, covering all the bases to seal and clamp cylinder heads! The term torque is used as a catch all for fastener tightening but it is just a means to an end. The ultimate goal of the fastener is the development of clamp load which is final result of the rotational energy applied. A simple torque spec is good enough for standard care fasteners where stretching/yielding the fastener is not necessary but for the critical joints like heads, rods, mains and flywheel/flex plate you will want to take full advantage of the mechanical properties of the fastener. In these cases a torque + angle spec is used to minimize the clamp load variation resulting from friction coefficient changes! By implementing a low threshold torque and then turning the fastener a predetermined number of degrees, influence of the friction variation between the under head bearing area of the fastener and the thread interface is minimized. The amount of clamp load developed is thus controlled by the material properties of the fastener and the thread geometry because every degree of rotation equates to the amount of tension the fastener is under!

lol American made oh American assembled but made in china….. lol

why keep supporting china?

Buy them unloaded . Buy good parts clean up guides etc

I hope the views were worth it 🤷🏻‍♂️

It would be nice if all this care was taken building my engine. You guys are liars and crooks. Stole parts from me. Lied about all parts used. You are a joke.

😢

I buy the Chinese heads for port and polishing jobs. All of the hardware gets removed and most of it gets replaced. The castings are perfectly fine.

Hi sir do you purchase heads from china we are the manufacturer

Ruel number one in the auto industry, never bag out someone else. You don't know the situation that lead to the failure, the customer could've been advised but refused, then you blame the other workshop.

i like this video because it puts into perspective how dangerous speedrunning rc cars actually can be and why you should always plan these with safety in mind

Any experience with Fel PRo Loc wire? O ring and coolant sealing all in one.

Well i think its am illegal technic 😅 traxxas might not approve @Traxxas

Yeah pretty well known to buy these heads bare.

Well now you say you polish turds...I guess you could also flush those turds! I like what you're doing.

It's a couple of inbrededpofs

Sue them Bozos

I didn't even know this was a thing. I knew soeedmaster and procomp was making stuff there and those are two brands that you don't want to get involved with. I was looking at the prices of these on ebay and they are cheap. However I have dealt with detroit diesel heads that come from third world countries and they can't build those things at all. All of them needed to be surfaced right away. We had one where the freeze plug kept leaking because it was manufactured wrong. They didn't install the valve guides straight. The seats were not machined or installed right. The keepers for the lifter arm retainers were horribly wrong(they popped out when we installed the head). Even the machining in the ports were terribly off. This was just five heads and they all sucked. Honestly just get the good brand heads with quality. You buy these knockoffs and you will be crying because they will either destroy your engine or cost the price of two sets of AFR's to get them machined with proper equipment. I would only buy these heads if I wanted to make some art projects.

It looks like The shocks unloaded after it smoothed out just enough for wind to catch it 😬😬

Anyone with at least 2 brain cells can see that you take pride in your work and even have proof in this video that if you aren't 100% certain about something, you will say you don't know. I appreciate the effort that you put in and all of the knowledge that you share. Keep it up, Pete! You are real good at doing stuff 👏

Hello from Oamaru Sth island New Zealand. Do you advise to dress head gasket with Hylomar spray on prior to installation?. I'm replacing a gasket on my 2012 Nissan Navara D40 St-X Diesel common rail turbo engine

CAVEAT EMPTOR LET THE BUYER BEWARE

Think you Joe Biden you are the best president in the world sell every thing to China you are the Best thank you ....

Who are the companies that are American made that does not outsource their parts, jegs,summit and host of them are bought off by chinese companies, we are frustrated ?

I'm sorry to hear that someone is making up falsehoods about your work. I've had to defend folks and be defended from folks associating me with some made up crap with no evidence. Thanks for the info on the head gaskets. I've never used the cut ring gaskets and I might look at them. I will tell you that my wastegates got stuck one time at the track and I them lose water at about 50PSI. If not for the fuse built into the gasket and me feeling that I had a HUGE jump in power and getting out of it I would've been rebuilding an engine and 2 Turbo's also.

This all seems so obveous to me. I found your channel c/o Cletus McFarland’s channel, and Leroy! Why you no make more videos?

Do you do 243 head porting? If so a cost please

Your XO-1 did not die in vain. 601k people are entertained.

the seats don't fall out as much as they did, hahaha think about that a minute

At that point buy a whole new car lmao

Nothing good comes from China

I would be peed off if I crashed a expensive rc car like that

Wow this is the most brutal crash ive ever seen 😮 just wow that must have feel terrible 😮

Well said thank you for the great information They say imitation is the highest form of flattery

Great info. From an old bloke down under

The worst thing about this situation isn't even the fact that you ruined a 1000 dollar RC, it is the fact that you have to tell the wife you ruined a 1000 dollar RC...

Would it be possible to turn some hoops down on the lathe from pipe?

Did it survive

Great intel on head gaskets:

What’s your thoughts on retorquing?

You guys should use (neatly) cut beer cans around your exhaust, you’ll b surprised how good it work when done correctly. Have them raise from the exhaust 1/4 inch, a mixture of tie-wire and washers or spacers is all you need too fasten (and raise) too the exhaust

raise the back few% stiffen the springs all round-more so on the rear. You need too know in kilograms the downforce at that speed and your springs should be compressed no more than 20% at peak speed.

Completely epic!

many years ago I lived in Black Mountain NC and tuned Saabs .... I had at the time competitors who would lie or twist the truth to make me look bad... I say that to say I know what its like to deal with that personally and it sucks :-( Im sorry you have this kind of crap do deal with. thanks for sharing your knowledge. Live with Honor and integrity.. even when others do not!
