Engine/Transmission (1998.5 - 2002) .020 thicker gasket

[RonA]

Does any thing need to be done about the change in injector to piston height caused by the thicker gasket?

Thinner injector washers.

Call Piers.

Yeah, the spray angles are designed to work precisely with a certain compression height. I'd call Don M as he has done a lot of research in this area.

The thinner washers work great on a 12V but they MAY cause you a problem getting the injector tube to seat properly on a 24V. Just something to consider.

I talked to mark at PDR yesterday and he told me I needed an injector install kit and that I should use the thinnest shims. Sounds fine to me. In regard to the tubes seating. I have never removed injectors before. So I don't have a clue what you mean. But I will ask about it. thank you for bringing it up.

Where did you find a thicker 24 valve head gasket?

 

[RonA]

I bought it from PDR. Turns out it won't work on my truck. My fault. Piers explained about the injector tubes. Another lesson learned.

"got to modify a 12v one"---the words from the late HVAC---he never did this to my knowledge--we looked at doing it, but we never did---some if not all water jackets are different(bigger) and maybe an oil passage or two--been awhile since I've compared the two---someone will know for sure---Joe D. can you tell us exactly---chris

 

[RonA]

Chris,

You are of course correct. The gaskets are made out of a 12 valve gasket. They can be ordered from PDR. Piers was kind enough to offer to take it back. But I want to make sure he can sell it. If this is a special order item I do not expect them to take it back.

The 12 valve gasket, 3283339, has steel bands along the exhaust side. They keep it from sealing the water passages along that side of the head surface.

.0.20 gasket

HMM kinda strange, i run a . 020 piers gasket on my 24v, seals fine, actually runs better than it ever did with stock thickness,

also didnt change shims, no probs on that either. 640+ at 80 psi.

guess i'll just take it out since everybody days it wont work.

Proram--good info--is your truck a daily driver also--just wondering... . chris

 

[BPINE]

I also put one in Cliffmans 24 valve truck, why can't you use it Ron?

 

[Partyat33]

Looks like modifying the 12 V gasket is easy enough. We made a template from the 24 V one and drilled it out.



Of course I have only had it on for 300 miles.

It would probably be best for you guys to email Piers and ask him why I shouldn't use the gasket on my truck. I know less about these things than any of you.

I ran a Piers . 020 over gasket on my truck for about 30,000 miles. It was a daily driver making 450 hp. The negatives: Hard starting in the winter, and I lost a little power down low.





The up side, It pulled harder up top. To really see a benefit with the . 020 over gasket you need to be making big power, and 450hp. is not big power. I switched back.

 

[RonA]

That is probably why Piers suggested I not use it. He knows I'm not looking for big hp with the twins. He does his best to keep me from doing stupid stuff,but it's a tough job for just one man.
