Grease on Copper head gasket

Blown Alky no water Engines

I'm looking for something faster than cleaning off the silicone from the block, gaskets and heads.

Do you use grease on yours?

I'm having a hard time convincing myself that grease would not leak cylinder psi and oil.

Thoughts?

 

I put my copper head gaskets on dry. O ring in the heads and receiver in the block. I've been to 35 psi so far, no issues. They pop off like nothing. Unless im not understanding the question.

Was your block ever decked? If so were the sleeve registers dropped as well ? They’re all over the place from Brad. I set mine down at .002-.003 now and block seals up awesome. But the oil holes still seep a little

 

You are understanding, maybe I don't put anything on them, hmmm.

Grease seems like it will make things slippery when we're trying to not let any oil or psi "slip" by

 

I just realized that i believe you run a hemi where im a chevy. I believe you have oil to control through the gasket? Where i don't have that issue im only controling cylinder pressure with my gasket. However the oring should handle all cylinder pressure could you switch to a not hardening sealant like hylomar around your oil holes. Then a person could just wipe it off not have to scrape.?

Have tried hylomar. Found the most of it in the filter

 

No hemi's here, only conventional headed chevrolets at 30-35 psi boost.

Dad built his 1st blower motor in '76 and taught me to use high temp silicone in an effort to not let oil seep out from the lifter valley to the outside of the head, but I'm wondering if its needed at all

 

Ok, so exactly the same engine as i use heads as. Well. Dry gaskets. No leakage. Learned that from shear ignorance, didn't know any better when i built my first blown chevy, never saw any leaks of any kind so really didn't know any difference.

Have had decent luck with Hondabond.

 

Thanks everyone!

 

Hey @SoDak use Crisco, it works the best!

 

We use Lucas 575 degree high temp wheel bearing grease....works great...just wipe the gasket and re-apply when the heads come off...no more cleaning silicone off of the head - gasket - deck surface with brake clean or solvent! Just smear a light coat of grease on both sides of the entire gasket...

 

Hi temp wheel bearing grease here also, BBC 40 pounds. Solid heads. O ringed block reciever grooves. No issues. Cleans up easy

 

I use Permatex anaerobic flange sealant. Cleans off much easier than silicone products.

 

@Catman and @Nitro Madness
For what reason do you put grease on at all, if you leave it off does the copper stick to the block or heads?

 

Since the sleeves are about .005" higher than the deck surface on a hemi - oil seeps from the valley across the deck surface and leaks along the outer edge of the head...runs down the side of the block...
This thread is referring to using grease rather than silicone to seal the valley area from leaking oil...grease is easier to clean up and re-apply if ya hafta yank a head between rounds...

 

Try Spray copper gasket coating.

 

That makes perfectly good sense about the sleeve protrusion, we have about .003" sleeve protrusion and have been using Lucas Red N Tacky grease on our head gaskets for the past 3 seasons with great results, no leaks and much easier to clean up when the head has to be removed!
