i pulled my heads and cometics gaskets. the gaskets have a lot of the old gasket material on them. so i cleaned them the best i could but everytime i pick them up i see more crap on them. how clean do i need to get them? every time i pick them up i see more crap between the layers .seems the old gasket material is everywhere.

 

Use some brake cleaner to get all that stuff off. You don't want something like to be the reason the heads don't seal.

 

FYI, I have used copper-spray sealant on my last three Cometic installs and have had no issues from leaks....

Get that thing together!!!

 

so soak the cometics in brake cleaner?

 

Are you trying to clean the old (used) head gaskets??

 

Yes he is, you can re-use Cometics...

 

We did the same...

 

You don't need to dip it in brake cleaner. Just spray it off. I also use copper spray on mine before installation. It sounded like there was dirt or other stuff on the gaskets. It only takes one can of cleaner and 5 minutes of your time to clean and prep them. They can be reused a couple times from what cometic implies.

 

Who makes the spray and where can it be bought? Is it a permatex blue can? Is it available at Autozone?

D

 

Yes, you can get it (Spray Copper Sealant) at Autozone... The can I got was copper in color...

 

ok ill spray them with the brake cleaner then. theres no dirt on them just alot of the old gasket material from the original head gaskets. i got most of it off but i am always finding more here and there

 

Are you saying the original heads were not cleaned thouroughly before the cometics were put on??

 

I keep cleaning both my heads and deck but when I removed the heads after claying the piston, I noticed an oil residue on both sides of the cometics. I dont know where it is coming from. Does this affect the sealing properties and is aybody else seeing this?

 

Ive been hearing more and more about guys having problem with those gaskets

 

the heads were cleaned but i didnt get 100 percent of the stuff off the block. i had no leaking problems though

 

?? Like what...i've knows a LOT of folks who use them? I use them. Make sure they are oriented corectly, torqued correctly etc. They do an especially good job at matching iron to aluminum.

 

No issues here... I have installed 4 sets...

 

I guess I need to put copper spray on my "to get" list.. My ETP heads should be here in about 7days or so ARP Studs just arrived, yes!

 

the hell with it- i bought a new set of cometics just to be sure i dont have any problems. i did reuse these old ones a couple times though with no problems what so ever

 

What I was trying to figure out, where did all the crud come from. Wasn't sure what was being cleaned.
