How much copper spray do you guys (those of you who do use it) put on your headgaskets? Do you use only one coat, two coats, five, the whole can, etc?

 

i usually do 3+ coats, until the gasket has a solid coating on it.

 

if both the head and block are freshly machined flat you only need a very light coat of the spray on the gasket.......or even none at all.

a couple light coats is enough........no need to overdue it..........the more you put on the more chance of the excess being squeezed out between the head/block into some oil passages and plugging something up

I don't use it.

If I want copper in there I o-ring the block.

 

I used to use 2-3 coats. Just so theres a solid layer on there.

same

 

I've always gone by color, just making sure it's got a nice even coat.

 

i never use any...never have headgasket problems...like stated above...if i want copper there...ill o-ring the block

 

i dont use it

Ok, sooo if you don't use it then you aren't providing any useful information which means you need not post.

 

It might not be the answer you want to hear, but spraying some sticky crap that attracts every bit of microscopic debris floating in the air to party on your headgasket sealing surface is counterproductive.

Sorry to spit the truth as we see it to you. You may think this is your thread, but it's really a public posting in a public tech forum that other people are going to see and refer to in the future. I want to make sure it has some accuracy or failing that some differing opinions so the discerning reader can make up their own mind from all available information. I'd call that useful.

Then again I could be a smartass and tell you to read the instructions on the can... which would be the correct answer if the stuff works as advertised. Common sense is king, but some people insist on not looking in plain sight for their answers.

Happy New Year, bro.

 

We usually use about 2-3 coats on both sides, letting the copper dry for about 1min between coats.

And that is that. Best post of '08 so far.

It's not a thread debating whether or not I want to use the stuff or how effective it works. This is a thread asking how much others are using (and yes I also read the can). If others in the future are concerned about getting accurate information from this thread alone then they are flat out stupid. They should do their own research in other threads that debate the effectiveness....then come to this one and read about the quantity most others are using.

so why are you asking how much everyone uses? some use a little some use the whole can. not very accurate, you should take your own advise. i know 1 or 2 who used copper spray and did not use the whole can, just 2 or 3 light coats. the purpose of this stuff is not to lower compression or use the spray as a head gasket itself, it's used to cover MINOR imperfections in the head or blocks surface. a good question to ask is if i get some from globing it on, in the oil system and it goes through the oil pump will it pit the bearings? i don't have the answer to that because i don't use it, but would be interesting to see a response from real/professional engine builders.

 

The black nitrile coating already on the headgaskets is suppose to do the same thing. If the surface is not up to snuff, then i'll usually spray a <U>very</U> light coat. For the quick and dirty jobs, or one where surfacing blocks or heads is not an option I think it can serve it purpose ok.

Yea I know the purpose of the copper spray haha. If I wanted to lower the compression then I'd change the pistons. The purpose for me asking is that I want to see how much others are using of the stuff that have the same type of engine as me. It's called gathering as much info as I can and then making my own educated conclusions from what I read.

ok then dont use it, it would save u from tryin to clean that crap off everything when u take it apart next time

 

I use it in almost every motor, including those with fresh surfaces. 2 coats usually.

 

Well I never use copper spray anymore since I found Hylomar spray, its much better for sealing and its designed for race engines. If you've had the deck and head resurfaced perfectly flat, then you should not use it. If its only off by 0.001-0.002 then spray 2-3 light coats.

 

if all surfaces are flat and even its not needed. honda doesnt use it why should you??

 

I don't believe honda has any intentions on making high horsepower motors like we do. But what do I know about making any kind of power....?
