Does it make them seal better?

SIXTY-1HATCH

Not really but i always spray mine anyway just seems to help them stick, either way you look at it just make sure you torque it in the right sequence and you should be good

I use it everytime I do a headgasket. Can't hurt ya know? If it actually works then nice, if it doesn't then its still in my head that it is working lol.
Plus its only like $5 for a can of it.

You will find mixed reviews on this of people swearing bye it and swearing against it. I read an interesting post that talked about how use of copper spray on any MLS gasket, makes the gasket not function the way it was designed. I will see if I can dig it up it was in a DSM forum..
When I have done all of mine I have not used it, but then again I had my block and head surfaces redone each time. If you prep your surface areas the way you are suppose to there should be no need for copper spray or any sealants to help your gasket seal. It should seal just fine. This is me though, like I said there are many that use it.

My machinist recommended this permatex spray a gasket stuff. Its red and is REALLY tacky. Im not sure if it helped or not but ive had no problems with it for about 15k.

i jsut left the machinist here and he said not to use it at all.. if you can understand this with teh stock honda headgasket its designed to shift around to accomodate for the cylinder flex... he says teh copper spray creates tacky parts and dosent allow your cylinders to walk in the directon then should making it harder on your crankshaft.....i went threw 3 head gaskets that i al copper sprayed... so im trusting him this time.. and that was all with a decked head and block..

here is my thought...... the guys that spend countless hours desingning and building these things dont use it do they?????

they know more than we do and they design every part to function together as a unit. when it comes to headgaskets i check the deck of the head and block and use only a honda headgasket and NO sealer. MY .02 cents

a headgasket is not supposed to move around and cylinders arent supposed to flex that much either... Sounds to me, like hes not exactly up to par on automotive tech.

haha well thats your own opinion.. considering hes responsible for all motor builds here, jsut a thought.. it is montana, and considering there is such thing as "cylinder walk" his comment wasnt far off by any means, what do u expect the cylinders to do under load in a open sleeve?

I expect my cylinders to stay put, especially a sleeved block. I can see a torsional .001-.003 movement maybe but not enough to cause headgasket leakage

no ****...
cylinders moving and crankwalk is for dsm's

damnit...double post..
but ya I used gasket spray/sealant on damn near every gasket on my engine (different kinds for different parts obviously). it could only help...i would think..

Although, on a side note, one time i bought that red silicone sealant for oil pan gaskets. While i was sqeezing it on onto the gasket, the ******* tube exploded all over my hands! Talk about a bitch to get off....water just spread it around and orange cleaner did nothing...I had to use a wire brush and scrap it off my hands, it was horrible :end rant:

I use it also. It's supposed to act like a copper gasket that's all. When it is dry it is not sticky anymore. It is know that copper crushes and seals better this way. That is all it's for. It will no stop your head to cylinder from moving (witch I never herd of anyway).

I always spray mine, it makes me feel better.

ive heard that caterpillar has sealant that they use on hg's on their diesel motors and its really effective even for our applications, but thats just hearsay. ive used copper spray and never had issues, ive not used it and never had issues either. lol

copper conducts heat very, very well. so when you spray it on the gasket, and start the engine, it gets very hot and expands and helps seal every little imperfection.
with the copper spray, after you spray it on a gasket you can look at it in certain lights and see it covered with copper "glitter."

Caterpillar doesnt use any form of spray on their headgaskets...

with a fresh deck and fresh head i went through 2 copper sprayed oem gaskets... but this one i put on yesterday seals fine without copper spray... i think it ***** em up... maybe there is different copper sprays but this one appears to be eating away the nitrate composite on the gasket

EFbomb

I've never used it, and never had a problem.

But I was told if you have an aluminum head and iron block and if your headgasket is a multi layer steel(MLS) gasket that using copper spray is a must.

never tested this advice though

hotrod99

what about Cometic headgaskets,can you use copper spray on those?...ive been searching but i cant get a straight answer.

I cant see how some sticky adhesive can hold hundreds of psi but it cant hurt so I use it

It's not the adhesive, it's the very tiny specles of copper in it. The adhesive just bonds to copper to the gasket and the copper specles expand to help seal everything.
