Best Cylinder Head Seal

Supra Saiyan · 02-04-2011, 06:33 PM

I need to know what is the BEST Cylinder Head gasket sealer.. I used some crappy stuff and did a crappy job before sealing it up. Luckily 7mgte are built to withstand shithead moves like that. Sooo~ I want to make it right, or rather HAVE to make it right..

I need to know what sealer I should use that will last long..
I want to do this on Sunday..

ideally you shouldnt have to use any sealer, If the head and block are machined.....unfortunately most people dont have the desire/time/money to take their engines to the machine shop then deal with all of the "extras" that come with it.

So yeah, copper spray. just be careful to spray it on evenly and let it get tacky before torqueing it down. oh and make sure that ALL of the old gasket material is COMPLETELY scraped off, and use a good brake parts cleaner to remove ALL traces of oil from the head and block surfaces.

Good luck!

If you don't machine the head when it is needed then you are just asking for trouble. As well as cleaning the head and block surfaces is a must. The spray is just a good precaution to take which helps seal and improve heat transfer. It is most certainly not a cheap way to avoid the machine shop.

I never said it was a "cheap way to avoid the machine shop".
