$113 ea. from the dealer.


This is for my FD. So if anyone knows where I could get a cheaper replacement or price please post.

Thanks,

 

make one out of cork
or just weld your turbo manifold right to the block!!

 

I heard from Leigh that KY is a good sealer

 

Go buy a sheet of copper and trace out the old gasket on to it. Get a pair of tin snips and cut away.

 

can someone else back up this idea? i have access to this for free! i could prolly make some money makin gaskets if this is true

 

Pure copper, annealed to get some softness to it. This is a common piston motor gasket material.

I would get it cut on a waterjet or some better method than tinsnips though, I never manage to keep what I'm cutting very flat when I use tinsnips.

 

cool, have a plasma, will still leave a little bit of a jagged edge, but it should be fine.. thanks

 

Where can I find sheets of copper?
My gaskets are constantly getting blown out after some nice driving....

 

look for a sheet metal suppiler in your hood, 3x8 seet is about 100$, thats 24 sq ft though, will make alot of gaskets

 

got metalsupermarkets.

bring cash, and say you don't need a reciept. Try to find off cuts or small peices. Usually industry can't use small peices so it goes super cheap to us hobby guys. I mainly deal with the brampton store. They know me as teh guy who managed to walk into the door 5 mins before they close on a friday (I go after work).

Anyhow... you can just a jig saw with a fine tooth blade. Trace out he intake or exhaust manifold gasket on a market. Drill it out and jig saw it out. Fine tune it with a deremel and a high speed router bit or a 1/8" carbine end mill.

If you warp the panel / gasket with tin snips don't worry about it. Get the Propane torch out and heat the copper until it turns blue'ish and remove the flame it will anneal. As you torque down your heads/exhaust mani the copper will take the shape. Just becareful when you are making the cuts near any bolt holes/mounting holes. Those are areas where leaks will occur if you cut too much material out.

good luck.

I called brampton metal supermarkets, they said they do carry copper sheets, but they don't have many. Thinniest they have is 27 thou. Not sure what else they have.

How think should be the copper gasket be?

 

I've never made copper gaskets, but I've made plenty of paper ones. It's only my opinion but I'd figure that as long as moving part clearances can't be affected, anything thick enough to squish and seal irregularities on the metal surfaces should be enough.
