I just gave cometic.com a ring to see if they can custom make up a 924 MLS gasket, since they aren't listed. Sadly, it seems the answer is no. I was told that they would have to create dies to make the gaskets which would be "very expensive". Bummer.

I guess we're all stuck with stock or tempting fate with copper gaskets. I'm acquiring a stack of stock gaskets and was hoping a re-useable MLS would fix that.

Nick,

Try the following link:

http://www.horsepowerfreaks.com/price/Porsche/924/Cometic/Engine/Head_Gaskets

They list a mls head gasket from cometic for the 924. Don't know if you got a hold of a bad rep of what, but this may help.

Tom

That sucks! I was hoping to go the same route when I switched to the 931 head and turned up the boost. Copper doesn't really thrill me

I think that if we get a group buy together for ~100 of them, then it would be worth the setup. Yeah right!

The link above lists some kind of universal gasket. I don't know what it's all about, but Cometic definitely does not sell one for us. The rep was plenty friendly, so I have no reason to doubt him.

Sorry Nick, I just got off the phone with a rep from Horespower Freak. You're right, that's a universal gasket for a Toyota. He wanted to sell me a copper one, but I already have that. Out of a group of three thousand 924 owners you would think that we could find 100, three percent, that would want a head gasket. I'll take two, that makes only 98 to go.

Tom

Ok, out of curiousity I called back asking for more details. They would want an order of 150, which would ballpark at $85-$150 each (probably on the lower end), and would be a 3 month turn-around.

All in all, I don't see it happening.

I'd take 6 gaskets if we get a go.

Back before the Hausbrauen implosion, I went in with Mark Johnston for a composite head gasket from Lubbock Gasket & Supply. We ordered five, and I only paid $100 for mine (I think Tom Cooper was also one of the recipients). Now that they have the pattern, it should be cake for them to produce more.

I have NOT installed this yet, so I can NOT comment on reliability. However, the steel heat ring obviates the need for o-ringing the block or the head, and presumably the sealing problems common to copper will be non-existent.

FYI, the ones we had made up are supposed to compress to .050 (which I believe is a bit thicker than stock). I took this into account when I had Diamond and Holbrook collaborate on the block deck height and the desired compression ratio I was shooting for on my pistons.

I guess we should try different manufactures to see if we can get what we want.

Well, don't let the Hausbrauen curse discourage you from talking to the folks at Lubbock.

From what I recall, they were helpful and informative folks, and the price was right too. They apparently can do small runs, so for $100 per HG, how can you go wrong? I see the composite approach as a better alternative to copper or stock, and about the only one since MLS are NOT available at a reasonable cost.

Thanks for the info ideola!
I just talked to one of these fellows and he quoted $95 each with a 2-4 day turn-around and you would have to send them a stock gasket (which I've got plenty in perfect shape). Very reasonable.

Now my question is - what makes them better than stock? He said that the fire rings are steel and crush so they aren't reusable.
