L20B copper head gasket

[Danny]

Does any one know where to get a copper head gasket for a L20B?

 

Thanks

Danny

I orderd one from the local Auto Value a few weeks ago. I'm sure any auto parts store could get one in a day or so.

You planning a turbo motor?

[Danny]

Yes going to start a turbo build soon but first need to bulid a L2300.

local Auto Value ???????????

I think that is really is the FELPRO shim spacer.

 

There is a place that sells them like 100$ or so.

What are these copper headers for? (noob question)

It's a solid copper head gasket. Copper is 'soft' enough to form a good seal and won't blow out.

Danny you should really see about having the block O ringed instead of the copper gasket.

[Danny]

Ya I was going to look into getting the block O ringed but have not had time to see what it would cost.

[datzenmike]

Well you will need to have bored so get a shop to do it while there.

[TENDRIL]

what does O ringing do for it. does it eliminate the head gasket all together?

[datzenmike]

I don't think so as the gasket still has to seal the water passages and one oil feed hole up into the head for the cam. The wire in the O ring tightly pinches the gasket and seals it fully.

Another noob question, would a copper head gasket be better for my LZ motor than a regular felpro?

[datzenmike]

I don't see how really. Regular gaskets are adequate and I never hear of people using the copper ones.

Would you be able to get an overbore copper head gasket? Because if you bore the block out, the gasket would hangout into the cylinder, right?

[datzenmike]

Depends on the overbore,... 2mm would be a lot and that would only be 1mm all the way round. The gasket hole may already be larger than the bore to begin with.

 

I wouldn't use one. If I had a really high compression or were running some kind of boost I would O ring it.

[troyt]

The copper gasket makers like Clark and Hussey will make you a gasket in any desired thickness and bore, a real bonus when you are dialing in a desired compression ratio. Problem is the bore is usually round instead of oval, so you gotta plan around that. For high CRs, a stock gasket sometimes proves to be inadequate. Other than the o-ring option, a MLS gasket is usually the best alternative, but nobody makes one for the L4. I used an MLS on my race L6 and was thinking I could get one of those and trim it down for an L4, anybody ever try that?

 

Copper is soft and grabs onto the head and block surface quite well, but with proper machining of these surfaces prior to assembly, they really aren't required for most purposes.

[datzenmike]

The L4 has an oil drain back hole at the back so you might use the 3,4,5,6 cylinder holes and graft the very front timing chain area on to the front of it???
