Z22 Metal Head Gasket

[skyy]

Hello

 

I'm after an MLR head gasket to fit an L head onto a Z22 block. Any ideas?

 

thx Rod

Just use a Z22 or Z24 gasket and trim the front around the timing chain off and graft an L series front on. It's not critical as it only has to contain oil splash and fumes. Compare the two gaskets and add any holes needed. They are not exactly the same for water passages. L heads tend to flow more water on the intake/exhaust side to draw away the heat. The Z series are cross flow, so heat from exhaust ports don't matter as the intakes are on the other side.

 

If needing something to contain a turbo have the block O ringed.

But these are conventional cardboard type ones. I'd like an MLR one. But haven't been successful fining one yet😏

 

 

*edit*

I read somewhere about a "expensive Nissan Motorsports 88mm big bore L-series gasket" Do they exist? Or is it a long discounted unicorn?

They (Fel-Pro) are not cardboard but they are composite gaskets and more than capable of doing their job. What is an MLR gasket?

 

Victor Reinz and Fel-Pro both make a MLS gasket. Multi layer steel.

 

 

These are a bit over kill for less than a turbo application. Is that what you plan to run? If so O ring the block to be sure.

 

An LZ22 compression is only 9.84

The MLS type head gasket you are hoping for does not exist... I explored this a few years back building my motor... i though Cometics could make a custom one but can't find that anymore...

My L is around 10.5to1 compression and I'm using a regular head gasket from Victor renez no issues....

MLS is multi layered steel. Not sure what MLR is, maybe a typo?

 

Pretty sure you can still get Cometic to make you something but you have to call them.

Kameari seems to have some if I got it right.. 😎

Seems they do, I only found it for up to 87mm and they say for l16t ... definitely didn't find these 5 years ago....

Exactly what are you planning to use this on? Paying $160 for something that a $30 gasket will do seems excessive.

HKS used to make layered steel head gaskets for L motors. Give them a shout.

 

Otherwise, an OEM type gasket is fine for 90% of engines. Unless it's turbo or 13:1 CR, you don't even need o-rings. But o-ringing the block isn't expensive or hard to do.
