I want to put a fresh engine gasket set on my L20b in a 1970 Fairlady Z. I know the bore is smaller, but how about the block height? If it is the same height as the L24 then I should be ok on the front cover gasket.

Anyone with an L20 engine ever put new gaskets on? Is there actually an L20 gasket set available?

Hello atleast here in finlan basic l20 engine is quite common. We have lots of Nissan Laurels with that engine. I think that the Nissan has gasgets.

1998cc L20A 81--84 6-syl. . . . . . . . . . . . . . . . . . 27-4361 62.90

That's whole gasget set for l20 in one Finnish company. Price is euros. Euro is allmost 1to1 with dollar. Including all engine gaskets.

Plain head gasget is 19 Euro.

Bleachzee,

Please be careful not to mis-describe your engine when ordering gaskets. You mentioned "L20b" above - which is a four-cylinder engine................

Gaskets and ALL parts for the L20 are still available from Nissan Japan, and there are hundreds of thousands of cars running around in Japan which are still using the L20 six. Just make sure that your parts supplier orders the parts for the right engine.

Block height is the same as the twin-carbed L24 / L26 / L28 engines - so all gaskets other than the head gasket will interchange.

Good luck,

I even reckon an L24 head gasket would work. After all the L20A has notches in the bores to allow the valves to clear. The valves would probably be the same as the early L24's too (42mm & 33mm). Don't quote me on that though... I only have an L20A crank, rods & pistons handy, no block or head.

Ok, thanks. I wasn't sure how many of these engines were still around.

and yes, I accidently hit the "b" I guess I'm used to typing the L20b engine code too as I have a Datsun truck also.

One question,

Are you the same guy that had the "bleached" pages on the 620 restoration...dark blue in color?

Just curious. I had a 72 1/2 I was going to restore but was a little too late to make it worth it. Had the ol' 1600 in it.

Nate:cross-eye

yup, that's me. Still undergoing that project along with my other Datsuns.
