1jz cylinder head help

[NappingMk3]

I searched and couldn't find anything that helped. At the rear of the 1jz cylinder head there is a half moon like piece that sits on the head between the valve covers. What is that called and where can I find one? I've looked at 2jz parts diagrams and I believe it's cylinder head is flat in the back. I think the 240sx ka dual cam head uses a similar piece and I don't know if it would fit correctly

Idk what there specific name is. Just call them half moons. If you went to Toyota and told the parts guy he should know what your talking about.

I would think the 2jz one is the same but idk for sure.

Went to Toyota. According to their diagram the 2jz does not have the semi circle plug. This link shows the differences of the 2 heads. http://www.1jz.com/tech/docs/engine_manual/

I ran the part number online and its only for the 1JZ. I also checked my engine overhaul kit and its not part of that, but there is an online site that can source one from Osaka or Moscow http://quickparter.com/oem-parts/1118388400.html
but you would probably be better off finding one from another 1J.
If you still have yours and it just leaks then throw some FIPG on it.

I'm curious if other half moon's would work on the 1j like from a 5sfe. I seriously would walk in to a dealership (the shop part) and ask the techs if they had some laying around. give them a few bucks for it. When I was at the dealer the techs kept a lot of spare parts like that. A little fipg and you'll be good as new like f00g00 said. (hopefully)

I didn't have any at all, lost while the head was machined. I ended up buying 2 240sx ka plugs from Nissan for a few dollars. I cut 1/8 of an inch off the top because they were a little tall, then added fipg to help seal. Once I finish the car pretty soon I'll let yal know how it holds, no leaks, etc
