So I have very recently replaced the RMS, Real oil pan seal, RMS retainer gasket, and PCV valves. Today, I found a very slight leak out the rear.

Is there anything I am missing?

 

there is half moon sort of gasket at the back end of the valve cover that leaks down onto the turbos and you think you are burning up if yo stop at a light after getting it warmed up.
also nice to get more info on the car:
if you would really like answers that would help you and avoid flames give the following info when you post: year of car, n/a or turbo engine, stick or slushbox. Most of us can tell by the year what model you have ie 85T is a turbo z31. Z cars come in many flavors and they are all different. example 84,85,86 Z31's pretty comparable. there were changes in 87,88,89. in addition 300ZX can refer to two completly different cars the Z31 and the Z32. No mindreaders here the more info you can post the more likely you get a cogent useful answer. The cars with L engine (straight six) changed almost yearly from their introduction. A 240Z and and a 280Z have similarities but they can also have wide variance.

 

Fair enough.

'95 Z32 NA 5spd.

 

Hot Z!

Pick up your free factory service manual at XenonZ32.com Reference and check out the other cool docs. You will be impressed with the inspection and troubleshooting pages.

Check out the parts fiche and you might find an exploded diagram of every gasket and seal on your Z. You never know.
