Nickanicus Posted January 27, 2010 Share Posted January 27, 2010 Hey guys, I'm in the process of replacing the valve stem seals on my 75' 280Z L28E and I found out that the motor has double valve springs installed on it. To my knowledge, the engine is stock. Did these motors ever come with a dual valve spring setup? Also, I'm doing this job with the head on the car, and I ended up making my own valve spring compressor. Does anyone know of a valve spring compressor that will work with the cam still installed? Thanks, -Nick Quote Link to comment Share on other sites More sharing options...
Xnke Posted January 27, 2010 Share Posted January 27, 2010 Nick, they all have double valve springs stock; and there are quite a few spring compressors for OHC engines out there. Do you have the How To Rebuilt Your Datsun/Nissan OHC Engine, by Tom Monroe? It's a great reference and has all the part numbers, diagrams, and information that the other books leave out.

Nickanicus Posted January 27, 2010 Author Share Posted January 27, 2010 Ah, cool, that makes sense then. I don't have the book, but I'll look on Amazon. I'm just doing a quick freshening up of the motor for now. Eventually, I want to rebuild the head with a hotter cam and all new parts.
