Question about 1990 Nissan 300ZX
Engine oil go troungh in manifold ,how to fix it
I worked in a Nissan dealership for 10 years...
I've seen these gaskets dry out and get hard over time- like enough that you have to chisel them off of the valve covers! That's most likely the source and you'll have to pull the plenum to get the valve covers off... 20+ hour job for an experienced tech... Good luck!
