Recently my car has been smoking grey/blue BAD upon start up. It starts to smoke after about 2 minutes of warming up and the exhuast pipe is HOT then it burns.... so I assumed some oil was leaking...

I assume this is due to mis-aligned valve guides.. OR oil leaking from the turbo charger and sitting in the exhuast pipe... which I am still trying to source down.

Anyway here are the numbers for my 1978 280Z N47 and N47 head, with that damn turbocharger.. ..

my FSM for my 1978 says it should be between 164psi - 178psi so obviously my rings are a bit worn.. but bad enough to require an immediate overhaul?

Good or Bad?

Cylinder 1 - 130psi

Cylinder 2 - 130psi

Cylinder 3 - 125psi

Cylinder 4 - 130psi

Cylinder 5 - 125psi

Cylinder 6 - 125psi

They are low but the good news is that they are consistant. This means that your engine is tired but it is wearing evenly and properly.
