Have compression tested the engine. For some disturbing results!
It was done dry without adding oil to the cylinder to seal any questionable piston ring gaps.

As yet the middle spark plug on the rear bank isnt accepting the 16mm Repco spark plug. The socket isnt slipping over the hexagonal part of the plug?? So off to get a long barrell 16mm socket tomorrow.

The compression test for the front left to right from the camshaft sprocket wheel is 125psi 95psi! and 135 psi
The rear bank is, left to right. 101psi, stubborn plug, 139 psi.

The car has been running as if with a fuel starvation problem or a timing issue. The pluge are a little oily and rich. Not severely so tho.

What cylinder pressures should the engine have?
cheers
