Thanks Harvey - I don't know when I'll get the chance to dive into this - I promised the missus I'd put some hours in on her Mk2 Cortina......that's been waiting for paint for 6 years....ooops....
They all seem very low, what sort of state is the starter and battery in? Throttle fully open?Most are around 105-110psi but #4 and #6 are 84 and 92 respectively. I'm hoping there's an outside chance that a gasket failure has resulted in both dropping, and pressurising the valley or sump at the same time........These are on the drivers side, which is also the side leaking.
i recently did a compression test on a 10.5 engine prior to doing a cam swap, clearly it was healthy as all 8 cylinders were between 165 and 175psi175 psi min for 10.5:1 according to the WM.
Seeing they are all so low I’d worry more about the validity of the comp test. It seems off.Riiiiight. That sounds like there's a problem with the whole thing...It's supposed to be only 30K old, so I wonder if it was rebuilt with poor ring end gaps or something. Well -no point in band-aiding it. I guess she gets parked-up until the Cortina's done and then a full rebuild.......bugger.
