Omega General Help / Re: Omega 3.2 compression issue
« on: 04 May 2016, 01:02:44 »Results so far aredid you test it when warm? for the 3.2 the compression should be in the range 161-202 psi. If cold probably take off 15psi maybe more so that's 146-187. max 15psi difference between cylinders. harris can tell you all night about wet leaks and where they come from but your figures, coolant loss and the persistent mayo look like a leaking head gasket even though such a thing 'never happens on v6s' . could be something else but those are not good figures. what mileage is it?
number 1 cylinder 113 psi,
number 3 cylinder 110,
number 5 cylinder 160 psi.
Cylinder 2 120 psi
Cylinder 4 100 psi
Cylinder 6 190 psi
Bit of an understatement there - those figures are crap. At best you have failed head gaskets (both banks), or all/any of the other culprits eg broken/worn piston rings, knackered valves, worn/damaged bores etc, on both banks. Despite relatively "low" mileage, fraid its nackered.
Best suggestion is to bin it and fit a replacement engine.
