Re: IML: Oil usage theories

["Rob van der Es" <r.vdes@xxxxxxxxxxxxxxx>]

Although I am not an engine expert, with worn valve seals you will have blue 
smoke at acceleration and engine braking (what happens if you suddenly 
release the accelerator at high speed?).

I guess you car is equipped with a PCV system you might check it, maybe the 
valve is stuck. You can clean it with solvent then.

Good luck,

Robert

P.S.: Don't forget: even when our Imperials where new, it was not unusual 
for them to use some oil :)
