Hi,

I understand one of the causes of above problem, could be a blocked crankcase ventilation. However, i am not sure where it is. Any help would be greatly appreciated. Thanks.

It could, but it could be other things too, like a porous flexible section in the downpipe. Put your hand over the exhaust exit(s) and see if the engine keeps running. It it does, a porous flexi is more likely than a blocked PCV.

Needs moving to the Mk2 forum.

Sorry, just realised its in mk1 forum

A Mod/Admin should move it for you

I did put my hand over the exhaust, and engine kept running. Which maybe accounts for smell in cabin, due to leaking exhaust, but not for excessive oil consumption. I took off lid of pcv contol valve, and it was a bit oily. Nothing much there, just a spring.
