Subject: Re: Oil consumption and more questions


Gregor, oil consumption can have three causes:

The o-rings arround valve tail worn out. Moderatly easy to fix. Need to
remove cylinder head.

Cylinder, piston and rings worn out. Harder/more expensive to fix. Need to
remove cylinder head, change piston and rings and ream the cylinder (bore
it larger than it is). This is the more common cause. Requires run-in. If
you do it, also check valves and change their o-rings.

Cylinder head gasket broken. The oil goes into the water. Very easy to
check: open the radiator (when cold!!) and see if oil floats above water.

Finally, do not forget oil leakage!!

Pierre
