Tom,
Sounds like it might be valve guide seals. If you're tricky you can
change them without taking the engine apart.

Hi to the list,
I wanted to query the roadster experts out there on a recommendation for the
best weight oil for a U20 that is puffing blue smoke on take off. I have
long suspected either the valve guides and seals or rings have wear but doing
a
wet and dry compression check shows hardly a difference in compression. The
car is running so good that I don't want to take it apart quite yet. I have
been running Castrol 20/50 for they claim to control oil burn off. Is this the
best for my situation or is there a straight weight I could be running?
Thanks,
Tom 69/2.0
