Good to know what's normal behavior for the gauge and what isn't. Gives
me another weekend project. As far as the power steering fluid goes, its
full of Pentosin CHF11s. That's one thing Derek made sure to mention
when I purchased the car.
As far as oil consumption, I will probably investigate Derek's idea
about the stem seals/valve guides further, but as I have been looking
around in the engine compartment I noticed a coating of oil on the
bottom of the distributor. Mr. Pulvino mentioned that it may coming
from/through the distributor itself. Once I acquire the Bentley in the
coming weeks I'll have to look closer.
Anyway, thanks for all the replies and the help. Only problem now is
deciding which problem to dedicate this coming weekend to.
