[Healeys] Keeping a Healey, and a hissing oil filler cap

You didn't mention if the normal T fitting for the crank case
breather/valve cover/air filter is used on the top of the valve cover.
Most valve covers with the quick-release style or hinged caps are
aluminum. Many aluminum covers don't have the T fitting. If so this
would account for the excessive pressure in the crankcase. Another
assumption on my part.

Hello Team,

I recently inherited maintenance-duty for my late father's '66 BJ8. By
and
large, it's in good enough condition to just require regular cleaning,
fluid
checks & replacements, lubrication, etc, but I'm just starting to
stumble up
the learning curve as to how to keep the beauty in tip-top shape. The
ridiculous amount of Healey-maintenance literature my father amassed
should
probably help at least a little...

However, recently there has been a hissing sound coming from the
engine, which
builds up slowly after starting the engine, continues while running, and
slowly dissipates after shut-down. I've isolated it to the oil-filler
cap,
which is a quick-release style (opposed to the cable-attached cap), and
pressing down on the cap while the engine's running dampens the sound a
little; oil levels are perfect. My question is what needs to be done
about
this: cap/seal replacement, or could this be a symptom of a deeper
problem
that needs to be checked up on?

Best,
Logan Sailer
