Thanks for your comments. I had thought of such a diaper pan for my =
situation, until I can remove the transmission and try and fix the =
problem as there is a very large puddle when coming to a halt after =
driving at high speeds for a long distance.
=20
On the same note, my German friend who raced British and European cars =
mentioned that on one occasion in the middle of a race the amount of oil =
had caused the clutch to slip. One of the pit crew suggested that there =
may be a hole in the top of the bell housing so you can pour diesel fuel =
through the hole and flush the oil out off the clutch. The car did have =
such a hole so they were able to keep it in the race. I looked my BJ8 =
does not have a flushing hole in the bell housing, so I must live with a =
slippage in 4th gear for a while.
=20
Meanwhile, PVC system applying negative pressure in the crankcase has =
reduced the leakage to a pint of oil every 100 miles at highway speed of =
60 MPH and above Not acceptable on a new rebuild. Either the =
Archimedes screw is not doing its=E2=80=99 job or the gasket or?

Subject: [Healeys] On the subject of oil leaks and racing
=20
Many years ago, at a panel during a Healey West Coast Meet in Oregon, I =
took the opportunity to ask Geoff Healey about the issue of oil dripping =
out of the hole in the bottom of the bell housing when the car would =
come to a halt after driving a long distance.=20
He gave us the general story that that was actually an intentional =
design feature, with the reverse archimedes screw typically doing its =
job and slinging the oil back in the sump at the rear end of the crank =
shaft. Of course, when the car came to a halt, the oil pressure would =
reverse and some oil would seep into the bell housing. To deal with =
that, there is a hole in the bottom of the bellhousing so the oil =
doesn't pool up. To make sure the hole stays open, a cotter pin is =
placed in the hole, with the legs projecting out the bottom.
=20
But then he chuckled and told the following story. When he and Donald =
were raising street versions of the first Hundreds at Le Mans -- =
generally for the international publicity benefits -- they anticipated =
that the race stewards stationed as observers in each of the pits would =
notice the pool of oil where the car had been sitting when it came in =
for a pit stop, which would have been grounds for disqualification. So =
Roger Menadue fastened small pans, contoured to be fastened under the =
bell housing hole. During the race, the pans would be stuffed with =
diapers, and that would take care of catching the oil for several stops. =
During stops when the steward wasn't looking, a mechanic would pull of a =
filled pan and fasten on a new empty pan. Worked like a charm: no oil =
leaks in the pits and, as we know, the street-spec Healeys, complete =
with bumpers and grilles, finished the race in respectable fashion, =
garnering good publicity and giving rise to the optional "Le Mans kit" =
that was available from DMHCO.
=20
And that's the rest of the story.
