<VV> Does diff share oil with PG?

No, the diff and trans don't share oil on PG's.Most likely the oil you saw was gear oil from the yoke seals in the diff. If you tilted the car enough gear oil and trans fluid could leak out of the vents. But you'd also have gas leaking out the carbs too.I'd replace the oil seals for the u-joint yokes. (where the axles come out) then top off the gear oil in the diff.Paul Fox

Main question: Does the LM (or any Corvair) diff share oil with PG? 


The PG does not appear to leak and was OK when I first got the car.


I tilted my '65 110 PG to work on the starter.


Before working the floor was (almost) clean, but when I tilted the driver's
side of car, I have a leak from the inboard rt side strut bolts.


I inspected around the area for the source ~ the big side "nut" on the diff
seems clean, but oil was dripping from the lower strut rod bolt heads while
I pulled the starter out, and pooled a LOT of oil in that short time.


The car has not been driven at all in the last few weeks.


I removed the bolts (without removing the strut rod bracket from the diff)
and cleaned the oil up to let her sit overnight.


Next day, there is no more noticeable oil on the brackets or on the floor.


So, all of the oil leaked out, or the oil level is below the leak?


Any insights I need to figure this out?
