My bad christhegamer. My first car was a 122S I got from my brother in 1973. He sent me around the west side of Cleveland looking for muffler bearing grease and tail light push rod shims. For some reason this post brought back that memory.

I was sent on my first Boy Scout trip for the left handed smoke shifter.

Chris...how fast is your oil being used? Do you get spots under the car if you sit and idle ?

These cars tend to plug up and develop crankcase pressure if they are neglected by previous owners and it can pop seals that get expensive to replace.

Search forum for " glove test" for a quick check on crankcase pressure.
