Oil Cooler.

[chevymaher]

I pulled it. New front and rear seal. Laid under it and scrubbed it from end to end. I bought a electric motor to a drill press and rebuilt the crankcase vac pump. GM's equipment isnt made for continuous duty and they eat the electric motor brushes. This one is ball bearing on the shaft and a cooling fan. 10,000 rpm so it sounds like a jet engine spinning 3x what it was.

I added a oil catch can.

Waxed and cleaned her, Waiting fora decent day to go out again,
