Guys,
Quick question, what is the longevity of a supercharged Previa Oil pump?
I developed an oil leak (about a quarter size) about 2 months ago
Initially I thought it was an O ring from the front of the engine where it connects to the SADS shaft
My mechanic said that it was the Crank shaft seal/ oil pump gasket
He recommends the following
Oil Pump
Oil pump gasket
Crankshaft seal
Oil Filter gasket
Valve Cover Gasket.

I'm not sure if I in deed require an oil pump change as I never had an oil pump change on any of my toyotas.
Sounds severe.
