[Dauner]

Hi everyone,

Rebuilding my 89 911 3.2 engine.

Looking at my remaining list of tasks before assembling case halves. Is it common practice and mandatory to open up oil pump and inspect / clean internals? I see postings in the forums of sending out for cleaning and/or opening up pump but it is generally people that had a failure of some sort that generated metallic debris, or people with used pumps of unknown origin.

My car and engine seems to have lived a generally happy life, with 212K miles and the only cause for rebuild was excessive oil consumption due to worn valve guides.

My oil pressure was around 1 bar at idle, and peaked out somewhere just under 4 bar on the gauge.

Every oil change I dated and photographed my drain plugs and never documented any metallic content. Only mild traces of sludge.

I'd rather not disassemble if not necessary. Wayne says "clean" it. Not sure exactly what that means.

Thanks,

Mark
