On my 92 300CE.
Just rebuilt the front of the engine with a new oil pump and a everything else (timing chain, oil pump chain, guides, etc, etc..). I primed the oil pump before putting it in and after everything was buttoned up I cranked it over for three 10 second bursts of the starter with no oil pressure build up. Oil filter is new and
DRY.
Anybody have a clue how I can prime this thing while it's in the car?
Thanks

Allen
