Thread: 2.7L Oil Pump Failures

My D4 2.7 (which is used daily) had the oil pump replaced as a precaution at about 190,000km - due to slow pressure buildup at start. I had my mechanic replace the water pump as well - while he was replacing the radiator (due to a pin hole leak).

After he took out the old oil pump - he said there were loose bolts inside the pump.

With new pump - pressure light goes out almost immediately at start. I now have about 30,000km on this pump and so far, so good.

A week later and no leaks I’m happy to report mission accomplished and oil light does go out appreciably faster. This is third oil pump and second belt change at 266k kms.

Old belt was a ‘14 edition and with no perceptible deterioration. Tensioner was exactly in correct spot.

Even getting the new crank seal over the VR tool was a challenge. There’s no give in those seals. Got that done day 1 so it was able to sit for over 12 hours until eventually start up.

I followed LR Time’s method to prime the dry oil pump from the filter housing turning the engine backwards and it gulped it down. That’s almost an hour in itself.

Not a quick job but rewarding to clean everything out. Brake cleaner and an air nozzle works wonders.

Note in first and second pics the starter motor lower left I could slide forward into this position with main power cable pulled out the way. Was quicker than working out how to remove it.







Thanks for lots of forum support.
