Got that pre-lubin' feeling
Those of you who kindly responded to my engine pre-lube question, thank
you for the many and varried ideas. In the end, what ended up working
was dropping the sub-frame, removing the pan, attaching a long hose
directly to the oil pump inlet, raising the other end of the hose higher
than the feed line, dumping in tons of oil, and spinning the engine (via
starter motor) until oil was flying from every exposed orifice. A handy
wine bottle cork was the perfect size to temporarily prevent oil from
draining back out of the pickup after the hose got yanked and the pan was
being prepped for re-installation. Just to be anal, before I put the pan
back on, I filled it with 4.5 quarts of oil so the pickup would be under
oil at all times (don't think this step was really necessary, but you
know.... Lesson learned: The best way to an Audi oil pump's heart is
through it's main artery. This sounds like a lot of work, but it's
reallynot all that bad - about 2 1/2 hours. If I had done this in the
first place, it would have saved days of frustration.
Things that didn't work:
1) Over-filling the pan by 1.5 quarts (didn't really wanna go much higher
than that.
2) Jacking rear end of car up and letting sit overnight.
3) Trying to back-fill the oil passages by pouring oil into the pressure
sender hole and/or the turbo oil feed line.
4) Any and all combinations of the above that you can think of (believe
me, I tried them all!) but your mileage may varry.
Note: all priming attempts took place with both oil filters pre-filled and
with a fully charged battery.
