I pulled the pump and everything looked fine. I gave it a few light thwacks, threw it back in: 7bar cold start, 5bar hot crusing, 3bar hot idle w/ Rotella T6 5w40 and the 30mm pump.
Owner reviews for oil pump
I went to City VW(local dealership) got new oil pump and had it done. I put 10W30 Mobil. I drove so far only 500 miles and this first oil change I'm going to do with 1000 miles, and from this every 3.000. The thing is that if I had changed only the Oil Pump Pipe, the problem was solved. It was stacked of dirty oil. As the oil pump was out, I though that put already a new oil pump would be more safe.
For a 1.8 8-valve get the oil pump which ends in "D" (93 gas golf) it's a higher volume / pressure pump. the pump will fit the 1.8 engines and the ABA.... the "D" just pushes more oil through the engine which is a very good thing. Better lubrication, better cooling, less lifter niose.
MK3 TDI oil pump, waaay bigger gears mean no oil problems at high rpm
VW oil pump is an excellent design. Starving the pump of oil is the main way to kill it.
final and best upgrade you can do to any vw 1.8 engine (rabbits, cabriolets etc) is upgrade to an 2.0 oil pump (just ask for an 95 vw jetta or golf 2.0 oil pump) it bolts right on is about $60 from any autoparts increases oil pumping volume dramatically and will keep your engine alive for years to come.
The pump looks to be too beat up to keep. Even though I could maybe drimmel the bad spots down, I'm just going to get a fresh pump.
The oil pump pick up screen separated from the seal due to debris built up and a piece of metal from one of the chain guides got through and froze the pump gears.
