Hi Otmar -

After doing a Eurospec conversion recently I had to prime the pump (by removing one of the plugs at the filter housing and squirting oil down the hole) to get oil to the filter. Frightening. Afterward all was OK, 'til the first oil change when the same thing happened again. Prime the pump and, voila! Q: Are we talking about a gauge here, or light? Has pressure been measured at the engine? If it's a gauge is it a long, long, hose to the gauge, or a transducer at the engine?

When my infamous Eurospec was giving me trouble, it cranked for longer than I was comfortable with, so I hooked up a testlight at the sender to eliminate wiring/gauge as possibilities, still got the same results (light on, wouldn't go out). So I loosened the filter and tried cranking - still no oil. "Oh, ****"! Says I to meself. Thought of major blockages inside the nice new 2.0 engine after days of installation... The first time was with the VW brand oil filter that came with the engine, the second time with a Mann equivalent, both have check valves.

What oil is he using? Could maybe try a heavier grade, or - as an experiment - adding some STP oil treatment to up the viscosity.

Several of you asked about/suggested the check valve in the oil filter. I forgot to say that he claims that he switched to a filter with a check valve in it, but I think that is worth revisiting. I'll tell him to try out a wasserboxer filter.
