Stuart, a large cadre of list members is convinced that the oil foams and overheats, thereby losing pressure and failing to lubricate if it is filled to the mark. One thing I have noticed is that if I fill to the mark, then drive until the coolant temperature gauge is at the LED on the gauge, the oil will be above the dipstick mark. I have not seen foaming, though I have looked for it. That suggests to me that VW meant for the oil to be checked when the engine was at operating temperature, not cold. So, I fill halfway to the top mark, and check it when warmed up, then top it up if needed. Thereafter until I change the oil again, I adhere to the halfway point if checking cold, to the mark if checking at operating temperature. Works for me. mcneely

I’ve never had a problem with slight overfilling in the WBX, but it seems to be something VW is very concerned about. My EVC had extensive warnings about not overfilling the VR-6 engine too. Obviously foaming up the oil with a churning crankshaft is very, very bad, and needs to be avoided. Modern oils have anti-foam additives now though, so I wonder what the real risk is today.

It’s a light solvent oil, and will get past the rings more than motor oil (supposedly cleaning the oil sweep rings too). I just want to be sure people check their oil every 500 mi if they do this, it usually lasted 2000 miles before it was half a quart low.

The '78 production shop rebuild also had piston slap, but that's another issue (crappy aftermarket pistons and cylinders, still the bane of any rebuild).

I've had some relief from using MMO in the past (a quart replacing a quart of oil at oil change, and topping off with oil every 500 miles or so as it burns off), but it could be my imagination. I'll try it with the '85 and see what happens. Shouldn't need to do this with a fresh rebuild though.
