Are you sure it was a VW reman? There will be yellow sticker on top of the case if it is. The serial # will be ground off the case and a new one is usually on the tag. Assuming you are using the correct viscosity oil and the oil cooler is doing its job, the most likely cause of low oil pressure is loose bearings in the case. Most re-builders do not align bore these cases. These cases also warp and twist causing all sorts of problems including blown top cylinder gaskets. If it runs well with no noises, make sure you really have an oil pressure problem before taking it a part. You need to measure the pressure at various oil temperatures. If the oil reaches 250F, the pressure will be low. Ideally, 10 psi/1,000 rpm is good. A hot engine will be somewhat less. Dennis

The engine is a newer VW reman (30,000 miles). After searching the archives it looks like bad rod bearings are the most likely culprit. I think I may take the plunge and try to correct this on my own. My question: It appears that after removing the heads and jugs I can change out the rod bearings without splitting case. Is there any chance this will take care of the problem, or is it nearly guarnteed that the crankshaft will need to be removed and machined? Thanks, Jake B
