<x-charset iso-8859-1>You know, this is exactly the same problem that I have with my motor and have yet to find a way to correct it. In fact, I've been driving it for 4 months and over 3,000 miles like this (with next to no oil pressure and the oil light on at idle). Anyone have any other ideas I can try? It is looking more and more like it is bearing clearances. Should I change to a 40 or 50 weight oil to squeeze a few more miles out of this motor? Or would that be too thick an oil and cause the bearings to starve for oil before the engine warms up? Thanks!

What have you done to deal with the cooling air problems of a type 1 engine in a type 3 body? > I was running a melling 30mm pump with a gene Berg pressure relief valve to an > external oil filter and cooler. Do the Melling pumps still have an iron body? If so, these have a known problem with the fact that they expand less than the case and tend to leak at the junction. I don't know how much of an oil pressure problem this would make, but it contributes something. Still, a 30mm pump is HUGE and is likely to be able to overwhelm almost any flaw. > 1) Had to removed the Berg Oil pressure relief cover and have it polished until it was > smooth. It may have been allright but was too rough for my liking. Just the face? Was it leaking there? Like you say, it was probably fine. The Blanchard ground finish on these certainly looks a bit rough, but they've worked fine (as in no leaks) for me. I suspect that a certain amount of surface roughness is important there to keep a gasket from migrating away in time. I really don't know what it should be, but rather coarsely finished sealing surfaces are common here and seem to work. I would avoid a highly polished finish. > 2) The Berg Oil Pressure Relief cover had been incorrectly assembled at their factory. > A second hand washer of the wrong size was used which pinched and ripped the sealing o- > ring and washer. I had it dismantled and reassembled with correct sized washers. Did this just make it leak, or do you think that it made the relief valve trip prematurely? This doesn't seem consistent with getting 80 psi at idle. I also don't see how this might cause a temp dependent problem, which was your original symptom. Little things like this are both hard and disappointing to find, especially so when they come from Berg. While I'm pleased that you seem to have your problems solved, I've got to wonder if there is still a cooling system problem, since that's what your symptoms seem to point to. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- Unsubscribe? mailto:type3-request@vwtype3.org, Subject: unsubscribe </x-charset>
