It's been a while since I gave an update...A few of you might remember the problem I was having with foaming oil in my freshly rebuilt 3B motor. Well I can now say I'm cautiously optimistic about the state of my conversion. This past weekend I pulled the oil pan off (hopefully for the last time!), replaced the suction tube with the old one from the 7A, replaced the oil pump, put on a new filter and filled it with 15-40 oil. Despite still getting the oil pressure warning (I'm positive it's an electrical glitch) I nervously let the engine run for about ten minutes - its longest stint to date. Oil pressure on the gauge showed a normal 5 bar, as always then dropped to 3 after a while - normal. Shut it down, waited a minute and checked the oil. To my pleasant surprise, the oil looked normal! No more foam or froth. Now I don't know whether it was the pump, pick up tube, filter, the fact that I let it run for a while or a combination of all of the above. Needless to say, I'm pleased at the outcome. My only hesitation comes from the fact that I didn't like the way the lifters were sounding. More ticking than I think is normal. I could be paranoid of course, but I'd still like to have a mechanic have a listen before I take it for its first boot. Could it be that the lifters still have a bit of air in them and it just might take a while before it's all worked out? A mechanic told me that it sometimes can take 30-40 km's of driving before all the air is worked out of a freshly rebuilt engine.
The other minor worry was that I was starting to see light smoke coming from the exhaust manifold and turbo area. I think I can attribute this to some of the fresh paint heating up and burning off of the exhaust parts and engine block. Anyone else experience this?
Another glitch is that my cooling fan won't come on when it's supposed to. I let the engine get up to about 90c on the gauge and no fan. It proceeded to get to about 105 and still no fan. However, if I turned the climate control to Auto the fan would kick in. Just another thing I need to look into.
