Well guys, I finally hit some bad luck with these engines. I would guess that this one is at least the 30th turbo 3.8 that I have built, and have never had any oiling problems after a rebuild.
So the car had about 4 hours on the engine and about 40 miles of driving. Oil pressure was always at 80 psi cold, 40 psi hot. Took it out to get some pics and on the way home after casual driving, (seriously, casual and no boost), the oil pressure started to drop at idle to around 10 - 15. Made me worry but didnt think too seriously about it since I would be home in about 5 minutes. During part throttle the oil pressure was just fine. Pull it in the driveway and let it idle down, oil pressure goes to 0 !! I thought the gauge was screwed, so I blipped the throttle and BAM BAM BAM!!! Rod started knocking at anything above idle!! WTF!!! This is the first time anything like this has happened to me.
So after a long day, night, and morning, I just dropped the block, crank, and rods off at the machine shop. We noticed that the crank was getting starved for oil?? #6 was gone, #5 didnt have much more to go, and so on.
The shortblock was completely blueprinted, RJC girdle, high pressure oil pump, clevite bearings, std/std crank, stock rods, so the problem is a complete surprise....
So my question is, what can I do when I get everything back on Monday to make sure that this doesnt happen again? Has anyone else had an oil starving problem and what was it from? Any help would be greatly appreciated, cause for the first time I am worried about the oiling system on these things!!
