yeh, I really screwed up. Last summer I was rerunning my remote oil filter lines and when re-installing them I reversed the lines. I have 2 oil gauges, one under the dash, and one on the oil filer base under the hood. When I re-started the engine, I had no oil press. on the gauge inside the car, but 60 on the one on the filter base. Stupidly I drove the car a couple of doors down the street and back thinking the gauge inside must be screwed up. After I corrected the lines, instead of the op (oil press.) being 60, it was around 40 running and barely 30 idling. And the thing vibrated bad. So I thought the driveline was bad, corrected an inbalanced driveshaft but it still vibrated. Rear end was just rebuilt as was the tranny. New ujoints too. New yoke. I re did the carb, and probably put a couple of hundred miles on it trying to get the vibration out, even jumping into it a couple of times through all 4 gears at 6500 rpm. Still it vibrated and seemed to be doggy. But it only vibrated and never knocked or rattled any.
Well I just pulled the motor and found shavings (looks like mostly bearing metal) in the pan and stuck on the oil pump pickup screen. The rod bearings look ok. But I spun one main bearing, but the journal looks good. Cannot feel any grooves although it looks scarred a tiny bit. The rear main bearing looks good but I can feel a tiny groove in that journal though. All the bearings look a bit like they had been sandpapered but the crank journals all felt smooth except for the one I mentioned.
Also, there was a black, tar like, sticky substance on the pickup screen. I had to scrape it off with a knife. Looking down into the block, a couple of the lobes on the cam look dark on the outside edge of the lobe, not where the lifter sat on it. From what I can see of the cyl walls, they all look fine. Hopefully I can save all the hard parts and just replace rings, bearings, have it re-balanced, but am not too sure if I need it re-blueprinted or not. So because of my major brainfart, it looks like a major rebuild although nothing broke, at least. But I still cannot believe that nothing came apart after my f.u., nothing knocked, even after some thrashing.
ok, so let me have it (covers head to protect himself) http://www.nastyz28.com/ubb/redface.gif
Any tips I need to remember, besides putting the hoses back on the right way?
