Tonight I was pulling the oil pan off of a car we were working on to find four pieces of what used to be a thrust washer. I was actually only pulling the oil pan because it was warped and leaking around the gasket. Of course once I found the thrust washer in pieces I went ahead to pull the oil pick up, windage and #4 main. To find what was left of the opposing sides thrust washer.. There wasn't much left it was ground down to about half. the thrust washer that wondered out of place obviously got flug around a bit as the under sides of the pistons ar a bit nicked up. The sleeves appear fine and other then that there are some scrapes on the counter balences (3 and 4). I will try to get some pics in a few days if anyone wants to see. I'm not really sure what would cause this but I have to ideas which are over reving and the motor not being align honed prior to assembly. The motor was assembled by a knowledgable person and I don't know how he could have caused the problem. I searched and found a prior occurance but it was a stock motor.. which this on the other hand is a B20 vtec with weisco pistons,eagle rods and a greddy turbo kit. Anyone had this problem? I have a feeling this guy will want us to just put some thew thrust washers in and let it go.. I have a feeling thats exactly what one of the rods will decide to do as well. One more thing is that the car also had a broken gear selecter within the tranny.. whatever that thing is tegnically called I don't know.. I am talking about the piece that selects the gears with the forks and is controlled by the linkage. I guess it's possible these two aren't related. The car still ran quiet..
