When I took it out there are two 1/4 circle rings that fit into the block on I think number 3. There are two gaps on only one side, which way do the gaps face? Thanks

I realized both post are contradictory to one another. Do the two gaps face the crankshaft or do they face the block? If they face each other they are facing the block. Thanks.

The grooves face away from the block....and will face the crankshaft when it is put in place.

Last night when I was looking at it I figured the grooves had to face the crank surface to bring additional oil down onto, otherwise they wouldn't do anything. I wonder what it's doing to the other crank not having them the right way?

I wonder what it's doing to the other crank not having them the right way? I can guarantee you that it is destroying the crank. The thrust bearings have bearing material on one side and steel on the other. It has to absorb the thrust load of the clutch when you push the pedal down. I made the same mistake many years ago on a Mini. Wrecked the special forged race crank in a very short time. Edited by clarkdw, Jun 28 2012, 10:46 AM.

It is possible to very easily change the thrust washers with the engine installed in the car.

Hell though I'll still just pull the engine and put it on the egine stand, I hate doing all that work looking up. Damn! On the bright side I have another crank and thrust bearing sitting around. Does the crank have to come all the way off, or can I just remove the single 3rd main bearing cap and slide it out? Edited by solerpower, Jun 29 2012, 11:53 AM.
