sludge in crankcase

[tjstahly]

So its been a while since I've been on this forum but I'm kinda puzzled.
I built a G-2 last year from ground up. When I rebuilt the engine I used factory parts as in rod bearings piston rings valves and gaskets. I also replaced the roller bearings for the crank. I put plowmans advance key in it and jetted the carb and put a KN filter on it.I lifted it with Jakes 6 inch kit and put 10" 22s (tires) if my memory serves me. I was never really impressed with it even though I could get 23-25 mph out of it with the govonor removed. It always seemed to vibrate to much even in neutral. I also have a stock G2 that is smooth as could be.This is my reliable one that I use to compare all my additions to.So with all that said this weekend I drove the lifted one and it just kept getting slower and slower like it was over heating so I parked it. Its always been my thought that I got the balance shaft off(out of time) ( my vibration problem) so I pulled out the eng and took it home to see what i could see. I disassembled it today and when I pulled off the side cover much to my suprise it was not out of time but there is a lot of sludge in the crank case,slivery kind of sludge. The engine probably only has 10 hours on it. It stays in a camp ground in Northern Calif. I pulled the rod bearing and its is fine.Tomorrow I will reluctantly pull off the cyl head and check the piston and cyl wall.The piston was the stock size so I could always go 50 over if need be. I have been a mechanic ( technician) for 30 years so my pride is slightly wounded but only a little bit. Any help would be greatly appreciated . Thanks in advance Tom
