While using my XM215 Dump Truck yesterday for a goodwill gesture I heard a bang followed by a strong vibration and an intermittent hammer noise. At first, I thought I dropped a valve. The solid vibration/miss combined with the occasional hammer/bang noise puzzled me. After I dropped my load (was loaded heavy), I left it idle for a bit. As it sat there, when it hammered, the stack puffed the pretties blue smoke you ever saw ):
After limping it back out of the woods to the shop (nearly 3 miles) we proceded to check it out. Pulled the valve cover, valve train all looked good. Pulled the plugs for a compression check, #1 completely dead, other 5 right around 100-110. Upon further inspection, I could see the top of #1 piston...it didn't move when cranking. :(
Dropped the pan...bottom of the piston laying in the oil pan. Seems the lower half of the piston gave up the ghost...right above the wrist pin. So, there was the rod just slapping up and down in #1 hole! I can't tell you how bad the cylinder wall looks...there has to be 1/8" deep groves in the cylinder wall!
So, at this point, I'm looking for a GMC inline 302. I would prefer to find it with the trans bolted to it. I'm not so fussy about whether the engine/trans is ready to use, cause I'm gonna take it apart for a rebuild anyway. I don't have a problem paying to have the thing shipped, either.
Anyway, as many of you know, I'm located in North Central Ohio. Anyone got an engine for sale?
