help with 92 corolla AE92 (sorta long)

[jgregory]

I had a situation occur about 1 month ago. I was driving home and I heard a small clatter. It was nothing much, then much louder, then whiz, pop, bang, then nothing! What happened was my no. 1 conn. rod bearing spun and disintegrated, then the excessive play between rod and crank made my piston slam the valves (the clatter noise). Then then the rod cap nuts backed off and the cap eventually came off, slamming the rod between the crank and block. This all occured in about an 1/8th of a mile.

I tore the engine down from the top, not knowing what was happening and soon tore into the bottom and found the mess. Luckily no gouges were seen on the crank journals or in the cylinder wall. I even took an emery cloth and went over everything lightly. So I got a new rod assembly from Toyota and have since reinstalled everything. Only problem is it idles great. But during throttle acceleration, there is a real nasty clatter. Sounds like it's coming, of course, from the no. 1 end of the head.

Does anyone have any suggestions where I should go from here?


Thanks in advance.

check the valves. good chance when the piston slammes them may have bent them
