Made it home on 2 cylindars


Recommended Posts

so yesterday while delivering a pizza, wham, car starts running like crap.  thought I threw a major vacuum line, but upon further inspection both passenger side cylinders were dead.  no change with spark plug wires unplugged.

 

limped it home, no loss of oil or coolant, no smoke (beyond normal), heat was good, oil pressure was good, just running on left bank only.

 

primary suspicion is the passenger timing belt (or associated idlers and pulleys), followed by a possible head gasket or bad intake blow out.

 

will start checking in the morning when I get up, but figured I would throw this out to see if there's any ideas in case its not the timing belt.  you all will probably get up earlier than I do.

well its the belt, shredded the teeth on the crank side.  next question is how easy should the cam on that side turn?  there's 2 spots in it that are really rugged to move, though I would expect that's the part where the springs are tight.  should it be turn able by hand the whole round?  I was using the old belt to turn it, since it wouldn't go by hand.  it moves easy once its near the timing mark to set the belt

I ran it for a about 30 seconds with everything off of the front, no pulleys or covers on it just to make sure it was tracking well.  I dont remember if I reset the tensioner afterwards though, ill have to check.
