The car had overheated while idling on an otherwise cool day. A fan on
the cooling system had not worked for ages and this hadn't happened so I
thought maybe the water pump had failed - and it was about due for a
replaced timing belt. I started it up later and it ran fine (smooth,
etc). I did the following:
1) Replaced the plugs - it was long overdue.
2) Replaced the valve cover gasket... starting to seep.
3) Replaced the timing belt.
4) Replaced the failed cooling fan.
5) Replaced the lower timing belt cover - old one cracked trying to put
it back on.
It sat without running for about a month. Started the motor and it ran
rough and at first it made a taping noise like a little oil starved. Now
just runs rough like misfiring.
Plug wires look fine.
I had used the mark near the crank gear. The cam sprocket has both lines
AND a hole that had been lined up. I did take it off to replace the
slightly leaking oil seal, but put it back on and lined it back up
before installing the belt.
I had rotated the motor 2x and the timing marks had stayed in line.
MAYBE the belt is a little tight. NOW I can't see the TDC indicator on
the cover unless I take off the AC belt. By the way, the TDC cover mark
was accurate - when I'd removed the cover the mark on the case was
perfectly aligned too.
So in all likelihood is the problem that I somehow was off by a tooth
on the timing belt?
I need to get this car in good running shape for my son in Chicago who
is starting teacher training this summer (before I move from Dallas to
Tucson, AZ) HELP!
