Repair Questions and Answers

Question: 1987 Plymouth Colt 1.5 Liter
mileage: 134,000. My wife has an 87 Plymouth Colt. We
were on a trip when the valves started knocking really
loud. We pulled over immediately and shut it down, and
added some oil, when I tried to restart it; it ran for
about 5 seconds then died. After a LONG tow, I am trying
to find the problem. I removed the valve cover, rocker
arms and timing belt, camshaft turns smoothly. The
crankshaft will turn easily about 3/4 turn then locks
tight. The car has never burned or leaked oil, but the
oil light stays on. I checked the oil regularly and used
synthetic thinking it would prolong the car's life. I am
thinking a broken connecting rod, but I'm a carpenter
not a mechanic. Any advice?
Answer: You are right; you did break
a connecting rod. Unfortunately a new motor is your only
remedy.
Question: 1990
Plymouth Colt 1.5, mileage: 115,000. It looks like the
back wheels are locked up. Cannot drive backwards and
driving forward produces smoke and loud squealing
noises. Is this a problem with the brakes locking up or
could it be the back axle?
Answer: Remove
the rear wheels and brake drums and inspect. We think
that the brakes are locking up.
Question: 1989 Plymouth Colt
1.5 mileage: 51,000. Where to locate
the ECU & air flow meter.
Answer: The ECM
either is located under the right side of the dash or
under the front seat. The air flow meter is under
the hood and it is connected to the intake system.
