So. . . I blew up my motor

    I was climbing a steep grade in third gear and started losing power. By the time I got to the top the motor was making a lot of noise. Parked and checked it out, sounds like a valve colliding with a piston but not entirely sure. Got towed home and now I am working on pulling the motor. It still runs but it will probably seize if I keep trying to drive it.

    My question is while I have the motor and transmission out is there any maintenance or other repairs that I should be looking for when the engine bay is empty?

    If it were a steep hill maybe the engine was starved for oil in the oil pan.

    There really isn't any maintenance in the motor bay that needs performed. You might wanna change the fuel filter while you have it out though. It's under the intake manifold.

    I don't see how a steep grade could cause the valves to hit the pistons, unless you buried that tach past redline. And even if they did, I don't think it would run after that. usually when a valve hits a piston, something shatters.

    But, if I were taking my heads off, and cost was not a factor, I would consider deglazing the cylinders and installing new pistons. Maybe higher compression ones? Might as well change the spark plugs, coils and plug wires while your in there.

    I agree that climbing a steep grade could not blow up my motor, however my truck has some extenuating circumstances. . . My timing is all messed up because the previous owner swapped the distributor motor into my coil ignition truck with a very jerry rigged job, the camshaft position sensor is not installed which is necessary for proper timing.

    Going to pull the motor/transmission and remove the head to check out the damage. If the pistons look allright at first glance I will probably remove them to check out the rings and make sure the cylinders aren't scored. If everything checks out I will have the head rebuilt and re-install but I have a feeling I am just going to end up having to put another motor in it. I can get a used one with 60,000 miles for $1400 off enginesandtransmissions.com.
