My 2.5L grand am had been tapping (lifters) and when I had the valve cover
gasket replaced, and the EGR valve this tapping stopped, temporarily. It
was discovered during the valve cover gasket replacement that 2 lifters were
a bit on the dry side, by bit I mean not totally dry. About 3-4 days later
the tapping began again, but this time it was louder. It was middle of the
week, and on Saturday morning I went to my mechanics home, and left a note
about having him work on the lifters (use a torque wrench, etc to make sure
they were torque to the right numbers). I then returned home. 4-5hrs later
I started up the car, let it warm up about 15mins, its winter here and very
cold outside, backed out of the driveway, and at 2 blocks from the house I
heard one loud clunk, the sound you might here if something metal fell off
and hit the ground, the car immediately died. I tried to start it back up,
and I get nothing but dash lights, the horn works, the radio, etc but no
attempt whatsoever by the car to start. I mean nothing, but the turning of
the key and the dash lights that come on when doing so is all it did. I
lifted the hood, checked the belts, they were fine, battery was okay, and
the car still did nothing. Pushed it home, and now it sits. It was
discovered later that night that the started is barely connected to the car,
bolts or bolt was missing, and when turning the key to start the car a hum
can be heard that I am told is related to the selenoid.

I have been told that to see if the motor is locked up one can try turning
the crankshaft pulley and if it turns the motor isnt locked up. I am also
told that I could have thrown a rod, but that normally it will still start,
or try to if that has happened. I am also told that the starter being not
properly connected could have caused something relating to the fly wheel to
be jammed up or broken which would stop the car from operating. I am
wondering if the car had thrown a rod and that if that was all it did that
it should still try to start. I need to know if that is true or not! Also,
if it has thrown a rod how can you tell? And, any other good advice or
suggestions would be much appreciated!

Thank you all!

first, remove the old starter, take a small crow bar or large screw
driver and try to turn the motor by prying on the teeth of the fly
wheel. te flywheel teeth will not be broken. replace the starter with a
rebuilt unit with celanoid $90, or bench test the old one with jumper
cables. it may have thrown a rod but unlikely. if that taping was a rod
it may run forever that way, but dont count on it. alls yous can do is
check the compresion with the new starter in. you can still have
compresion with a busted rod or piston but it will run realy loud
knocking clattering sound could be mistaken for a tappet (valve) noise
but much more anoying. best thing to do is cange the oil with STP and
run it at a fast idle for an hour. maybe this will break it in. or
blow it up
