started it to drive it on the trailer to
get it to a mechanic and left it run on
the way there probably ran 30 mins
to 45 mins and later found out it was
the oil pump my question is with it
running that much time with out oil
should i spend the money to get a
new motor or just replace the oil
pump?? Will start up and you can
hear and knocking or anything
sounds fine just don't know what j
should do please help

If it's not knocking, ticking, or smoking you should be ok to replace the oil pump and be on your way. HTH. -Jim
