Good chance that your crank is shot, the grinding and knocking and
overheating mean that your rod bearings are gone and you probably spun a
bearing. It's probably too late now since you took it to a shop, your best
bet would have been to dissamble it yourself and let a machine shop
evaluate the componants. At that point you could have decided the cheapest
way to go- a rebuilt unit or rebuilding yours. Having said that I would
caution you about new cam bearings. The normal type that you get from
places like MOSS require line boring, and this is expensive. Cam bearings
don't wear out like rod bearings,(for that matter either does the cam
shaft) chances are you won't need bearings. If you
do, get precision ones they won't need to be line bored. Get the price of
a
rebuilt short block before your mechanic gives you his price. Ask what his
will include then decide how you should go.
