Re: spun bearing question
oil pressure at start... then after warmup your light comes on. if you catch a bad bearing early enough you can replace them. ive heard stories but never had any experience with it.... wouldnt bother with it
i do know however if you heard the rod slapping the crank its f'ed.

Re: spun bearing question
Dropping the pan isn't all that hard, nor time consuming. What are your suspicions of a spun bearing? Drain your oil, see if there are any metal shavings in it. If there is, that's a good hint to a spun bearing.

Re: spun bearing question
Rod knock caused by a bad bearing will usually be accompanied by a, well grab your chair, a knocking sound which is typically louder upon startup/before warm-up, then get progressively quieter, typically getting even more quieter under higher RPM's (though of course the knocking gets faster). When this happens you can almost bet your crank is screwed, hopefully not beyond the point of having it turned down and polished.
Drain your oil into a CLEAN container (as in drained and even wiped down), drop your pan, take a magnetic screw grabber (it's a magnet on a telescoping "pen") and fish around first in the container you drained the oil in and then the oil pan itself after inspecting the magnet to see if there is metal from the container.

Really...? You're too lazy to type in a manner to suggest that you're not ignorant, I have serious doubts you'll spend some time to look into the situation.
