Overfilled Oil

A little bit won't hurt but,,,, if it is way over full your crankshaft will
have to fight it's way through the oil so your mileage and power will
suffer. I lost a fuelpump diaphram on a 327 once and filled the crankcase
with gas. Had one hell of a leak, out the dipstick, oil filler cap, blew pcv
out. Sure smoked a lot too.

How far (in inches) over the full mark is it?

Thanks for the quick reply. The engine sounds/runs normal (i.e. great) and
the tailpipe emissions are normal (clear). I love the 4.3 Vortec...just
wanted to make sure nothing damages my "baby". haha

I didn't measure it but its past the FULL mark...but not so far as to ride
up the stem of the dipstick.

Ok, there is about 2 FEET of dipstick above the full mark. GUESTIMATE how
far over the full mark the oil level is. 1/2" is a lot different than 2".

So what's the problem? If it is over filled, either do it
yourself, take you vehicle to a shop, remove the oil, refill with
the proper amount of oil, end of problem.

All the above said if the oil is too high it will be turned to foam by the
crankshaft and the bearings will be starved of oil and burn up. If it is
more than 1/2 inch above full drain it and fill correctly...
