I planned on using a 15W-40 or 15W-50 synthetic oil, but my concern after extensive reading here on BITOG was the fact that these oils tend to be pretty thick at low temperatures. I wanted to be sure I should not be trying something like a 5W-40, not knowing what the impact on oil pressure would be on the high and hot end.

Some of the Olds gurus here will likey nail the problem for you. Excessive bearing clearence is one, too much oil to the top end, worn oil pump (not common). On the pan, more oil will not solve your pressure problem, but is a good idea to prevent oil starvation on hard turns, hard decelleration, etc.

What weight oil are you using? you may want to run some Shell Rotella 15w-40 oil in it. This oil is specified for Diesel, however, it has lots of zinc phosphate in it, as well as a lot of detergents, that can help clean out the crankcase. Using Thick (valvoline #50 or #60 racing oil) is NOT a good idea, for the 455 engine.

olds faq -- buildup

Olds FAQ -- Buildup

People are being misled here. Olds' have an oil volume problem, not pressure. These are two different animals that often get confused. High pressure does nobody any good if there is not any oil to pump. In an Olds motor the oil must be returned to the pan as quickly as possible or the pan may be sucked dry. 40 psi pressure warm is more than enough.
