Have you checked your engine oil cooler lines?? Another GMC came thru
my gate the other day and one of the first things I check is the flex
lines between the engine and the radiator. These were so brittle that
the oil was seeping thru the walls. please take a look before you
loose an engine..........Terry

Here's an informative article by another Bob, "Bob the Oil Guy" on how temperature reduces oil's lubrication ability.

Bob,
Where is your oil temp sensor located?

I have been running without the oil cooler for a while now, don't remember exactly how many years. I've found that the oil temp runs
35 to 40 degrees above the water temp and the hottest oil temp I've seen was in the 260's on a 100 degree day (actually 106 degrees
air temp). This past weekend on a beach trip with 85-to-90 degrees air temp the oil was in the 220's. So far my original 455 still
runs fine. I use either Delo 15-40 or Shell 10-30 oil, nothing fancy or expensive, whatever is on sale at Costco. Sometimes a mix of
the two depending on what's in the garage at the time.
That said, I do not tow anything nor do I climb mountains. I live in Florida where it's pretty flat and doesn't get as hot as, say,
Arizona in the summer.
JWID, YMMV. The usual disclaimers. What works for me may not work for you.

Tell him to send J.R. Slaten a bit over a hundred and get a set of braided stainless lines and forget about it.

Although it was written for an air cooled motorcycle engine much of it still applies to our engines.
Note that the charts apply to conventional mineral oil. Use of synthetic oil overcomes much of the oil degradation vs temperature problem Which is why I and many other GMCers use Mobil 1, Amsoil or other synthetic oil.
