I think you hit the nail on the head Glenn.
I was driving about 60 and I was towing my M-101 trailer with a few hundred
pounds. I have gone over the Sierras a few times before but never with the
trailer. My temperature was bouncing between 200 and 217. When it reaches
217 the fan kick in and drops to 200 but with in 5 minutes or so the fan is
kicking in again.
Thinking of temperatures, what is the normal operating temperature for a
HMMWV? In my vehicle if I drive flat and level at 55 it stays around
200~210. If I drive faster or go over hills it rises to 217 and the fan
kicks in but I've never seen it go over 220. I know the danger limit is
230.
One other thing, the oil I was using was 15-40 Delco 400.
Anyway, the next time I tow the M-101 over the mountain do you recommend an
precautions that I should take.
Thanks a lot Glenn, I feel better.
Darrell

Hi Darrell
That would be perfectly expected since the engine had been working under
heavy load for a while and your temp was probably above 190 or so also. The
oil was just breaking down under the load and heat. Your readings were
still well within spec. 60 is actually on the high side for a Detroit 6.2
anyway with a warmed up engine. You can expect the conditions you saw when
towing a heavy trailer or climbing mountain grades, or running at approx 60
in a Humvee for a while on the highway.

Subject: [MV] Mystery oil pressure problem
Mystery
Gents
I drove my HMMWV this last weekend from the San Francisco Bay Area to Reno
and back. On my trip I experience an unusual oil pressure problem that I
hope some of you Diesel Engine Experts can help me with.
Friday night I drove out to Reno. As I was crossing the Sierra Mountains at
about 4,500 altitude my oil pressure dropped about 15 psi. Normally when I
drive it's at 60 psi & 30 psi when idle. So now it was at 45 psi. I
stopped at a Rest Area and check for leaks and the oil and everything was
fine. I also tested the engine. When I stepped on the gas the oil pressure
went up then dropped when I let of the gas. I asked a trucker at the stop
for some advice. After he check things out he said I should be okay. As I
continued the oil pressure reading dropped to 30 psi but the engine seemed
to be running fine. By this time I had reached the summit and since the rest
was down hill I decided to continue on. As I started going down hill the
oil pressure went up to about 40 psi and stayed there. I finally made it to
my destination with no problems.
I discussed the problem with some friends in Reno and they felt I should be
able to drive home. So I drove back to the Bay Area today and my oil
pressure was normal all the way home (60 psi driving & 30 psi idle). In
fact it ran just fine.
The only other thing I noticed was that there appeared to be some oil
residue around where the exhaust manifold attached to the block but it was
just in one spot and I could tell it this was fresh or not.
So my thoughts now is that perhaps I might had a fluke with the oil pressure
sender unit or gage is going bad. But the oil residue around one of the
exhaust manifold and engine block concerns me. Maybe the gasket has a small
leak or it's something else and if it does I don't know if it's related. So
if anyone can help me solve my dilemma I'd appreciate it.
Thanks
Darrell
