engine oil runs HOT

[kyle6241]

My oil brakes down in about 1000 mile and messes up the computer
so far we have determend the oil is running hotter then it should be
we sent in an oil sample and everything check out normal.
I am looking to clean the oil cooler and need help on how to get it off etc.
unless someone else has a better solution.

how hot is it running? what kind of oil are you running?is ther any fuel in the oil?

[ianstew]

yeah, how hot is the oil running,and what problems led you to the hotter than normala oil diagnosis?

Thankyou for the questions and I will be gone most of today and will answer any questions as soon as I can get to the email.

The oil runs at abouit 230 to 240 no load
I pull a 30 ' stock trailer and haul any where from 12000 to 18000# and loaded going up hill the temperature will run up to 280° and I been told the oil tem should not run much more than 15° higher then the water temp. the turbo temp runs from 1000° to 1200° depending on the pull

Last fall I started having all kind of problems with engine running poorly and the check engine light would come on and nobody could tell me what was wrong and then I got to noticing that every time I changed oil the engine would run NORMAL untill I had about 1000 miles or so on it and then the same problem so I would change oil again and same thing it would run normal for a while
I was told it much either be antifreez or fuel in the oil or heat to brake the oil down so I had the oil sampled and there was no antifreez or fuel in the oil so I put a heat gage on the engine oil and it shows it is running warmer than normal.

I have tryed 3 different kinds of oil. Rotella and Motorcraft and the cheapest oil I could find at our local farm store all 3 oils was a diecel 15/40 oil. I have a long story to tell about each oil will save that till later............... morel of story is ALL 3 oils do the same thing The only way I can explain it is it messess up the computer and thing are not right.
I bought the 1997 f350 with 112000 miles on it and the first 100000 no problems it now has 240000 on it and it only will us about a QT of oil in 2000 miles I am not ready to get rid of it but I sure wish it work like it did before.

I'm hoping that turbo temp is with the EGT probe in the manifold
It's not messing up the computer, but the sensors are telling the PCM something is wrong. And with the oil broken down so bad, it is probably just wreaking havoc with your HEUI system.
Those oil temps. Is that with an aftermarket gauge or what?

[kyle6241]

The gage is an electrical gage with sending unit in the block oil port and the gage in the cab.

The turbo temp is from a high price turbo temp gage that was bought and installed in the exaust just after the turbo I put that in severl years ago.

I would check your oil cooler
my water temp runs 195-200 and oil temp 200-210
with heavy loads wt 200-210 ot 210-220
not sure at what temp, but when the comp sees to high a temp it gose to limp mode.

what if any mods do you have and what is your wt running?

how long since you changed your coolant
do you have an intercooler (since your egts are so high) is 1000-1200 just when climbing hills or a steady temp ??

[kyle6241]

Thankyou
That sound much more normal.
I called and got a mechanic lined up to take off the oil cooler the first of the week.
do know if the old one can be cleaned or do we have to buy a new one?

running wt is from 24000 to 32000#
The computer was set to factory spects about a yr ago. I have no add on's
I have not changed the coolent it looks very very clean etc. How ever that may be a good ida.
my turbo gage runs on the flat 900 to 1000° climbing then it runs arouind 1100° and a big long hill it will be up next to the 1200°
