Oil cooling
- Thread starter super diesel
- Start date
looking at past threads of adams from what i remember, there was a 2 week period he awaited testing results for the oil and they came back positive for coolant (not sure how many miles adam put on the truck between then), then how ever much time and miles he put on the truck between getting the sample and finally discovering the oil cooler let go. id think that would be enough time specially loaded but im just guessing
i believe it started here.

I agree there is a good chance that running with coolant in the oil is what caused the bearing issues, but in that thread you linked, he stated the oil pressure he was seeing was normal for his truck.
yup but now hes thinking it wasnt. ill quit answering for him being i wasnt there and see what adam thinks though.
From the time of the sample that was sent.. Till when the pistons failure was ~2400miles. Oil cooler noticeably failed ~350 before the pistons .
This following is a screen shot of my run(video taping stuck VVT) up to Webster Sd back in 4/21/15 ambient was in the low 50s and about 12,000mile before Texas run
This end of March time from first hot day.. Jelico grade is a 7% 6-7mile winding grade on I75 shortly after you cross into Tennessee from Kentucky.. Its 75-80° and roughly 20k miles ago. Grossed 32,000lbs

It's been a long time since I read all the posts in this thread. Does anyone make a bolt on auxiliary oil cooler kit yet that works good? I would like to put one on my lly and lmm.
Be nice of a setup could be used with a recirc pump that would stand up to the high temps drawing oil from the drain on the pan and running it through a large cooler then return from the cooler through the oil fill ..
Wouldn't be cheap.
They make pumps to do it and paired with a setrab cooler and all the hoses fittings and brackets I'm betting at least $1500 for a full bolt in kit.

Anybody have any input on the Mishimoto oil cooler kit?
I was thinking of doing the ppe oil cooler delete bypass and going with something like the mishimoto kit?

I think the cooler needs to be bigger, double in size, but as long as it is in-line and not a bypass system you shouldn't lose any oil pressure and it should work. I like the fact the sandwich adaptor can be gotten with a thermostat. Anyone know if this will work on our trucks?
I had the killer bee kit on my gmc with 66/80 twins and it flat out worked. I paid 975$ for it back in 2012. We need a lot of cooling for the oil because the factory cooler is too small, imho. I want to put an ax cooler on my LBZ but I don't tow heavy as much anymore. Adam, I hate to say it, but if your Gunna continue to hotshot and pull heavy, I think you need to look into a manual 5.9.
Remote mount filter full flow is what i do.. -10 saw and increase in oil pressure over stock due to cooler oil being put in..
Yet to have enough cooling to need a thermostat but I have found these

The killerbee cooler setup I bought off Brian could even be bigger but in reality, we need more cooling from the radiator. The oil is heating it up beyond heat capacity
The stock one works damn well, it's putting so much heat into the radiator, it can't be cooled down fast enough when your pulling hills. The gauges agree cause as you watch them, soon as oil temp hits 230-240*, coolant then starts heating up and keeping a 30-40* temp difference between the two. It happens every time, a/c on or off like clock work.
I'd really like to find a bigger radiator or more efficient one or both after I put the kodiak fan in to see just how much longer oil temps stay down.
That's why I was thinking running no water-to-oil cooler might help but the more I think about, the more I see the oil not being able to stay cool with just the air-to-oil
