Putting 85 om617 in a74 ford f100. I'll be using the f100 radiator. Do I need to rig up an oil cooler? We live in western oregon and temperature seldom gets in the 90's.

Along the same line would you put in a intercooler with the turbo?

Thanks for your help
Greg

If you plan on towing yes! Also if you plan on towing you'll need a transmission cooler as well.

If you're just doing everyday driving probably not.

Don't forget to grease the screw and threads on the spring compressor.

I would go with some sort of Oil Cooler. Because Oil squirts up into the piston heads to cool them.

However you did not say if you were retaining the Stock Oil Filter Housing which of course has a thermostat.

If there is no room some have remotely mounted the stock filter or simply made a plate to replace the Oil Filter and added another type of Oil filter.

In the fist pic the shorter the hoses are the better and the adapter plates in the pic are rather thin and crude. The Oil Cooler hoses are not shown.

In the next pic is a thick adapter plate that is treaded for fittings.

I'd try to include the cooler. We did on my 39 Studebaker. We used the stock radiator and stock oil cooler. If you are increasing the power a lot an intercooler might be called for, if not it wouldn't help.

The oil is sucking heat out of the turbo bearing area. That turbo will get almost red hot sometimes. So on the turbo engine I would get an oil cooler in the fan stream. It is thermostatically controlled as well.

Keeping the oil temperature down probably keeps the viscosity of the oil up better. This is a diesel so it has high thrust loadings. I am not certain as mentioned that spraying the bottom of the pistons generates that much more heat as well. Yet it could be.

Oil is actually part of the cooling system for engines as well. Or at least it gets moved around to places it can dump some heat even in normal engines.

Howdy neighbor, western Oregon resident myself. Unless you're right on the coast, we spent I think a month with every day reaching over 90 last year, and several topping 100?

The turbo is oil cooled, the pistons are oil cooled. In a car application, which is a much lighter duty cycle than a truck, Mercedes chose to add an pretty serious oil cooler.

In a truck application, where you may be at WOT for minutes at a time dragging a load up a hill, I wouldn't consider running without an oil cooler.

If you're going to stay at stock power levels, an intercooler isn't needed.

Here's my experience. I'm admitting up front that my situation is pretty case-specific as I ONLY do Land Speed Racing (LSR) on a 1 mile paved track. But here's what I've done and how it works for me.



1) I do not run an oil cooler. Nearly all engine operation is at full rack with the engine doing all the work it can do. My last dyno run showed in excess of 225 HP and I'm probably running more than that now as I've added boost since that run. So I'm potentially putting a LOT more heat into the oil but for a relatively short period of time. It it isn't a chore to install an oil cooler it's probably cheap insurance though I get away without one. IIRC, my max oil temp has been about 200F and drops quickly when I back off the accelerator at the end of the run. The lack of oil cooler was primarily a result of packaging issues arising from cramming an OM617 into an S-10 pickup (it's a tight fit!).



2) I'm running a water-to-air intercooler with ice water. It makes a BIG difference in top speed and therefore, HP. I screwed up and forgot to bring ice for the first run of the day at one meet last year but ran anyway. Instead of a top speed in the area of 130ish (best speed so far is 136.2) I ran like a 119ish (I'm pulling these speeds out of my fuzzy ol' memory). My max intake temp is about 90F at the end of the track instead of well over 225F w/o intercooler (depends on ambient conditions). So yes, an intercooler is a good thing. Again, I'd think carefully about how much effort it will take to build one into the system and do so if you can fit it in. I got my intercooler from Silicone Intake Systems (Google them) and it was surprisingly cheap. I use a picnic cooler for the ice water and a bilge pump to move the ice water around but that probably won't be a solution for you. Maybe ait-to-air might be better for your application.
