Took the truck on its first trip since the new motor was installed.

TD got a data set for the ATT going up the westbound side of Afton Mountain. Going up that grade south of Salem on 81 where the truck lane is was going to get another data set but had a right front tire decided it didn't want to stay in one piece about half way through the run. Had the pleasure of changing a tire on the side of the interstate in the rain at night with a bottle jack that was almost too short.

Pulled back into the house late Sun night and had oil running down the fender of the truck. Started cussing and immediately powered down. Popped the hood and everything had a coat of oil on it. Checked dipstick, no oil visible. Pulled a sample to send off for analysis. Drained oil pan and got about a quart. Filter is in 2wd configuration so it's full. Upon further examination leak appeared to be in oil cooler. Removed oil cooler and drained lines and blew oil out of cooler. After doing this had a total of about 3 quarts of oil remaining in the motor at time of shut down. Never had a drop in oil pressure.

Pressure tested cooler and found a leak between the plates.

Since I still had some oil and never lost pressure I should be in good shape. Anxiously awaiting results of oil analysis as confirmation.
 
With no loss of oil pressure you should be OK. Oil analysis is a good idea. Good luck.

Partner, I am pulling for you. I think your motor will be fine though if you never lost oil pressure.
 
If you didn't lose OP you should be fine. Maybe go for the lube specialist kit. I used it. It came with new OIl cooler plus lines.
 
Ooph... Just said on another thread I have trouble trusting replacement parts lately... If it aint broke, its good lately...

Damn man, I wonder if ya caught a rock there?

Like you said, You caught it before OP was lost, so engien should be perfect (fingers crossed for ya)...

Now your motor is a mess :(

Take a good look at that cooler and let us know the reason for failure please.
 
Cooler was a little over 2 years old. Vendor is warranting the cooler.

There was no obvious damage, ie: rock I'd say it was a weak spot in the manufacturing that finally failed. A simple example of how the cooler is made is one of the old cast iron radiators. This cooler is simply a smaller version of one of them. Picture a leak at the joint between 2 of the sections of the radiator. That's where the failure occurred.

Motor being a mess is an understatement. There is 5 quart of oil slung over then engine compartment, underside of truck and running down the outside of the passenger fender. There is about a cup pooled in the fan shroud.

One thing I plan to do on any other motor that I have the oil pan off of is to install an oil level sensor that is wired to an idiot light and loud noise maker.
 
I'm away from my manuals to know for sure, but I had a thought that possibly just as good to go with a OPS into the turbo supply feed as that may be the most remote bearing to be fed in system I think, and is most critical high speed component needing oil needing maximum oil pressure simpe contact OPS set at X pressure connected to a LED & buzzer alarm........Thoughts ?????

I like the idea. It would also be going off during the WTS cycle. Would make it feel like a big rig w/air pressure. But, that lets you know its working, and you have oil pressure.
 
There is a big difference between an oil level sensor telling you that you are 2-3 quarts low and an oil pressure switch telling you that you have lost so much oil your oil pressure has taken a dump.

My 89 T-bird has a vehicle maintenance module that tells you if you have low washer fluid, coolant, oil and one other level that doesn't come to mind right now. It also tells when it is time for an oil change.

A number of other vehicles use a sensor similar to this one but I haven't had a chance to do any research.

I believe install would entail welding a bung into the oil pan for the sensor then wiring up.

Found this article that explained it better than me. http://www.aircraftextras.com/LowOilSensor.htm

Somewhere in the past, I've a low oil sensor similar to that, except designed to go down the dipstick. Can't recall how it sensed oil level?
