Oil Cooler issues

[jdchristian3]

my wife's oil cooler recently started leaking oil to the outside. she noticed it and drove straight home. it was a purty good leak... called ford. said bring it in, its not an oil cooler. i said OK. turned out i was right. they then said with the leak it has there is no possible way the water got in the oil. took an oil sample, but still waiting on the results. i say, according to the blow apart diagram i got, the it most likely leak water into the oil. any insight is helpful. THANKS A BUNCH!

in my experiance, all have leaked externally, with no swapping of the fluids.

Mine also leaked externally. Usually when the orings get bad enough the oil will leak into the cooling system and radiator.

From my experience the coolers not that hard to do and it would be a lot cheaper then going to the dealership.

When you get your new seal rings, be sure to also pick up the gasket that connects the front header to the timing cover!

There are just 2 bolts that connect it and in the long run----it is better to just remove the entire assy as a whole, as opposed to attempting to lever the cooler core into the front header while still attached to the timing cover.

Looking back....methinks for certain that is what caused my timing cover failure and engine removal

thats possible but we got ya up and running again fairly quick


i doubt it mixed the fluids as well.mines was leaking only when cold.set of new oring and gaskets and all was fine with no fluid mixture happening.take it out as one unit and put it back in as 1 unit.as geo said thats probably how he cracked his timing cover.the end caps are a PITA to get back onto the core with new orings.i use a wreckers boom to pop the ends back on,thats how tough it is to get it back together.

Mine wasnt to bad to get back together, I bolted the front header on and used a prybar and a 2x4 to push the bundle and rear header into the front header. No leaks as of yet, I used the exhaust pipes for a little leverage and it popped together fairly easily with a little assistance.

getting the Oil Cooler back together

I used a pipe clamp, Like you would use to Glue Lumber together.

Worked Awsom.....

DO NOT DO IT THIS WAY!!!!!!!!!!! as geo said that is probably how he cracked his timing cover

The PSD are a little different than the IDI, but this is how I did mine on the IDI's. Just posted on the IDI forum for the same fix. Go there and read it.

The IDI oil cooler front header is cast iron and rigid bolted to the side of the block....FAR superior in strength opposed to the alloy neck on the PSD timing cover.
In simpler terms----There are no issues with prying the bundle into the front header on the IDI 1 hr job at most
