Results back from Blackstone not so good

Hello Ford truck fans,

Just got the results of my oil sample back from Blackstone labs. The results show high iron and coolant in the oil. I have added the pdf file as an attachment so you can see what it looks like. Chuckster57 has been very helpful throughout my rebuild and hinted that theses engines have an oil cooler mounted on top of the engine. Possible that some failed o-rings area allowing coolant to find its way into the engine oil? The engine doesnt seem to use oil and I havent noticed that the coolant level dropped in the last 2500 miles. I have only had the truck for 2500 miles and when i drained the oil from the original purchase it was cold in the pan and had not started in a couple of months. I wonder if the new oil had some residual from the first poor drain. Has anyone had experience with these o-rings? Its a 94 IDI Turbo.

Thanks Vinnie

Sorry, you might have mis read or I may have mis typed. the oil cooler is mounted to the block on the Drivers side. IIRC the filter mount is on the back end of the cooler.
I did see the results. You might want to pressure test the cooling system and see if the coolant is "moving" under pressure. I'm sorry if I didn't make it clearer where the cooler is located.
There is a special set of tools for doing this procedure. You have to use a pressure gauge to know the starting point and then check it after a period of time. Radiator shops probably have this set, I don't yet :icon_wink:

FWIW Sears shows a universal set for $120.00 . I might have to get it

2nd edit: Autozone shows a cooling system pressure tester for "loan" with adaptors free
