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

$32 is pretty cheap for the o-rings and gaskets both. I think I had that in just o-rings from IH.
Could be. Who knows anymore with the constant changing of oil formulations required by the government. Each one gets more and more 'environmentally friendly' and gets worse for engines.
