Overheating

[FortneyF350]

I just replaced head gaskets, injector sleeves, rebuilt oil cooler, replaced waterpump and replaced a head. My problem is the truck is overheating and I'm not sure if I have air trapped in it or more problems somewhere I ain't looked yet

Update on overheating problem, now the oil and coolant are mixing, I have coolant in my oil and oil in my coolant?

 

[DaveBen]

Oil cooler is leaking water to oil and the other way around.

Ill pull it off and check it again, thank you, ill let you know

OK, I pulled oil cooler and put another one on that I had in the shop, I still had my oil plug off,from draining oil, and started filling with coolant, coolant was dripping out of the oil pan, I'm at a loss. ....

 

[DaveBen]

Both oil and coolant are mixing... That is very strange, as oil is under a lot more pressure than coolant. You said that you filled with coolant and you were getting coolant out of the pan? May need to remove the heads and check for a cracked head or cylinder. I am out of ideas at this point.

OK, thank you for your time

I would go back and recheck all your work. If you are having coolant leak from the oil drain plug just from pouring coolant into the engine, then you have something out of place, since there is no real pressure at this point.

Another suggestion, you may want to post this over on www.oilburners.net, which is out sister site. We have many member over there that have the OBD PSD trucks, and you may be able to get a faster answer over there. Just make sure to post in the 7.3 Powerstroke section, as the site also has a section for the 7.3 IDI, which is not the same engine.
