2001 7.3 Oil in Coolant, Coolant in Oil
I rebuilt my engine last year and have put roughly 10k miles on it at this point. Over the winter the icp O-ring blew and was leaking in a similar fashion to the HP System End Plugs. So in the giant puddle of oil on the ground I noticed little red drops of coolant. Ever since the rebuild I had not noticed any oil in the degas bottle, but now with a closer look there is some residue.
Over the course of time I had been driving the truck I noticed really no coolant loss or raise in oil level during service intervals
So.. What could this mean from my research I found a few things.
Oil Cooler O-rings- Replaced during rebuild (Ford)
Oil Cooler- Was cleaned but not replaced
Injector Cups- All 8 replaced by machine shop and flow tested (Dorman)
Head Gasket- Heads were cut, and put back in with studs not bolts(Victor-Reinz HG)
Front engine cover- Checked for plumb, was straight no cavitation noticed on housing(Victor Reinz Gaskets)
Injector O-ring- Stock cores rebuild to 238 cc, installed with new o-rings
Given what others have said the cooler is the first place to look, I just took out a faulty injector so While things were removed I took the cooler off to inspect it again. I was just going to replace it but for 240 dollars I am just going to assume it may be a waste of time and money, given my luck I am probably just going to have to look at the heads or the cups....
Any info or help would be appreciated kinda at a wall here with what to do, given each system is contaminated.
