Oil Temperature

Anybody know the designed operating oil temps for the 6.0? I'm asking because pre-head-gasket fix, I was running sub 210 degrees (oil) on normal to moderate (90 mph) highway use while seeing 195-202 degrees for the engine cooling system. Now that the dealer has replaced my head-gaskets (and ARP studs), I am seeing mid 235's to 240's for the oil with the water being down somewhat in the low 190's.

I've been through the usual quantity checks (and even replacement) on both systems.

Dealer mechanic is trying to find out the specs for me, but I hope maybe some of you might offer actual Ford info, or at least operating experience. I thought maybe the cab-off/cab-on treatment (to get to the heads) may have cause a pinched line with the oil-cooler, but the mechanic assured me that such a case isn't possible because the oil cooling system does not have lines that travel along the frame/body.

Any comments or ideas would be greatly appreciated.

Thanks

Re: Oil Temperature

I asked this question once before and the response I got was oil temp on everage will be 10 to 15 degrees hotter than engine temp.

My normal oil temp is around 205 with no load and engine at 190 to 200 range.

The highest I've ever seen was 230 pulling a 10,000 TT up a long grade and my engine temp was at 215.

Sounds like you have a problem.

Re: Oil Temperature

Thanks for the info.

212 was the highest I had seen without any towing, and the oil was typically

Any ideas on what the head removal/replacement could have done to cause the new 30 to 50 degree difference?

The dealer changed the oil and filter. I've drained the oil and replaced with Rotella T, but I did not change the filter. I have pondered that the filter have some internal flaw restricting the flow of the oil, but I have never had nor heard of such an issue. I may change it out tomorrow.

Re: Oil Temperature

Is it possible the sensor or connection got damaged or is loose? I am also under the impression that oil is directed to the EOT sensor from the oil filter assembly. It may be possible that a bad, incorrect, or damaged oil filter may even affect readings. [img]/ubbthreads/images/graemlins/shrug.gif[/img]

Re: Oil Temperature

Per Ford,engine coolant 230 degrees before fan fully engages and 256 degrees engine oil temp for a back-up if the coolant temp. does`nt kick the fan on.
My eng. oil temp got to 246 pulling 13K, 7% grade 90 degrees outside temp and never above 230 on the coolant when the fan fully engaged.
The coolant will be higher up to about 190 degrees then the oil temp takes over and rises above the coolant.
Around town on freeway mines about 198-202 coolant and 206-212 oil @ 65 mph and 110 degrees outside temp.
