Temps After Head Gasket Replacement

Recently had the head gaskets and oil cooler changed along with installing ARP studs. The heads were also decked. There was signs of seepage from the gaskets. A year prior to this I changed the oil cooler and did the EGR delete and also added a Sinister coolant filter along with a flush with restore and Cat coolant installed.

With exception the second filter, all have been clean. The second on was full of gunk.

I have an SCT tuner set on the performance tune.

This morning the temps are the worse they have been since having the work done to it.

The first pic is just after getting to temp.
The second pic is 30 min later after running 20 miles on the highway at 65 mph. The ambient temp was 20 degrees. The coolant temp never went above 189 and the oil temp kept gradually going up until it leveled out where it's at.

Could this be a faulty temp sensor or thermostat? I find it hard to believe that I have clogged another cooler especially with me having fkushed the system and with the system being emptied again for the head gasket repair.

Check your EOT and ECT after it sits all night before you start it to see how close the readings are. There normally should be only a few degrees difference when its cold. If their within a few degrees when its cold, I would start looking towards a clogged oil cooler. Its unfortunate, but it happens.

The only way to check deltas is to have engine at full operating temp, doing 65 mph on flat ground cruising.. ECT AND EOT should be less than 15 degree split..

Is that what it was, prior to starting? You are supposed to check the accuracy BEFORE you start it.

Donnie, get in your truck after work and just turn the key to on, read temps.

Guys, I have a hard time believing that 3 oil coolers plugged up, with two having a coolant filter.

It happens, most especially if the coolant system isin't maintained, flushed correctly, thoroughly, and using chemicals. He needs to verify the temp sensors, and perform the delta test correctly, though.

Oh, ok, I skipped the chemical flush when I switched over to elc, i've been running the coolant filter on mine for about 1500mi, about to tear into it to replace the oil cooler.

In the summer after new thermostat my deltas were 7-9 then before winter when still warm I switched oil to t5 10-30. Deltas went up to 9-11 but stay closer when pulling with this oil than the 15-40. No in dead of cold my average is 184 thru 188 on coolant and 194 thru 198 on oil. So with that said what oil are you using. Also this cold is hard to keep them warm coolant wise but the oil will always stay warmer.
