New oil cooler still high EOT?

I just replaced my oil cooler, flushed and switched over to elc coolant. Also did a coolant filter set up.

When I flushed, I did it with some Peak coolant system cleaner..
I did the first 3 or 4 flushes with hose water. I did these flushes before the cooler went in. I also did these flushes by just opening the drain and dropping the lower hose. The I did another 3 or 4 flushes using just distilled water. On the last flush, I opened the drivers side block drain plug also. I have the 5 gal water bottles from the first few drains on distilled. It looks clear?

When I did the oil cooler, the hpop screen had some junk on it. Now, it was new, in Dec, when I did the hpop.. And I switched over to Rotella T6 5/40 at that time. Before that, I had no way to monitor EOT/ECT. So I have no idea how long it was running hot. After the hpop, I noticed the temps were way off. ECT avg 190 EOT avg 225-240

So I did the oil cooler. Now I've got ect:195 eot:220

Did I not flush good enough?
Would elc mixing with ford gold do this?
Could the oil be the problem?
Oil filter? Seeing as how the hpop screen was dirty?
I used a napa coolant filter #4070 dosent say charged filter anywhere on it?
My degass does have a very tiny leak? But when I pop the cap, it has pressure?
T-stat?

What else could it be?

How are you measuring your oil temp?

I should add too, that if Im driving on city streets, the temps are pretty good. Maybe 190-195/200-205. It just seems to creep up durring extended runs on the highway, after maybe 10 miles.. I was driving into a head wind doing about 70-75 at about 40-50% throttle..

Gary,
Your oil temps still shouldn't be that high. I am not sure about the Gold mixing with the ELC very well. If you didn't flush it well, you may have something there. But you say you did it several times, so I would think you could rule that out.

What about the sending unit itself? Has anyone seen these go bad?

I'm still trying to find an answer for what other problem there are that can cause high oil temps...besides a bad oil cooler?

Every search I've done leads to a thread about oil coolers. Mine was bad. I was getting to 240 before within just a few miles on the highway. Now it only gets to about 220. So something tells me theres another problem also.

Anyone have any ideas or can share their knowledge as to what else can cause high temps?

Maybe it's plugged again. Have you read Karl's (nylyon) post on his oil cooler?

Have you tried testing/changing the EOT sensor?

Can a bad sensor give high readings? or would it just show nothing?

And yeah Shawn, I read it today...It's not what I wanted to read though...

I'm really hoping its something else? Just cant imagine I left that much stuff in there? But who knows???

A Ford Tech "tried" to tell me it was my sensor when I was on my 2nd oil cooler ... it was not, but it's worth a check nonetheless. It's probably a clogged cooler "again".

Did you do a flush "after" you changed the oil cooler?
