EOT and ECT Temp Difference is Increasing

When I first got my Dashdaq/Spartan my temps were running ECT-200 and EOT-202ish. The difference has been building for some time now and now my temps are about 20-30 degrees different, with the Coolant temp being low and Oil temp being high. about 194 versus 215-220. What is causing this? I'm sure its "fine" but I want to fix it.

Sensor? Need a flush?

55K on truck, tuned for about 20K of that.

Well, that's what I was leaning toward, but wanted to throw it out there. So if its clogged, what's the best way to find out?

If clogged, can it be flushed out or do I need a new cooler? maybe blow it out with an air hose?

Monitoring your ECT vs EOT is the correct way to find out if its clogged. By the numbers you are seeing it is clogged. I would recommend a good flush and some cat elc. I would also recommend a coolant filter. That will help keep it from getting clogged in the future. I dont think flushing will unclog it but its worth a try. You could also back flush the oil cooler and see if that helps.

Is it the difference in temps or the actual individual temps that is indicating the clog?

There should never be that much difference in oil and coolant temps.

Oil cooler is probably the issue. It will more than likely need to be replaced, rather than just flushed.

Roughly, what does an oil cooler cost? Not installed.... Thinking I could do it myself.
