I haven't checked into this thread in a while, but have you already verified your temp gauge readings are accurate? Do you have an oil pressure gauge to corroborate the temp readings? If you're getting big spikes in oil temps, but your oil pressure is staying steady, then that might imply it's just your temperature sensor being affected and not the oil.

No pressure gauge, but the oil temp gauge was checked using a high-end IR thermometer. Readings from the thermometer at the sensor spot were within 5-8 degrees of what the gauge was reading.

Well... another update.

Wrapped the headers -- no change in temps. Actually, temps are higher now than ever, but it's been getting warmer out so that makes sense. Today driving across town... zero boost, casual driving, all under 4k rpm in 78 degree weather got me 230 degree oil temps.

So seems that I can rule out the headers heating things up. I'm thinking that no matter what, if the radiant heat from them was heating up the oil then the wrap would have SOME effect.

But now this leads, again, to a very odd situation where the oil is getting hot but there doesn't seem to be any cause that I or anyone else can think of.

I'm going to check the gauge sender again... it was checked via IR thermometer but I'm thinking to test with boiling water as well.

Other than that... the only things that changed around the same time were adding an AOS, changing to Grimmspeed intake from SPT, and getting a retune.

Any thoughts or ideas are super welcomed :/

Like I said before, it’s either the sensor or the tune. I think like you said, you have no choice to troubleshoot your sensor first.

I hope you are right.

How do you think the tune could affect the temp though? AFR's look pretty normal...

The AFR itself is a ratio independant of heat. It follows the tune, so if all incoming data after the meters stay the same or don’t vary more than 25% from the tune, then the AFR will always be perfect.

It really depends on many things. The basic generalization is that a more agressive tune makes the engine perform harder which creates more heat. The tuner can control EGTs, cooling, timing, etc in different drive cycles. If the tune isn’t as efficient performance wise for the engine, as it could or used to be, then the extra energy has to go somewhere and most often that’s seen with a temperature change.

I don't see this as tune related. A hard part was installed that should really make things cooler, aside from radiant heat. Also, the tune will only correct to *50% in closed loop, but you also don't want it to be there.

Have you tried a new sender and new wires?

Is your oil cooler working properly?
