EOT High. Traveling Help

[smuesse]

I have just finished a trip from Waco to Harlingen. When I started out my deltas were fine. I stopped after about three hours for lunch and when we left there I noticed my eot was about 10 deg higher very quickly. I kept my eye on it and noticed it would jump around in temp quite a bit, but would hover around 15deg delta,and less. We stopped at a sign and took back off the delta jumped up into the 20's. For the rest of the trip the eot would bounce around 23 to 27 delta with the cruise set. I checked the coolant and oil at a fuel stop and saw no signs of puking or low levels. Leaving the station after 15 minutes the eot showed back down to 198. After 5 mins it was back up high again.
Now I'm conserved cause we are 450 miles from home. Could it be a eot sensor? I not is it safe to drive back to Waco on Friday? Any advice is appreciated.

As long as eot doesnt exceed 235 you'll be fine limping it home. Eot sensor could be bad. It's strange that deltas would increase that quick.

Let the truck sit overnight. In the morning when it's cold look at ECT, EOT, and intake air temp (IAT). They should read within a degree of each other. If EOT is way off then the sensor is bad.

EOT will not just jump up within a minute or two. If it's jumping +/- 10 degrees within a minute or so then something is goofy with a sensor, especially if your deltas looked good up till now. Normally with an oil cooler restriction it will slowly build up, not do it all at once.

I guess you still have the EGR cooler in place

He's still got a egr cooler I think. +1 on Letting it sit over night. And you will get a cel if eot passes 235

I'll check that in the morning, thanks for that. Seems like i remember the eot being higher in the mornings when i fire up. Yes I do still have the cooler on place. I tried to install the straight up pipe and cooler plug but I could not get to the bolts on top with the turbo in place and limited on time. I have the egr cooler delete kit that I plan to install when I have a reason to pop off the intake.

No reason to remove the intake when you do a egr delete.

Iv read something about that but thought it looked like all the bolts would be out, just not actually removing the intake.

I've never done one without removing the intake. I always take them off and clean them. In the sinister instructions it said you don't have to remove the intake. You might just have to break it loose so you can wiggle it around

I think I'll remove it so it can be cleaned. Specially if I have a oil cooker problem.
