Yes, another oil temp thread...

That is a bit on the hot side. Anything over 250* isn't generally good... Does the limp mode self-clear or require an ECU reset?

Thanks for the rep .

Limp mode self-clears when the temps drop. It may require an engine on/off cycle but there is no need for a code reader.

I'm putting in the cooler because I swear the engine loses power when the temps go over 230F.

Is their a relationship between needing a new short block and my high oil temps often 240+with low ambient temp. 258* was max when I put it into my own induced limp mode and dropped the revs down to 2500.
I am hoping I will not need oil an cooler after new short block. Keep hope alive.

first the too are not related, and If you are going to be doing some spirited driving?
It's highly recommended.

Meaning you just had a new short block installed and the oil temps are high?

That makes me wonder if you have a poor cooling... like maybe they resused the old head gasket when the engine was assembled.

Does the oil look milky? Any evidence of low coolant?

Sorry. I have just been prescribed a short block arriving next week. The coolant has remained at proper level. The oil looks milk free.

I just got back from 1600km long distance travel and during the whole time I was monitoring my oil temp... It always stayed below 210F even with more than occasional spirited driving

Break-in was done properly and synthetic oil thereafter. (mobile 1)

I hate you.... Mine is almost always above 230

Reading all the oil cooler threads now...

It's not a break-in or oil type issue. More important to report would be your ambient temps, cruising speed and RPM, altitude, and A/C on or off.

Before my oil cooler, I could easily highway drive in the Midwest with temps at 210F even on an 80F day. But then immediately stop in traffic and that illusion quickly disappeared as airflow into the engine compartment became stagnant.

Your next 80+F day, go drive around for a while to get the oil up to temp. Then do some hard pulls up to 5-6k and then stop dead in traffic. Do some stop and go for 10 minutes with a few revs to 4k in between (stop light to stop light). To exaggerate things, keep your AC off too (the compressor turns on an auxiliary fan that drops oil temps about 10-15F). See where those oil temps end up.

So oil temps are high but you don't have the new block installed.

Sounds to me like they figure something is amiss with the pistons and rings, so yeah, trashed shortblocks are potentially related to higher oil temps.

I'm not exactly sure why tho'... WarmAndSCSI, or someone else with lots of engine building experieicne, may be able to elucidate...
