My oil temp is located in the canton pan. Oil temps were climbing to 250* but when I`d shoot the oil lines coming from engine or the oil filter my infrared gun never read more than 190*

Decided to replace the sender type gauge with a thermocouple type gauge but the readings are the same.

After a ride at 4500 I saw 265* and climbing ....open hatch shoot every oil hose I can see, nothing over 200*
Line from oil cooler 101* ish
Pull the dipstick. feel the oil , doesn`t feel like 265*. Wouldnt that be burning hot?

Shoot the oil pan, 201*

next time pull the dipstick and shoot it with one of those lazer thermometer gizmos. They are cheap and a nice tool to have. Never mind...just reread it and you have one, dod you shoot the oil on the dipstick

I know they make temp sensor dipsticks for bug motors.... wonder if they can be adapted or if one is avail for bbc's??

most of the temp gun,s won,t give a proper reading if shooting a braded stainless an hose,i try to shoot a black hose or surface and have found that it gives a better read of actual temp.just offering food for thought.

yes, don't shoot the lines, try the filter itself

ICDEDPPL -

Is this a new issue or did you just hook up an oil temp gauge ?

If you have had an oil temp guage, Has your oil temp sender always been in the pan ?

Did Canton send you the 270* pan vs the 225* pan by mistake ? Bad joke, I know, lol.

Did you try shooting temps of all of the same things on the other engine? As someone else said the infrared won't work on reflective surfaces and I'd question the temps of a rubber hose if that's what you have but certainly the pan and the oil filter should be two good sources. Check one engine against the other and go from there.

Buddy of mine had the same issue. Changed the oil and temps changed. Don't know if he changed weights though. He wasn't sure of what weight to run either not knowing what the engine builder sets his bearing clearances to.

I`ve changed oil 3 times 20w50 and 50weight this time around. I`m shooting the AN fittings with the gun at the ThermoFilter (pictured)

SB , The oil temp issue
has always kinda been around in one form or another , I~ve always contributed it to some previous issues.

Mike, you remember the oil adapter was modified (drilled) I think for more flow ? Maybe it`s not large enough and I`m not getting enough oil flow heating up the oil in the pan.?
At 4200rpm I have 70psi at the mechanical on the Thermofilter (pictured) but 50psi above the oil adapter. (also switched those gauges to mechanical)

I plan on moving the oil pressure tap to the oil galley as Ive read above the oil filter may give wrong readings but maybe that has something to do with it..

Can you suck some oil up the dipstick and check it with a cooking thermometer, that would end guessing.

How about a bourdon tube temp gauge mounted on the engine , to rule out any electrical issues
