Engine Temp question - not what you think....

Post by Gen3AntiqueAuto » Tue Nov 21, 2023 4:03 pm

Has anyone figured out what the temperature of the oil/crankshaft/mains/rods is inside a Model T when running well (and also when boiling over)?

That would depend on a number of variables.

Around 200 F would be a good guess, and hotter under hard use and/or hot weather.

I have never measured the temperature of the crankcase. But after reading another topic, I am going to measure the temperature of the crankcase and of thr rear axle pumpkin. I know the pumpkin gets hot going up a long hill, but not sure about the crankcase temperature. The car has been put away for the winter..... I think.

Probably the best way to obtain temperatures of various parts of the engine would be with an infrared temperature Gun. Simply point the laser pointer at the part of the engine you want to test and remotely obtain the temperature. You can get one from Amazon. Jim Patrick

Here's the behind the scenes reason for the question. I could not find the "pinch nut" small block chevy rod nuts I normally use (what a messed up broken world this is) and after seeing what happened to the inside of this 25 engine I do not want to use cotter pins in it.

I did find some nylocs (after days of searching). We run nylon timing gears and they don't melt so the oil itself is not too hot - my concern was the "long stick on the other end of the explosions" getting too hot and softening the nylon locking part of the nut. I dont think it will but I was looking for info to prove the theory. Now I have the metal ones I wanted in the first place so I think it's all good.

Loctite works and I think it’s only good to around 400 degrees. You can get self locking stover nuts from Amazon in a couple days. My machine shop has the Chevy nuts by the gross.

My machine shop had them by the box too - before they went out of business. :(
