For the oil temperature where did you place the gauge sensor? Is it sensing the oil coming out of the engine or after it returns from the cooler. If in the center of the oil filter housing it is sensing after it is cooled. In that case it should follow the coolant temperature until the oil cooling system can’t keep up. Usually just slowing down and reducing load will allow it cool back down. Ideally 100-120C is a good place to be before the cooler.

For EGT I don’t know where these engines usually run. It will be extremely load over time dependent. Around 1,200 to 1,300 f is when things glow.

For these engines and especially for the turbo you need to learn the fine art of gentle warm up and letting it idle after being loaded to let things col down while the coolant and oil is still flowing. Shutting off the coolant and oil flow while things are near glowing will help to crack heads and destroy the turbo.

Subject: temperature questions

Volks,
I have a syncro with a AHU [I think] TDI conversion. I have some new gauges, oil temp gauge and a post turbo E.G.T gauge. I'm going up to Lake Tahoe, up I 80 this Saturday.
What should the oil temp normally run, and what's the maximum where i should pull over and let it cool?
Same question on the EGT, what's the maximum it should get to before i downshift or pull over?
Thanks,
Mike
