Stop talking sense.
Next thing you'll be looking for fuel trims...
It's an old sprinter if I remember rightly so the second poster probably nailed the ops issue on leaky injectors especially if worse when cold.
FWIW, I had a live feed pre-turbo EGT in an old TD truck of mine. The engine was the veritable VW AAZ Td. it had some* pump tuning and extra boost and the EGT was what I 'tuned' it by. Basically, Anything above 700 degrees was in danger of starting to melt the pistons.
a steady 50mph on the flat saw EGTs around 200, and could easily hit 650 in 2-3 seconds if you booted it. It would then drop to 300 in just 2-3 seconds once off throttle. temps really do rise and fall that quick.
Proper gauges (real time) are often called 'worry gauges' for a reason!

Yep. An oil pressure gauge also adds a whole new level of worry.
I'm sure an actual mechanic who works on modern cars will put me right but the oil takes longer to reach temperature than the coolant. Roughly twice the time in the cars I've had oil temperature gauges in. I think it was a bit quicker in my current car as it's turbocharged, but the gauge is disconnected due to leakage.
So think about that before the Italian tuneup.
Depends if you have a sandwich plate as factory fit.....
But yeah, if you're gonna thrash it let it warm up first

I've noticed little difference between a 'sandwich plate' and external oil cooler, on the same engine.
Oil temp always lags, wether that's an issue with modern oils/engines or not I don't know. I'd imagine not
