High Oil temperature, Concerned the temperature is getting to high too fast . Options

[Ron914]

In preparation and hope that I pass my smog test I want to go on the So. Cal.Toy Drive in my 914 on Saturday (not sure if this is a good idea) .

I need to address what I think might be a high oil temp problem .

After driving around town for 30 minutes the photo shows my oil temperature oil gauge and a actual thermometer reading using a turkey fryer thermometer.

The needle on my console gauge gets very close to the red high mark and sometimes just about to cross into the red .

At this point the turkey thermometer reads ~216 F degrees .

My Dakota Digital head cylinder temperature reads 111C (231F) .

It is almost 80F here today in sunny So Cal. but this seems too high for me . What would be a normal reading for the oil temp gauge?

This is a newly rebuilt motor (less than 300 miles on it).
I did not replace the oil cooler (its original) but it was flushed and was clear.

The baffles are held open by spring tension since the thermostat is not working but I checked they were open by removing the coil and checking through the bolt hole. This should be ok until I get a chance to replace it .

If I pass my smog check tomorrow or Thursday I am hesitant to take the car on a long canyon drive , so not sure if I can attend the toy drive this Saturday.

Any thoughts ?
