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 ?

It’s not broke in yet
It will come down if only a little bit
(Maybe 10 degrees)

These cars run hot
I’d run synthetic after it is full broken in as it doesn’t break down as quick at temperatures

So many people add an aux cooler for a reason

I have had many teeners and put coolers onto all of them except 1
Sold that car instead

When you have added remote cooling, where was your favorite spot for the exchanger?

well I like the front, due to the effeciency of frontal air

my 4 and my 6 both have front coolers

I did own a 1.7 for a while that was abit tired and always ran hot
I put a rear cooler into that car because it was less work and less expense
that rear cooler with oil filter pick up used to be under 200 (sure it has gone up some in the current world)...

it took the edge off.
kept the temps in check
did not completely eliminate all of the heat... but enough to make the car useable.

ended up selling that car also
