I don't have the temp guage up and running yet.
I can tell you that the oil tank and filter are hot to the touch. I can hold my hand on it but starts to hurt. That hot.

I remember years ago not being able to pull the dipstick on a typeI motor. That was hot.

What temp is considered too hot?
Safe range is?

KT

180-220 OK
230-240 warm
240-275 hot
275-300 real hot
300+ too damn hot

220-230 tops if you want it to live.

I just picked up an oil temp gauge. Hopefully it will respond with the proper temps from the sender I have.

There are 3 spade connectors on the back of it (a +, a - and an S). Am I correct in my thinking that the "S" is where the sending unit wire is connected?

Wish me luck!

vdo cockpit or a temp in the combo gauge? taco plate sender?

Aaron
it's a VDO cockpit guage. Sender is in the Taco or that thingy that looks like a tuna can held in by a bolt under the engine NE of the oil drain!

the sender that is in there is calibrated for the console and the in dash temp gauge.... i believe the cokcpit one is different

Hi,

I have the same questions, did we verify that the sender in the taco plate is wrong for the Cockpit gauge?

Last time I drove the car in warmer weather the gauge was 3/4 of the way to the hot side.

Can I just put a cockpit series gauge in there (change sender yes or no?) and find out how hot, hot is?

I don't really trust the 30 year old gauge! But I'd prefer not to cook a new motor either...

~200 is optimal, over 230 is too hot ...

do a search.

wasn't long ago, but someone posted a table of compatible senders and guages.

I called VDO USA. They actually make several temp probes in the 150deg C range.

To be sure, I am going to remove my sensor and place it in boiling water with a known good manual thermometer and then calibrate the electric gauge.

Boiling point for H2O at sea level is 212 deg F.

Checked several hot spots with the pyrometer yesterday after hotting it up.

oil filter 194
oil tank 160
oil inlet to cooler next to header 204

It's currently wired to stock temp guage in console, reads at "P" in temp swipe. Same as hot FOUR.

Someday I'll finish the wiring.

KT

sounds like you could use one of these.....

JK....shameless plug..AA style

Already got one of these...

what about a gas gauge?

Ordered one of these for the console in place of the temp guage...

Bruce Anderson says, of the 911 motor--
230F is hot.
240F is very hot.
250F is TOO DAMN HOT.

Synthetic oils can withstand high temps better than old-fashioned "dinosaur" oils can. But heat has other bad effects on the engine, so keeping it under 250F is pretty mandatory IMHO.

...You are talking six-cylinder, right Trekkor?

Oh, yessss

And here is what Jake says...

180-225 is perfect..

225-245 is very warm and will require oil changes more frequently as it heats up the oil and breaks it down faster

250+ is very hot- Shut her down unless you have a pressure gauge and can ensure that you still have atleast 40 pounds of operating pressure.

Hot oil is thin oil... thinning out the oil is what spins bearings and wears parts.

Oil temps are directly related to RPM and ambient air temps.
