What are your peak oil temps on the freeway?

Just curious. I am mainly interested in stock configurations with no external coolers.

Should have installed the guage before I installed the oil cooler - but I didn't. With the cooler I've never seen any temps over 200f.

I'm in the 240-260 category myself. Scares the crap out of me.
Yeah I'll do something about it, but now that winter is here it's much less of an issue.

Mine has always run a bit cool. This makes since, because the thermo-flap is kluged wide open. I don't usually drive it in the coldest months, I reserve the coldest days for after midnight frozen finger tool abuse.

This is something I have been chasing down. I have a completely stock 1.8 with L-Jet. Up till a few weeks ago it ran a little hotter, but a fixed leaking Retard Vacuum canister brought the timing into spec. Now my freeway heat is dpendant on a few factors;
1) Heat of the day, 2)Length of freeway run, and 3)How hard I ran.

Freeway driving at normal speed of 65-75 for 30 minutes. Flat, one or two small hills.

on a 90 degree day I get to 220 on the freeway, but once off the freeway and in town right away it goes up to 230.

On a 70 degree day I get to 210 on the freeway and up to 220 running in town after the freeway

On a 60 degree day I will see 195 on the freeway and 210 comming into town.

If I never go onto the freeway and just drive around town for 30 minuts my temps seem to get to about 210 or 220 on a 75-95 degree day.

From a lot of othersI would say I am running hot. But my mechanic says its just fine. I live in the dry desert at 4,000 feet with an average temp of 80+ degrees. In the summer we can see 100+ for a week or so.

AND: I use a brand new Electric VDO gage and sender in the Taco plate. A battery operated Voltage Temp gage Thermocouple down the dipstick, and an infared temp gun to calculate the temps. I calibrated/checked them all with a pot of boilg water and a cooking thermomiter.

oil temps

I just installed a VDO-310012 oil temp gauge 120-300 degree range ,and temp senser is a yr old.
I just compleated a 600 +mile trip to the Indy fall color run, to and from with a very spirited 50 mile run in the middle of it .
Outside,temps in the low to high 60 degree range , never went over 190, speeds in the 80 to 90 range, on the drive to and from. needless to say i was very pleased.
My stock gauge was always very close to the red line. This was a good investment for just the peace of mind.
My 914 is a 1.7 very good condition,i.e.compresssion, single 2-blr. carb,oil is Mobil -1 , 15-50 .
Hope this is a help .
Dave

Running 70mph with 70deg outside air temp, I was seeing 220 in the sump.

2270cc with stock cooler. Limping it back to school before I got the external cooler in.

Later,
Tom

Wow, I'm running way too hot compared to all you guys. On a 90 degree day after an hour on the freeway at 75-80, I'm up around 220-230, then after 2 hours I'm starting to see 240, and I have seen higher. One time I pulled off the freeway on I-5 and saw a brief 260. I shut it down for a bit after that. The engine still runs too, I am amazed.

And this is a stock 1.7 too. Hopefully to be replaced by a 2.0 in the near future, if I can find one.

Why is it running so hot? Is your oil cooler pluged?

Temps

jkeyzer:
Is your engine tin intact , the two pieces on the very bottom. Also the two flaps?, air deflectors on the bottom rear on the floor pan. these disrupt the air flow to create negative air presssure to help suck the air out and through the engine and cooler. Are you running lean? I think this adds to the problem.
My 2 cents. Dave

I agreee wit chris check the cooler to see if its pluged.

I'll check the engine tin next time I am under the car. I flushed the cooler with brake cleaner last time I had the top tin off (which is all there I think...) but maybe that was not enough. I installed a thermostat and the engine tin cooling flaps a few months ago. Unfortunately I didn't have a gauge then so I don't know how bad it was before the cooling flaps were added....

I definitely don't have the ones that go under the firewall.

The little flaps (air deflectors) are very important to good cooling.... If you don't have 'em, see if PP offers these. If not, you should fabricate some out of some mud flaps or similar material.

How much temp drop should I expect?

I am looking for around 20-30 degrees to come from somewhere.

Jeff, if you can get back to San Diego I'll give you a set of the flaps!

Not to be a redundent ass, but does youtemp gauge and sender work properly, or are they the right ones for each other? Those flaps are really important. Try High Perf. House in Redwood City. Might have them.

I have checked the actual oil temp by sticking a thermocouple down the dipstick tube. The measured temp was within a few degrees of the temp shown on my VDO gauge. I have noticed the VDO gauge changes a little with the engine on/off, headlights on etc, but even if the temp was 240 instead of 250, I still want to fix it and get down closer to 220.
