Ron's 914, High oil temp Options

[Ron914]

Hello all,
It's been about 4 months since I passed my smog test and thought I would be on the way to finally be able to drive my 4 year project .

Well I have been enjoying driving it but only for short trips around town because I feel it has a high oil temperature problem . This is after a short drive around town of 30 minutes . A 45 minute drive will bring the needle on the gauge right to the red zone ,which looking at Phil's calibration photo would indicate about 250F , I don't continue to drive once I get to 250F and pull over and let its cool .



Not exactly sure why or if it really is high ( I don't want to damage my new motor ) but I was given a few things to check by the members hers @Superhawk996 , @emerygt350 .

First I checked my oil Temperature sensor to verify type and operation.

It is a VDO 200 C sensor .


I have the later oil gauge . I removed the sensor and placed it in 212F boiling water and it seems within the correct range on the console gauge .

I am using a Efeng turkey fryer thermometer to check against the gauge in console . The thermometer is accurate . The gauge ( apex seems close to the same reading



There was a discussion the other day on this subject with the question of whether missing a cooling tin on bottom of engine could cause the overheating problem @930cabman .

I have the same issue as I have the tin that the shift rod passes through removed because it the shit rod comes into contact with the tin installed and it shifts better with it removed .

Wondering if I should work on getting it reinstalled to help my cooling ?


I have also worked on the cooling flaps /thermostat but will start a new post for those questions .

I saw a comment about the type of oil . It sounds like Synthetic oil might be a better choice for air cooled oil .

I currently have no oil in my motor and was wondering if Mobil Syn oil would be better than putting back in the Valvoline VR1 20-50W ?

I have one of these, but have never used it so, if you get one YMMV.

I’m with the others, you're running too lean/too much advance…. As for oil, ugh, plenty of opinions on that, bottom line, synthetic has good properties for heat, but it’ll find places to leak. Dino is best, many have ‘enough’ zinc even thigh they don't advertise it, but you can look it up, anything labeled high zinc will be more than the recommended needs.

I believe Ron's car has a catalytic converter and my understanding is you should avoid high zinc oil if you have a catalytic converter as it can cause premature failure of the converter if the engine is burning oil. Good luck finding another one if his fails, and if it fails he won't be able to pass future smog tests.

Hi Broheen ,
Thanks for the input on the oil , I have been using 20-50W since I got the car so I will just stick with it , only difference is I was using Castrol and now using Vavoline .
If you remember (I know this has been ongoing now for a couple of years) my smog issue was getting a pass without a catalytic converter ( which I did) . That was a challenge because I wanted to do it legally .
