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 ?

Separate topic, but do you have a head temperature gauge?
Reason I am asking is that lean will get the heads run hotter. I assume your timing is set properly as it can impact both head and oil temp.

2056 requires the MPS to be tuned to work with the DJet. Your cam is an unknown from what you are saying. That is a concern as DJet will only tolerate very mild “performance upgrade”. Also, you will need a wide band O2 A/F ratio gauge to set it (MPS).

2056 can heat up the heads and the oil. Not saying you need an oil cooler, but many 2056 engines on the road have an external oil cooler.

Correct reading from your instruments
Correct tuning (timing, MPS, vacuum leaks, etc…)
Complete cooling system (that potential missing duct)
Doubt that shift rod guide will do a difference

Then you can see if you indeed have an oil temperature issue.
