Temperarute gauge!

Looking good. (I probably would have trouble trying to drive and convert temps at the same time:)--Let's see 78°c=about 172°f :confused:)

Hi 51 Merc!

For me is much easier to read in ºC than in ºF now let see what happens with temperature on each head.

Thanks for your helps

I do know that when trying to use my voltmeter near the engine, the readings are erratic due to interference from the ignition.
It's best not to use resistive wires or caps, it puts too much load on the HT side of the ignition. Purely my experience, your results may vary.

Have you driven with them long enough to warm up the engine and see what they show? I'd be interested to know what you see.

Funny, you made the same observation that I made when I first looked at the gages. Until I realized that the engine is up to operating temp.
They read appox. 78° Celsius which is appox. 173° Fahrenheit.
 
Hi Harry, You have done good using two mechanical gauges, that's the best way to go for sure. Stay away from electronic crap on vintage cars. Regards, Kevin.

Koates!

Yes, many people told me to install this mechanical gauge. With electronic gauge I pretended to read exactly the temperature but It could not be possible.

Hi Old Henry!

Here I attach some pics how temp gauge works running for a while. It shows 72º-161Fº. Perhaps a bit low.

Other question oil mar les 30 after a while running, Is this normal?

Your temperature is fine. Better a little low than high.
Oil pressure less than 30 after warmed up is normal. The engine is lubricated by oil flow, which you have at any pressure, not oil pressure. It also depends on the oil you use. In the summer when it's always over 60° F engine starting temperature I use S.A.E. 40. It gives a little higher oil pressure. Between 32° F and 60°F starting temperatures S.A.E. 30. We get colder than that in the winter here so I'm trying 20W-50 this winter. Still seems like the pressure is low. But, as I say. I don't think pressure is critical.
 
I'll add to the great info given. Temp is good at removing any moisture in the oil. If your car never reaches a good hot temp, water will remain in the engine. Typically a good running temp is over 180, till it goes to 210, Thats why they say you need to drive them not just idle them in the garage. Flatheads dont need a lot of oil pressue at hot idle, if you hit 20s hot idle you are doing very well on a stock motor.

I good infrared temp sensor is a nice addition to the toolbox too. Many uses, from testing (my interpatation of a quote from bruce lancaster) your ham sandwich , dog, to detecting blocked raditors.

Dear Friends!

today my engine has been running during 40 min. So I took pics when I arrived home, I tested with infrared temp sensor too that is according with mechanical gauge.
I installed SAE 15w-50 we are in summer now.

tomorrow i will run my engine for more time in order to have more info.

I will be back with news.

Thanks
