Post Oil Temp Sender Location

There was a thread a while back discussing options for installing an oil temperature sender, but I can't seem to find it in the digest.

It involved tapping the turbo return line banjo bolt, but there was some concern regarding this being an "accurate" temp given the oil is coming from the turbo.

On the other hand, one person said that this technique essentially gives the temp of the oil in the pan.

What's the scoop here?

The other option is to tap the oil drain plug. I saw that post as well.. but my search did not bring it up.

I just got an extra oil drain plug and am waiting on getting a oil temp gauge so I can take it to some machine shops, I found a good one, but I dont know yet if they are going to modify the stock bolt or make a new one. Ill let everyone know when I get it rolling.

Is the magnet in the stock one just a nice thing to have or did Porsche see this necessary? ie, am I risking anything losing it for a sender?

I liked the option of tapping the plug in the oil filter console, associated with the oil cooler return (?) line. - if I understood correctly.

Is the sender mechanical or electric?

If you use an electric sender, then you can tap the drain plug.

If you use a mechanical sender, then you have to make a custom drain plug (which I had cnc'ed).

I highly recommend mechanical gauges over electric gauges since they are more accurate, and have a finer resolution (the electric gauges have a 90 degree needle sweep vs. the mechanical gauges with their 270 degree sweep).

Here are my cnc'ed oil drain plug pics for the Autometer mechanical gauge sender:

Hi everybody

I placed my aftermarked oiltemp sender right in the oil change screw (I guess sump area is the coldest one). Electronic sender unit and oil temp gauge comes together from american company Equus. The problem is to update the screw with the rigth gas windings to fit the sending unit.
Hope this will give you an idea.
greetings Frank
