Using the oil pressure relief for???

[Plumb1]

Can the oil pressure relief on the drivers side of the block be used to install the temp probe for a Bosch oil/water temperature gauge?

Thanks..

Hey!

What is your case number?

Why not use the original oil pressure location? You can install a T fitting there for additional accessories.

Because there is already a tee there for the original sending unit and a bosch oil pressure gauge.

With the after market ignition and engine tin, the amount of room doesn't allow for that many brass fittings.

Will have to check on the case number.

Good advice David.


I had actually thought of utilizing that drain plug, only for the fact I would be afraid of running something over and the thermometer getting broken off.

But that be where she ends up

This is not the best pic, but it was all I could find to illustrate possible spots for an oil temp sensor:

If you have a "universal case" you may have the T3 oil dip stick hole located at the red arrow. For Beetles, there will be a block off plate here. Drill and tap a hole and mount your temp sensor. This will represent the oil temp of the oil in the crank case. One thing to consider... the oil level in the crank case of a running acvw engine is almost zero. Ther is already so little oil in the engine, most of it is in motion while the engine is running at anything above idle. You want to mount your sensor as low as possible.
Even if you don't have a pre-drilled hole here you can drill and tap directly into the case if needed. Just make sure there isn't any interference with the engine tin.

An alternate (and possibly better) spot would be the round oil galley plug just to the left of the block off plate area. This is part of the oil galley and is the INLET to the oil pump. This guarantees you will have a flow of oil past the sensor. Again make sure you don't have clearance issues w/ engine tin in this location.

Personally, I don't like the idea of the oil drain plate sensor only because it is at the lowest point of the engine and reduces the ground clearance. But considering adding a deep sump would probably end up with even less ground clearance it is probably okay. It is other wise a very good spot because all the returning oil pools at the sump plate so you get the temp of the oil just as it has returned from around the engine.

Wow Ashman.

That is an awesome reply. Thanks for putting in the effort and energy to do that.


Pretty sure I can figure something out from that for sure.


Again, thanks.

Maybe the sender needs a prophylactic to keep it safe.

Have been super busy with work all week. This morning was the first opportunity I have had to even go in the shop.

The number stamped on the block is: AK170736
VW identified as 1973, US model.

Another website offers that the case is aftermarket. Not sure how that is possible. It is a 44 year old car, so anything is possible.
