engine and drivetrain Three OIL sender (original + temp + press)

[Xhrismar]

I want to install the factory sender and also a temp and press oil sender (both 1/8-27 NPT).... I would like something similar to the adapter PARKERPERFORMANCE used to have, any comments?

[andreb]

I run a VDO sender that transmits oil pressure to a gauge AND runs the OE dash warning lamp. I pull the oil temp with a drain plug sensor which is really where you want it.

But which adapter did you use? i have the senders

[visionaut]

I use the back of the head for oil pressure gauge and the OEM oil light. And the oil drain bolt location for the oil temp sender.

VDO makes an adapter for their dual oil pressure sender (gauge and warning light) that is similar to the Parker Performance one that you picture, but with only one threaded opening.  

 

Truth be told, that location atop the head isn't the best location for an oil temp sender.  By the time oil gets up there, it's cooled off considerably from its starting point in the sump or oil pump.  If you don't have a tii and your car is a 71 or newer, examine the oil filter housing carefully and you'll notice a dimple cast or machined into the housing.  On a tii, this is drilled and tapped for the oil line that lubricates the injection pump.  On carbureted cars, it's just a dimple.  You can remove the filter housing, then drill and tap the dimple for your oil temp sender.  It then measures the oil temperature as it's coming out of the oil pump/filter.  And it's a lot less vulnerable to damage than a sender in the drain plug.

Yeah, I use that VDO adapter for pressure. And I know the temp sensor runs slightly cooler.  No biggie.  So I guess i'm doing it wrong -- but haven't had any issue with the drain-plug oil temp sensor location in over 18 years (but then again I'm not off-roading).

Sender in the drain plug reads somewhat cool, but works.  It's messy to change the oil.

 

Sender welded into a boss in the pan reads somewhat cool too, but works.  The extended bulb sender DID make a difference.

 

Sender in the filter adaptor reads higher, but susceptable to heat soak from the block.  Also works.

 

Sender in the external oil lines to the remote filter also works- tends to read pretty accurately at full chat,

as AN hose is, apparently, a pretty good insulator.

 

Sender at the back of the head is useless, as there's no flow back there.

Unless you're oiling your turbo from it, and even then, it's not typical,

since it may have heat from the head and valve train added.  Or cooling, depending...

 

Sender in the diff is good- there's a flat spot to face, drill and tap that works pretty well

 

Sender in the trans is pointless- the trans simply doesn't overheat.  It tends to follow coolant,

just as a sender at the back of the head would do...

 

Sender in the CV joints has not been tried.

I just finished putting a set of gauges in my '72 2002tii.  I used the VDO gauges and the adapter from VDO for the oil pressure.  The senders and gauges for oil T and P from Bavairan Autosport.  Here are the part numbers I used:

 

oil pressure sender - 360 023

right angle adapter - 240 043K

oil pressure gauge - 350 108

oil temp gauge - 310 106

 

Hope that helps

Dear Dave

 

Can i ask you how you installed the temperature sender, and where?.... You have a working oil warning ligth?...

[carpediem]

I installed the oil temperature sender in the oil drain plug.  I found a VDO sender with 1/8" NPT and tapped a hole in a new drain plug.  I've only driven a couple times since installing them, but I can see that the oil temp is much lower than the water temp.  At least for the trips I've done so far.

 

The VDO oil pressure sender has two terminals.  One is for the oil warning light in the dash.  Just connect the original wire to this terminal.  The second terminal transmits the pressure signal to the new gauge.  You have to run a new wire for this.

 

The water temperature sender was mounted next to the stock sender.  This required taping a new hole in the little water manifold at the front of the engine.  We pulled the manifold off to do this.  The advantage of this approach is you can keep the stock sender and dash functionality while still getting very accurate temp readings on the new gauge.

Here's a picture of the water temperature sender installed. That's the stock sensor on top and the new sensor in the side.

Thank you very much!... USEFULL

 

[Xhrismar]

Some of you know which is the low alarm value for the original sender?

 

[TobyB]

Very low (too low)- 8 psi?

 

20 works well on a healthy motor.  Keeps it that way.

[halboyles]

8 psi!?  My peesi is higher than that.

 

Is there a stock sender that has 20 psi as a trip?
