Hi everyone, 73 GT the correct VDO oil pressure sending unit: What other cars does it fit?

Eric;
You can buy a new one at eGauges.com - VDO, Auto Meter, Defi, Isspro, Cyberdyne and Classic Instruments Gauges

This is the correct "egauges" OP sender, 1/8NPT P/N 360-009 . . .

. . . and this is the correct "egauges" adapter to adapt the OP sender male 1/8NPT fitting to the block's female M14x1.5 threaded OP hole, P/N R7963

Hey guys thank you for the response, I am wondering what other types of cars does the unit fit.

I'm interested to know if these sendors can be used irrespective of engine capacity. My GT's running a stroked 2.2 block, now 2.4litres, and despite the engine having done maybe about 2000miles it's always shown an oil pressure of about 3.5bar when hot, but at tick over the light is always on and showing less than 1bar.

I have no smoke, good performace, at 190bhp, but the light and low pressure are driving me crazy.....HELP!

The VDO sender listed is wholly dependent upon the original gauge being used - the motor size does not matter.

That being said, they are old gauges and may not read very accurately.
Pays to (temporarily) fit a mechanical oil pressure gauge to confirm oil pressure - I guess the gauges can be adjusted to show correct pressure ... by a VDO agent.
.
The Opel oiling system is very much like the Rover V8 one - low pressure with volume, rather than high pressure.

A stronger relief valve spring will not increase idle pressure unless the relief valve is not seating properly. The 'plastic' relief valves on the pump base plate are known to 'cook' and stop working properly. Best to use the cast iron Opel diesel one - if you can find one. OR try a new oil pump plate.

Also check that the 'old' relief valve in the front timing chain cover is sealing - it is disabled (with a heavy spring) in later motors that use the relief valve on the oil pump.

A bit of 'crud' holding either one a wee bit open can reduce idle oil pressure - as can a worn oil pump plate, gears or housing. You may be able to find a 2.8L six cylinder front cover over there in the UK - they fit and some have recently turned up new.

And the answer you gave was incorrect, the VDO sender proper for a 1.9L block is PN:360-028.

Do you have the gasket installed between the oil pump bottom cover and the timing cover? Later engines such as the 2.2 and 2.4 are meant to be used with no gasket here (unlike the earlier 1.9 and 2.0 litre versions). The added thickness of the gasket will do exactly as you say...low pressure at tickover speeds, but normal pressure elsewhere. Just a thought.

. . . one-piece OP sender (360-028, $76.75), yes, but my post included a thread adapter (R7963, $6.40) along with the listed OP sender (360-009, $25.90), my preferred combo for cost reasons!

MY approach to replacement parts, with very few exceptions, has always been "function/cost" prioritized, but I guess it's up to you to decide if it's worth paying more than double to accomplish the same thing!

Save more money in the long run buying the right part!

If you go the thread adapter route look out you
don't overtighten (experience talking here) it's
made outta brass and will twist off slicker'n owl
poop. E-gauges does a flat shipping rate of $11
so that makes a $6 part pretty expensive, (dang
it.)

. . . guts of both senders and oil feed hole sizes are identical, only the mounting thread sizes differ, which is taken care of by the thread adapter . . . you're essentially paying $34.45 just for M14x1.5 threads!

At your "right part" price, you could buy TWO "my parts" senders and adapters with money left over!
