Is that oil on the cooling fins or did someone spray it with undercoating?

Yes, and 100% verified by doing a google search for "Porsche 914 oil temperature gauge sender" (tons of pics).

[911 Rod]

I'd say pull the motor and go at it.

The low pressure light is not working and the druck is no longer doing anything although it was moving up and down along with RPMs before I started fooling with the gauges. I still think this is related to the red double wire"lamp cord that is in the first few photos and then goes up to where the gauges are......I have the ends of that one but dont know what it is measuring

Queenie, can you find where/to what the lamp wires are connected in the engine bay? That would really help with identifying them.

you mean in the picture above your comment?
I think that is scraping evidence from where this is low point of car?

This photo shows the furthest in that I can see the lamp cord going.

Thank you - I will try to put a trace on that wire and make sure my gauge is hooked up correctly - seems like it is in a position to get scratched up hanging under the car like that!

Yes, that picture. I'm looking at what's on and between the cooling fins. Should be a nice silvery color & clean to help in cooling, but what I'm seeing is either covered in oil or overspray. If it's overspray from body undercoating, get it off with carb cleaner or something similar. If it's oil, get it off with an engine degreaser or use a couple of cans of brake cleaner on it. Once cleaned, if its an oil leak you'll be able to pinpoint the source. Is it dropping any oil on the ground?

We should be looking at something more like this:

wow - big difference. I see what you mean. Will investigate and report back. It isn't dripping oil...I think it is the undercoat but I will check. thanks

Well my new fuel sender works! Just took around 15 minutes to find the safety pin that had to be removed. It was under the warning label Then 5 minutes to install.

Next item - Can I just put this oil pressure sender:
Part #: PEL-PP903488
Where my current "idiot light" wire is? so that my oil pressure works?

[rwest]

Victory is hers!

Good job.

I think you want a dual sender so the dash light will still be operational to get your attention.

Not sure if this will work on that engine or not?

[Rawknees'Turbo]

The sender also must be compatible with the gauge (based on the gauge's part number). I don't know exactly how to determine that, but other members do, such as Bruce/ Flat Sixpack (or something like that). Maybe start a new thread asking how to tell which sender you need.

Also, the sender is to big for the opening in the sheet metal where the idiot light currently is, so you will either need an appropriately sized piece of threaded pipe to raise the sender up (I did this with a 914 - took sender to a hydraulic hose shop so they could see the thread size, told them what I wanted, and they made an extension pipe for me), or enlarge the opening in the sheet metal/engine tin.

pelican says it is compatible with my engine......do you think it would fit if I unscrewed the spade?

My gauge number is 911 641 103 29 0003

[rwest]

Can't really tell from that picture, but is it attached to another piece rather than the engine? I would expect it to have some sort of way to get a tool on it?

[Rawknees'Turbo]

Queenie,

It will absolutely, positively not fit in that space without making one of the two mods that I mentioned above. That is not a guess on my part, but am speaking from experience.

Pelican says it is compatible with your engine because it is, but that sender is made for an aftermarket, VDO oil pressure gauge - not the 911 combination gauge that is in your car. You need the sender that is specific for your 911 gauge or it will not work (a two-connector sender, like Rutager mentioned, or your low pressure light won't work - not sure if that is even available for a 911 combo gauge, though, as many 911s use two separate senders, in different locations on the engine, for that).

That is a basic pressure switch - the wire connector is sticking out of the top of a small, hex head fitting.

[Rawknees'Turbo]

^^^

And the switch is screwed directly into a threaded hole in the case (no removable fitting block there like 911s have).


Queenie, if you want to, you can test the switch with your multimeter - test for continuity between the wire connector and the engine case - with engine off there will be continuity, and with engine running, no continuity as the switch contact points will be opened by the engine oil pressure.
