Oil Level - Idiot Warning Light

[cheekychimp]

The two ports on my oil filter housing are currently occupied by the SPA oil pressure and oil temperature gauge sensors.

I realize that these should give far better feedback regarding the oil system and make the idiot light redundant but is there no way to retain the idiot light in this situation?

Does anyone run either of the gauge sensors from another location and is the filter housing the optimum location for both?

People have run pressure gauges from the stock turbo supply on the right side of the head.

Otherwise, you'll either have to put a "t" in the system somewhere to allow an extra port to be used, or re-configure the dummy light.

 

is the head an accurate source for pressure. or would the oil filter housing be the preffered spot for a gauge.

I have a dual sender for my gauge. It feeds pressure to the gauge and has a switch you can connect to the stock idiot dash light. I think it trips at 11 psi. Single port, two functions.

I think it's this one, but I bought it a long time ago so it might be a little different:

Paul you might consider a larger light and maybe a 20psi sender. I think that the factory light is a really low pressure sender. You can get a separate 12v bulb and mount it in a blank switch on the dash, get a small AN4 t fitting to run the sender off the turbo oil feed line.

You can get a brass "T" to plumb two fitting off of one of the 1/8" pipe fittings that you're currently using.

Thanks guys. I'll look into some of these options. Apparently the SPA sender was a different thread so I'll need to find out what the ports have now been tapped to or go with Alex's suggestion.

Alex why did you advocate using a separate dash bulb, could I not simply install the bulb in the current idiot warning light location and just run a wire to it or tap into the existing harness with the new sender?

I don't see any reason that you couldn't buy a 20psi sender and wire it to your stock bulb. Keep in mind, you will very likely go below 20psi at a hot idle so the light will come on at that point.
