My car typically runs about mid-80's on a typical day, it will get into the 90's on a really hot day, AC on, slow traffic.

DaleClark Is this the thermoswitch you are referring to? I just want to be sure I order the correct one. This is from Atkins Rotary.

That's the correct part. Ray Crowe probably has it cheaper than that.

Here is the readings I get from the sensor check.
The VMOP only shows 1.19V and when I rev the engine it barely moves to about 1.34V to about 1.45V. Should I be concerned or is that normal operation? I think the range is 1 - 5V during normal operation.

Or should I be premixing just to be safe due to a possible faulty OMP?



Cheers.

The yellow and black vac line is what runs to the oil injectors. (Ts out to two lines). Fed from the turbo air inlet. The oil lines themselves from the OMP seems to have oil in them.

A faulty OMP will typically show up as a reverse highlighted row on the Commander. Similar to how the Fuel is highlighted in the picture.

The OMP's really are hardy and work well as long as the wiring and plumbing for it is all hooked up and good. It can be beneficial to mix a small amount of premix just to make the engine happier, though.

Thanks a lot Dale as always.

I did premix just to be safe. And the fuel is highlighted since I switched to the rywire harness and the fuel temp sensor isnít plugged in. (No plug for it)

To be sure and for the break-in of the engine I will continue to premix the fuel.

Cheers
