oil pressure gauge help??
 
where can i conect an oil pressure gauge to my 2.0 zetec with out putting it in the hole for the oil pressure sending unit??

the most common place is under/next to the coil pack. their is a torque bit plug that I believe is the right thread pitch and type that is needed. This is also a port that is often used for oil feed lines for a turbo.

Okay thanks I ended up putting a T on the pressure sending unit

That can work well too.

I remote mounted mine on the bulkhead and used SS braided line from the previously mentioned port.

After researching areas to mount, the weight of the sending unit could stress the T and break.

Here is what I decided on:

I used a steel adapter fitting which, in hindsight, was a mistake. Aluminum head, aluminum fitting - why use a steel adapter and introduce problems with dissimilar metals? Just dumb on my behalf. So I rummaged through my fittings collection to find an aluminum one.

As you can see I had to grind a little off the top of the t-stat housing.

This is for a mechanical gauge which is what you want, IMO.

What right angle fitting did you use?

If you go with a mechanical gauge then you want to make sure you use an isolator between the oil feed line and the gauge. Many tracks / events prohibit mechanical gauges that are routed into the cabin that have any liquids.

Using some line to locate the sending unit is a good idea I think I will do that on my build.

1/8" NPT to AN3. Most tracks only prohibit fuel being plumbed inside the car. I am running Kevlar lined brake hose. Good to 2000psi+ and 500+. If it fails while being used to feed an oil pressure gauge, I've got bigger problems than the gauge.

I don't trust electrical gauges. They are too slow to respond in my experience and since most of the affordable ones are 90 sweep, they don't give accurate information. A gauge that isn't timely or accurate qualifies as a fancy looking idiot light in my book.

^^ usually its not the line, I thought it was the gauge that they are worried about. The gauge could fail and cause hot motor oil from spraying,leaking into the cabin.

I was looking at getting mechanical because they are cheaper and provide better accuracy and generally faster response. But was informed by some local people that the auto cross scene where I live don't allow for mechanical gauges with out the isolator / diaphragm. But the isolator drives up the cost and makes it the same price as a full sweep electric.

If your autocross club runs via the SCCA rulebook, those people are wrong. The will not allow a mechanical fuel pressure gauge without an isolator but oil is fine. You can read the GCR and Solo rules online to confirm.
