Strange oil temp and press. problem
I recently fitted 3 Defi Gauges which were purchased NEW from Japan to my JDM MY06 STI(Boost, oil temp, oil press.), so i dont think that anything is wrong with the gauges..
The problem seems to be that the oil pressure is (when hot) under 2 bar ( about 1.8) and the oil temperature never goes over 80degrees celcius...
is there anything wrong with the car and will any of this cause me any problems in the near future? Btw, the oil temp sensor is plugged in a sandwich plateover the oil filter, while thepressure sensor is plugged where the stock sensor used to be(under the alternator)..
Ps. I use valvoline semy synthetic oil and just recently i had an oil change...

You don't say at what revs you are getting 1.8bar! If it's at idle, it's fine. If it's at normal driving revs. eg 3,000 there's a problem!
80c is pretty normal but will usually go higher when using the performance or if stuck in traffic on a hot day. It may take up to 4-5 miles before the oil reaches it's normal operating temp.

its at idle that it sits at 1.8bar...
however the oil temp doesnt go over 80 degrees no matter how much a try it usually sits above 72 degrees when normal driving and can reach 76-77 tops when driven hard... today that i got 80 degrees the outside temperature was 40 degrees celcius and i was driving quite calm in fear of detting occuring...
is the oil "working" correctly at this temperature (70-75 degrees) or is there going to be a problem with it?

Sounds like a sensor/location problem to me, I have a mate with an 06STi and his ran at 95-100 deg (up to 120 on track) until he fitted an oil cooler to get it down to 80 in normal use. Your oil temp can't really be as low as your gauge says as it is bound to run hotter than the cooling system as its nearer the source of heat and only gets its cooling from said cooling system unless you have an external oil cooler.
I read that your sensor is fitted to the sandwich plate which may be subject to some local external cooling of the sensor. I believe oil temp sensors are more usually fitted at a port above No 3 cylinder.

I may be wrong on this, but i have always been under the impression that if you use a sandwich plate, the readings may vary.
Im lead to beleive this is due to this being the cooler part of the engine as air flows under it, and cools it as it passes?
