I'm assuming you guys are all measuring your oil temp from a sandwich plate, which you should NEVER do. Pressure either. The pressure at the sandwich plate is just that, but it is NOT what the engine is seeing. Same goes for temp, you're basically getting the temperature of the aluminum sandwich plate not the oil. Oil temp ALWAYS needs to be taken right from the sump.
Ettienne, I do hope you end up putting one on there, but please be less concerned with time (everything seems to be very time sensitive. Any peticular reason??) and be more concerned with doing it right. Just a piece of advice from someone who's done this more than a few times...
I think you are overstating your case here.... The oil pressure will largely be the same in any pressurised area of the oil system. Variances would be minimal at most, and certainly no more significance than the tolerances in the calibration of the sensor (which can vary widely), and accuracy of the actual gauge face itself (with temps showing in resolutions of 50 or so degrees, you cannot tell the difference between 210 degrees or 220 with any level of certainty).
Same goes for, and is especially true for the temp sensor (whos calibration could be out by a massive amount).
Any analogue gauge's job is not to tell you the pin-point accurate, absolute value of anything it is reading - in fact, such information would be rather useless. The point of the gauge is to give you an indication of normal (where it is when the motor is running and everything is warmed up etc) - and to tell you when the value is moving away from that normal value. Its there to tell you "oh, my oil temp looks a little high" or "oh my oil temp is really climbing", or "my fuel pressure is fluctuating" etc.... it gives you an indication as a forewarning to stop doing whatever it is you are doing that is causing the apparent problem and investigate the matter, or gives you an indication that something is or isn't working as it should: "Ok my fuel pressure rises when i increase load, thats what i'd expect...all is ok".
In short, chuck the temp probe in the port for the sandwich plate, and throw the pressure probe in there too. Sure it may be more "accurate" than putting them in the "right" places, but that kind of defeats the purpose. Hell the manufacturers themselves rarely put things in optimal places.... the stock oil pressure sensor is simply a "pressure/no pressure" sensor - if it sees any pressure, no oil light. If it sees no pressure, you get an oil light (probably long after the damage is actually done) - any part of the oil system that is under pressure will serve this purpose - so i don't think there was any great wisdom to sticking it where it is stuck.
You way is probably "right" - but i can see no tangible benefit.
A warning to everyone
There have been some posts lately in this thread that are walking a very fine line between being useful, and downright rude/inflamatory. You're on notice to behave yourself. This thread is informative, and whilst CulRidr may not be doing everything he possibly can, or probably should, he's done a lot of research, and is constrained by a budget - by all means offer suggestions, feedback, ask questions as to why it is so, but calling people n00bs, and implying they are building a grenade (which is NOT the case, this build in the scheme of things is very mild), etc etc etc is not going to fly. Consider this your first, and final warning - any more posts of this nature will result in an instant infraction, and possible editing of your post. Got that?
Good.
