1- My 94 camaro v6 3.4 has something wierd going on, when the car is parked or just stoped the oil gauge goes really low almost into the red zone but the oil in the engine is full. low oil does not go on.
2-The gauge for the heating goes up when the car is stopped or parked and goes back to normal when it is moving what is going on.
Please let me know, darkchild_iha@hotmail.com if any one could call that would be great 209 585 7171

It is pretty much normal for the oil pressure to drop down as the engine temperature goes up. The oil viscosity thins as it warms causing the oil pressure to drop especially at idle. You are okay as long as the gauge doesn't go into the red. Which viscosity oil are you using? If you want to boost your oil pressure, try using a thicker motor oil to boost the oil pressure. As far as the temp gauge goes, it is normal for the temp to rise when the car is stopped and drops as you move because of the movement of air through the radiator. When you are stopped and the engine is at idle, the temp gauge will rise about 3/4's of the way and then drop to about 1/2 way because the electric fan will kick in and cool down the engine temp. This is normal.

Anything over 10 lb is fine at idle
Then approx 10lb per 1000rpm going up to 55 to 75 lbs.
Anything significantly lower than this indicates worn bearings and such, or an oil change is way over due.
Use the correct grade for your weather conditions.
Bumping up viscosity to get pressure simply hides something that is wrong..and when it comes to oil...both pressure AND volume are critical.
A high volume low pressure and engine can surive, even 5 lb at idle is ok.
but high pressure, no volume engine will die.

if your car has an engine driven clutch fan, check it. With the motor good and hot (but the engine off) it should be pretty hard to force to trun by hand. With everything stone cold it should be easy.
If the fans are electric make sure they work, and work right. One of the pair, or a single, will go on when you turn on the A/C.
oil pressure is normal.

Ever since I have had my chev with a clutch fan, the orginal got sloppy, replaced, this last one sloppy but the engine was reved the hell out of a killed those bearings. I havew often checked the fan clutch and never seen them hard to turn...a little drag is about it.
I have wonders about holding on to it when then start the engine ...but neber been game to...
So as it if testing a clutch fan under these conditions I have my doubts
