I am the guy that posted the question. It turned out that the expansion valve was blocked. That makes sense in terms of the pressure readings. But the reason it was blocked was surprising to me. The drier failed and allowed tiny beads to flow throughout the system. I had to have the whole thing flushed and actually, it still blocked again. We finally got it though and it works fine now. I strongly suspect that the drier problem was caused by the fact that I put a lot of stop leak plus too much freon. But I am not certain of that.
any overcharged a/c system will cause high pressure
high head pressure and a higher supply temp.
The oil pump is driven by the engine. Turning the engine faster means that the oil pump spins faster, this creates more oil pressure. 80 psi is normal at high rpms, and will not cause any problems.
Yes, it is very normal to have head pressure when you need to get your molars out. Teeth pain can cause a lot of pain in your head.
Built up fluid is almost always the cause. I suggest taking a decongestant.
Some vehicles` oil pressure will do this when at an idle. This is normal, if the oil pressure does not get higher when at higher rpms then something may be wrong.
There is a low pressure switch that may be indicating lower pressure. If you do not hav eenough fluid in your system it will cause this affect.
No, the system is only checked at normal operating pressure.No, the system is only checked at normal operating pressure.
Verapamil helps lower your blood pressure. Religiously taking this drug prevent you from having stroke.
Most often, this is cause by droplets of condensed water striking the fan blade. It is normal and not a concern.
The maximum pressure exerted against the patients airway during the breath.
Yes, it can make you pass out. Or it can also cause you to go into shock, which can be dangerous particularly if your normal blood pressure tends to run lower than the average normal blood pressure.
