90 psi is too much pressure at 5500 RPM. 70 is plenty. I'd want to verify that reading, and if it is accurate, I'd find out why.
Also, fixing the mounting of one of my mufflers. Ignore the dead bird hanging from the frame that traveled down the drag strip for several passes with me
Easy to see 90 if the oil was not warm even with 60lb spring. Sounds like you revved it to 5500 before OIL warmed up. I've seen oil temp at less than 100deg when water was 180.......
Was that oil temp in the dead of winter? The plan for today: fix the console brake light thats stuck on the ashtray that keeps self ejecting the string tied to the climate control lever is broke, did anyone say working A/C? buy another new belt cause I might have fried two of them-power steering belt was nearly falling off it was so loose
John drive the car until you see your 18 psi at idle. Then hammer it and see where the pressure tops out.
Ok Larry it shows 70 psi when I’m at 18 psi for idle. Is that enough pressure to turn the engine up to 5500? And sadly, the A/C does not work.
No....even in warm weather the oil will take a while to get anywhere near the water temp on first start up. If you put an oil temp gauge on you would see what I mean. One of the top racers I know uses a pan heater for the oil even in summer. Between rounds especially if windy the oil temp will cool off. The guy is deadly consistent....running alcohol helps him too.
Yes and thats only 5 quarts... Look at these dang fools with diesels 3 gallons . Start and roll coal..
How can I try and get my A/C to work? I’m able to flip the switch but I can’t get the compressor to spin. Is it automatically locked and won’t spin without power to the switch?
Correct John, no power no clutch kick-in. Try a jumper wire from the + battery post to the incoming wire with a cotter pin pocked into the terminal on the compressor to see if the compressor kicks on. You will see the other end of the wire going to a ground. Make sure that's not broken 1st.
Have you also verified the system is properly serviced? I have never worked on the a/c of an older car but I would assume your car has a low pressure switch to prevent clutch engagement when there is low or no refrigerant.
X2 If you do jump the clutch as mentioned and it kicks in if there is no cold air coming out in a minute or two stop activating the clutch. I'm pretty sure you can have problems if there is no refrigerant in the system and the compressor is running.
Yeah, sorry John I forgot to mention that, BUT after doing the same thing for MANY years you just ASSUME> ME BAD. Without Freon the system has NO WAY to circulate the oil in the system & you know what happens with NO OIL.
