T-30 pull up the relief valve to get it to run
I have a T-30 30 hp when you start it up in the morning it will take right and run perfect however after that for several cycles you have to go over and pull up the relief valve to get it to run at full speed! And suggestion on what might be wrong?? Can you email at firstname.lastname@example.org with your thoughts
T30 242 water in oil and oil in the unloaded valve
I have had this compressor for 12 yrs. with no problem.I have an old t30 242 that has never been rebuilt, it started getting water in the oil lately and oil spitting out of the unloaded valve. It is home used, so it never really gets to hot except when I use the sand blaster. The shut off pressure is set at 160. A buddy of mine said it was really oil because it is not grey but a greenish color paint pump. What could be the cause?

IR Type 30 isn't building up pressure.
The model is 253D5
A couple weeks ago it was building up pressure to 100PSI then working real hard, then 80psi, then 60psi, and now it's at 50psi and it works really hard. If I hook up just the smaller side it works fine. I've disassembled everything and the oil is clean, cylinder walls look good, and the piston rings are intact. There was of course some carbon buildup, but I cleaned it off. I noticed that 3 of 4 of the reeds are easy to push up, could this be my problem?
The model is 253D5 and it has a newer motor which has been tested and works fine, the pressure switch is also working properly.
It looks like a 2 stage compressor. Have you checked the intake valve on the line from the first to second pumps?
If it is a two stage, the intake valve on the second stage may be crudded up, and that might be the problem.
Good that you know the motor is OK, as lugging on increasing pressure is an indicator of motor wearing out, or a problem with the run capacitor too.
