Hey Roger, it's me again.You remember that 5120 I've been buggin you about forever?Well the guy I sold it to said that it's not building up very fast at all now, like it did?I've not looked at it yet, but I was wonderin if you had any suggestions where to start lookin?He said that he has an automatic drainer, and it is got alot of oil in it?Do you think it might have broken a ring or somethin?It was workin fine a few months ago, he uses it in his factory which is seasonal, so it's not been used since last year, but it has been inside, and as far as I know it's not been messed with.I was wonderin if someone might have turned the constant run valve, and it might be stuck in the unloaded position? Thanks in advance for any help.I really appreciate it!! GOD bless

First thing I'd do is put some 100psi pressure gauges in the intercooler safety relief valve ports and see if interstage pressure is ok. If it is very low, or zero, you have unloader problems or valve problems. If there is a constant run valve on it, turn it off, although this shouldn't hurt output if it is operating normally. Check oil pressure as well.
