I have a 1998 FL70 with a CAT 3126. The air pressure wont build up over somewhere around 10psi and it sounds like there is air hissing from inside the compressor. I had the old governor in my toolbox and swapped that out and also an old unloader valve kit. I also noticed on oil leak on the front of the engine in front of the compressor that I haven't noticed before.
Is it time for new compressor? Thanks in advance.
