Air compressor overhaul or replace

Hey y'all, thanks in advance to all who respond. But I got an air compressor that's giving me morning pains when cranking up the truck. I have to wait about 15 minutes to raise the heat high enough (150f-175f) to get my air compressor to start filling up my air tanks. The thing is, once they're filled up for the day I have no issues at all. But since the weather is getting colder, I'm having to take longer and longer to warm it up to get the valve to open/close to get air flowing.

my guess is that there's soot built up in the release valve that opens and closes and it's having to be heated up to activate properly.

so that leads me to the question, should I just get the overhaul kit and go for an overhaul, or replace the whole air compressor? One is much cheaper than the other of course laugh out loud.

I might have to just chunk up the couple grand to do it all then. I've been putting this off for months now laugh out loud. It's just really becoming a pain as this cold weather sits in.

 

Lol yea it's about $1100 + 4.5 hours labor

 

No I haven't had anyone check that. That's what I think it is, the unload valve. What should I ask when I go to get it checked? I was also just checking the cummins insite on it, and they're talking about;

Replace the air compressor air cleaner (if installed). Check the air intake piping. Check engine air intake restriction if the air compressor inlet is plumbed to the vehicle or equipment intake system. Refer to the OEM service manual.

 

I have a good shop in Texarkana but that's like 300mi from my home laugh out loud. I'm surrounded by crooks laugh out loud, but I have a Napa big truck service center close to the house that works on all the farm trucks, then a peterbilt and Cummins in Jackson MS. It just seems like when going to a peterbilt and if they don't know you, it's just a waste of time to get them to check something when you already know they're gonna try and tell you to replace the whole part, then charge you for inspecting. You know the typical krook mentality. I try not to pre-judge these shops, I just keep my guard up around them.
