New Air compressor issue?

Both check valves seem to be working fine. The internal one on the air dryer and the one on the tank. Idk. Also zero issue before this new compressor. Everything aired up great. It was just pushing a bit of oil so I wanted to replace it before it got worse.

 

No air leaks found. I think these unloaders are not working properly. I am going to pull them out and put the old ones from my other compressor in here. I have pulled this cover like 3-4 times and these unloaders don't operate that smoothly. The first time one was stuck towards the top. It's the only thing that makes sense at this point and I am going to do whatever I can do not take the pile of junk off again. I don't have the time to waste another day dicking around with it.
