Air Compressor Bubbling and Valve issue.

[RSVRMAN]

I'm a bit new and new to the forum, so I apologize for the questions if they seem odd. I have never owned an air compressor this size before. I have owned a 25 gallon direct, but not an oil. I recently bought this air compressor and have a few questions about it. I have tried to call the manufacturer today, however nobody answered the phone after several attempts which led me here.

First question. In this picture is the oil fill "breather". It keeps bubbling. I know if I remove this part there is a constant air coming from inside and that the ball bearing I would believe should stop this air flow preventing loss of compression in the air compressor. However it just keeps on popping or making a bubbling noise until the compressor is out of air. This would leave to believe there is too much blow-by? from the piston or valve. So I guess I would ask is this normal?


Second question would be for the other pictures. This valve I will call it just leaks. I have tried adjusting the pressure screws and it just leaks anyways unless I leave it unplugged as it is in the photo. It is the one that I'm pointing with my finger and goes back into the compressor. I unhooked it and the compressor seems to work fine, however I believe its important so I'm waiting on some answers before I use it again. I have looked underneath where this valve screws in and it is properly aligned, there is no problem with the valve itself. It's just that the object that is supposed to push on this valve incase of an incident is too low? Sorry for the poor terminology this is new to me.

Any answers would be welcome. Thanks

I'm wondering if something in the pump is leaking and forcing air out through the crankcase filler. That could be rings, or the head might not be bolted down all of the way. Those are the only points of failure I can think of, but there could be others I'm not familiar with.

Yeah I know its a broad question. I will go over it again and re-tighten everything. It is bran new so I would think it should be factory tight, but I know how well that can go.

I was wondering that once it is not running if the valve entering the tank is supposed to prevent that blowback. The line that straight feeds down to the center of the tank.

If it's new, you need to warranty the problem. That pump appears to be a Sanborn pump. I have one identical to it and it doesn't "bubble"

It possible there might be to much oil in the cylinder.

If the check valve is passing it will let air pass at the needle in the pressure switch. This is to relieve the pressure on the head for starting. As far as the oil breather issue I can't help but leaves me to believe it is something to due with the other problem. As stated WARRANTY issue.

Thanks for the help. Will just call to see if they will replace.
