I went to look at a low hours (187) L2500 Kubota today. While I was driving it around , I heard a loud pop. Turns out the oil cap blew off. The owner and I checked the breather tube and there were not any blockages.
I then drove it for another 5 minutes. It did not blow off, but I did remove the cap after I came to a stop. It had a lot of pressure that came out. The owner took the valve cover off. There was nothing blocking the tube or the breather outlet. There does seem to be some air coming out of the breather tube, but not a lot.
I took a video of this as well as pics. In the video, I started the tractor and clicked record. So it was on for maybe 30 seconds in the video. You can see the air as well as hear the pressure when I remove the cap. I also started the tractor for 5 seconds and checked the cap, with the same results.
Is this normal? Or is this excess blow by? What other things could cause this? I am not sure wher else a blockage could be. I really like the tractor, but I need to know that it is mechanically sound as well as I can run the tractor more than 5 minutes without the cap blowing off.
