    Default John Deere 720

    I have John Deere 720 that blows smoke out of the oil cap on the side of the tractor and there seems to be alot of pressure there. I tried a to put a breather on it but it didn't seem to help. Is there any ideas that I could use and try to fix it.

    Well all you can do is a breather cap which you did.You are having blow by must likely one of your valves isn't seating right.Most likely u have carbon build could try a oil additive to the oil that helps clean the engine.other then that you have to do a compression test to see which cylinder has less.
