    I just changed the oil in my Kohler 22hp Command Pro, and now the engine is knocking...Sounds like it's coming from the ohv cover, I'm not sure what it could possible be. I've never had this problem before, it almost sounds like there is just no oil pressure??? Please let me know if you guys have any ideas or have even heard of this happening before....This engine is only a couple years old and I have kept up on the maitenence routinely. Thank you very much for your ideas

    what oil did you put on the engine and how much? Did you change the oil filter?

    LilB281 here again...I put 10w30 in this and also changed the filter...i put just a little under 2qts, and the stick reads right on the full mark.

    There is air in the lifter as khouse said, Just run at idle for about 15-20 mins. and it should work it's way out and quiet down.
