David, I appreciate the reply. I tried the injectors, can't tell any difference with the knock. The only time I ever hear it is when for example I am backing the trailer in the barn idling along in high range reverse and it lugs a little bit. It doesn't always do it though, but when it does it has a fairly consistent rhythm until the engine speeds up. Oddly enough, it is not as noticeable when the engine is hot as it is when it is cold. I know the engine has had at least some work done to it, looking up through the oil screen hole it is as clean as a brand new one, and I've never seen oil stay so clean in a diesel. As bad as I hate to, I guess I'll send it to the shop and see what they find.

Hi Brian,

I am not sure where it is, but I am pretty sure the oil relief valve is supposed to be adjustable in your engine - it is on my MF-65 gas engine.. The oil pressure will suffer if the relief valve spring is worn/slack. If you can locate it in your manual, you might be able to either shim the spring to increase pressure or replace valve and spring. I did this when I rebuilt the engine in my JD450 crawler loader. The oil pressure now stays above 40 psi even after working the engine hard for a while.

It might be worth checking it out before going to the repair shop.

Re knock, are you sure one of the injectors is not playing up? Dribbling or sticking needle valve in the injector can give a knock that sounds pretty bad and make the engine knock quite a bit, making it sound like serious problems.

HTH

John
