Have a JD317 with a noisy engine.  I know a KT17 series 1 is a bad engine and they are known to take out rods. My question is this, What does it sound like when the rod is bad? For example does it  knock or is there no warning. I've got a noise in my 317. It's loudest at idle and sounds more like a loud tick or possibly an exhaust leak rather than a knock. It's not really audible when you rev the engine up. Just wondering if anyone has heard one of these when it's about to toss it's cookies! This engine was supposedly rebuilt by a PO at one point, but I don't know what that involved. It's probably got a lot of hours on it and was used to mow a large property.

Any different hot or cold?  Are the valves adjustable like in the K series? If they are try adjusting. I think it may make a difference how the rod is going, worn out, rod bolts come loose or to tight from no oil lube.  Maybe piston slap. Wrist pin worn. Exhaust leak like you say. Try plugging the exhaust and see if noise gets louder. Remember I am not a trained engine mechanic.  Noel

Loud tick sounds like valves I don't think there's a lot of lead time with rod it just snaps

I don't think there is much difference hot or cold. I will be checking the valve clearance. I don't think they are adjustable like the K series, which is a really nice serviceable setup. I'll have to look at the service manual to see what's with the valve adjustment.

One of the ticks I've heard was a split piston on a old Kohler single.  Hopefully that's not the case here.

I guess this really isn't a fair question. There are so many things that could be wrong. I'm actively looking for a newer Kohler twin to replace it. I'll likely end up having to buy an entire tractor to get one. Not much in the way of used engines for sale around here.
