First I was plowing snow today and noticed that the tractor was dripping oil. Best I could see without taking things appart it looked like the oil was coming from the tube on the valve cover. any thoughts on why? Second there seems to be a fairly loud clackety clack noise coming from the valve cover area. Like maybe the valves are loose? or slapping the seats ? any thoughts on this also? And finally does anyone have a source for a hh160 manual? thanks.

http://www.smallengi...Information.pdf Hear is a great manual.Hard to say on the noise, But I would pull the side cover of and check what is going on in there. turn the engine over when the cover is off ( engine cold) and check the valve lash ( gap). maybe a valve spring retainer fell off? Good luck.

I think the manual covers 3 to 11 horse motors, the hh160 is a 16 hp motor.

My Sears ST16 has always expelled oil out the crankcase breather. If I mow with it or otherwise use it for more than a few minutes I wear old boots. :( The thing runs/sounds great but somehow builds too much pressure in the bottom end. I'd also like to know what you find as the culprit.

It could just be that the breather filter inside the valve cover is dirty. That will often allow oil to back up there and then leak out.

Thanks for your reply, I took the valve cover off and could not find a filter of any kind. if there should be one do you happen to know where it goes?

Did you check the valve clearances while you had the valve cover off?
