Hi all. When I shutdown my Kohler engine (on Cub Cadet tractor), I hear what sounds like air rushing/leaking that pulses in sync with the crank (5 second video link below). It may be happening while it's running too...just not sure I can hear it. Has been doing this for a few months. I don't think it's affecting the power output, but not certain. Any thoughts and comments would be greatly appreciated!

Or a loose spark plug or a loose muffler or the breather fallen off ( a bit harsh for that )
Pull the spark plug take photo & post .
Blown head gaskets externally generally cause a lean burn so the plugs are near white

Thank you. Do you know...is there anything like a Haynes or Chilton type manual for Kohler engines? I've done a head gasket on a car before using one of those manuals, but can't do it by heart. I did find a "service" manual for this engine, which goes through disassembly/inspection/reassembly. Read through it. It leaves a few things abiguous. But is there anything better anywhere? Thanks again.
Thanks, it is an old thread but trying to remove the baffles etc to confirm is difficult. I have no oil residue or smoke....just that sound which sounds like a compression leak you get with a loose plug (checked the plugs are snug and clean) or bad exhaust manifold/gasket. Cheers.
