    I am buying a 26hp EFI 2001 Kohler engine that is fouling the left plug. I have been told so far that it could be rings, head gasket or the valve seals. My plan is right now to try and change the seals first. My question is first can you do it like in a car by pressurizing the cylinder and removing the valve spring and replacing the seal that way or must the head be removed to do it? Also, do they just slide on the valve or do they need to be pressed in? Do they require any special lubrication? Can you think of anything else that will cause one side to burn oil?

    Any help will be greatly appreciated!

    Thanks, Ed

    The head gasket is your problem. Kohler has had major issues with their head gaskets blowing out.

    The apprentice has already answered, But it is most likely the head gasket.
    It would show up for sure if a cylinder leak-down test performed.

    As far as the valve stem seals are concerned, Yes they can be replaced same as on a automotive engine and they look similar to the auto type. Just a film of 10W30 oil before installing.
