Blown Head Gasket Problem Solved

Blown Head Gasget Problem Solved ENGINES Bruce Klosky Derry Penn : “Having had head gaskets blow twice in the 25 hp Kohler engine in my zero-turn mower I was at a loss as to what to do It always ran so hot that the muffler would glow red while moving and backfire and diesel after I turned it off The dealer told me they all do that but it seemed to me something was wrong While looking through some old auto repair manuals I read that the heat problem could be caused by spark plugs The Champion RC14YC that Kohler recommended were the same “hot” plugs used in a Chrysler 360 V-8 I was able to find ‘cool’ E3 plugs at a local auto parts store I installed the E3 64 spark plugs and noticed an immediate change The muffler no longer glows red and I’ve noticed I have more low-end torque The engine doesn’t backfire or diesel anymore when I shut it off ”
