Briggs 31Q777-0305-E1
Head gasket blew in 1 day after I replaced it. In the usual place where no bolt can tighten it down.
Engine is on a Cub Cadet that I bought used. Guy said the head gasket keeps blowing and he is right.
After I replaced the head gasket I noticed the push rod adjuster was hitting the valve cover as you could hear it and feel it. Turns out someone put a longer Intake push rod in. I don't know if this caused any damage other then the dent on the valve cover.
After replacing the push rod with the correct one the engine ran fine. Then when I engaged the blades I could hear a fast knocking sound for 1 second and then it goes away and was mowing fine. I mowed maybe for 5 minutes then I re-engaged the blades smoke poured out the exhaust. Head gasket blew again.
I'm wondering if the PTO is making the knocking sound and I'm not sure how to stop the head gasket from blowing.
Any information or help is gratefully appreciated.
