It had a piece of the piston hammered into it, when removing the plug it came out hard and cut new threads on the piece of the piston that was stuck in the plug. Im sure it looks just like your posted pictures...The catastropic failure gave no warning at all.
Do they use cast or forged in the remanufactured engine? |

Engine temp. was around 160 and oil pressure 45 PSI. I stopped right away and raised the engine hatch and noticed what seemed to be a small puff of steam belch out of the flame arrestor. I attemped to restart engine and had an uneven cranking RPM along with rattle every revolution. I checked the oil then and it was about 6 inches over full then found the coolant reservoir to empty.
I had read about weak pistons on the 496's on modified engines, has their been much of a problem on bone stockers with 40 hours? I am assuming the piston came apart and went through the cylinder wall. Are their certain year engines better than others? which state you located in? Because i know where their is one sitting in a garage for the pst year, believe its a ho. ill see if i can get yo uthe guys #.. |

Personally, I would not reccommend re-using that plug! :evilb: Sorry dude, bad joke. |
Hope you get it going soon. I lost 2 of those engines then Merc seemed to have worked it all out. Guess not. Im going to old school 525 carbed that I can wrench on myself.
