Briggs OHV & Vanguard / Intek Block Failure.
« on: September 22, 2015, 07:11:14 pm »
I had a catastrophic block failure over the weekend. Was leading the race when the engine grenaded (or so I thought). This is a 49 block with Arias flat top forged pistons. This engine has ran for 3 years with synthetic oil change every other race. I for the life of me don't know what caused the failure. Luckily the only damage was the block and sump. All bolts were still tight in heads and sump. This engine routinely sees 7000 rpm. Big 2 barrel carb, custom Isky cam and..... STOCK 49 rods. All survived. pictures included. Anyone with some ideas?
