I'm at a friends shop and right I when I get there, one of his mechanics just pulled the head off and called me over to look at it. In all my years, I've never seen such carnage.
An interference engine is a type of 4-stroke internal combustion piston engine in which one or more valves in the fully open position extends into any area that the piston may travel into.
On yours I would think the belt may have jumped a tooth or two.
all of the exhaust valves, and none of the intake ones?
where did you get that engine, the twilight zone?
I was always told that in a case like this, the valve train slows down at a different rate then the pistons, and it's a crap shoot which ones eat it and which ones don'tGenerally how it happens, as the exhaust valves are traveling down as the piston travels up.
Most everything is going to a chain because of cam advancers/phasers for VVT are hard on chains, a belt would not survive long at all.Those high output engines have very tight clearance's. And the combustion chambers are tight. IMO the should have a chain and scrap the belts, Several modern engine families use a chain. Ford comes to mind in there Eco Boost engines.....View attachment 1715140529

I had a little Chevy aveo once, snapped a timing belt on it and 14 out of the 16 valves ate it
It’s just Human nature to want to dissect the disaster and figure out what happened.Is it really worth arguing over? It's tore the hell up. Doesn't really matter now, does it?

Looks like the belt slipped a few teeth and the exhaust valves all smashed into the pistons as a result.
And it sure as hell was not the Air!LOL!
Yep.
