Default Timing belt

I week ago, I pulled out of a friends yard and got up to 50 mph and lost power. I let my foot off the gas and coasted to a stop. My question how many owners have had a timing belt break and it bent valves?

2.4 L engines are 'supposed' to be non interference, ie NO contact between valves and pistons ever possible no matter the (mis)timing, under ordinary circumstances (realistic RPM operation, conds. below insanely extreme revs causing valve float or bounce)

I think 2L are interference , guaranteeing bent valves after a belt break.
( what PT uses a 2L ? old or ex-US ones ?)


That said I looked a job ticket at a Chrysler Stealership last week for a broken belt repair (~$1500 with water pump) which claimed "possible valve damage" with no other explanation, you think they would know better than lil ol me.

PS if they put a belt on MY car with valve damage present, I would sue their pink lil pooters for malpractice. Its like given me a heart transplant sourced from a cardiac related death

The valves can collide when the belt breaks - it doesn't happen often, but it can happen.
I don't know how you can tell if the valves have hit.

point well taken - didnt think about valve to valve relations.

“The 2.4 Liter (148 cu. in.) in-line four cylinder engine [has] hydraulic lash adjusters. The engine is free-wheeling; meaning it has provisions for piston-to-valve clearance. However valve-to-valve interference can occur, if camshafts are rotated independently.”
