Re: [ST] End to Crank story (hopefully...)

[Neil Lindsey <Neil.Lindsey@xxxxxxx>]

Is this true?

"The motor is not the type where the pistons come into contact with the
valves"

I understood that most modern engines (955 included) were on the
'interference' type, where this IS possible if camshaft/valves and
crankshaft/pistons get out of sync.

To me it sounds more like whatever broke did not upset
camshaft-to-crankshaft timing.

This failure is on an '02 Sprint right (therefore the newer 955 favour)?
