Re: engine chain broke in two, wile the car wasn't movi

My 460 jumped a timing chain on rev.

as Ian feared, as did I... bent valves and smacked pistons.

My local Merc Parts manager said he had never seen any damage to aforementioned in similar circumstances, and he was right.

New chain, timed and fired up on second crank!! Unbelievable but true. (7 years between incident and replacement chain by the way!!).

Don't get too despondent... likely no damage caused.

Fingers crossed.

Don't know if it applies to the 617 but on some engines the valves and pistons don't make contact. From buckalec's reply you may be lucky.

dont forget that one thing done to the 617a to make it run less stressed with the turbo, hopefully this will increase your chances of no contact...maybe!!!

I was waiting for a friend wile the engine was running, and it just stopt right there......

One thing worry's me, when the engine stopt I tried to stard it for 2 or 3 times and I heard some noise and than it was jamed :roll: could i made things worse by trying to start the car again???

Re: engine chain broke in two, wile the car wasn't movi

Possibly...the chain probably got wedged at the bottom. When it comes to taking thigs apart, gently turning engine reverse by hand, may ease things up...just be gentle and take your time... Good Luck!
