dropped valve

[aitkindrum]

just bought '99 griff with 12000 miles from dealer with full service. drove 35 miles and suddenly engine vibrated and would not idle. as sunday only salesman working told me if poss to drive home which i did further 10miles. car collected and dealer eventually states 'dropped valve' possibly bent not broken. don't know yet whether inlet or exhaust. am bit pissed off. couldn't afford car in first place.
dealer obviosly fixing engine however when i go back to bahter wonder if anybody any experience of similar in relatively young griff? once mechanics fixed is there any likelyhood of associated damage i.e. crank bearings, cam, catalytic's etc? anything else i should be aware of? ta

My 1992 400SE developed this problem 3 months into ownership 5 years ago. I ignored it .. (couldnt afford to get it done) the resiult was a new valve, valve guide, valve springs of and a bitt of £600 from Wedge automotive .... all back in 1997 !

Good luck !
