Possibly. Don't drive you car if can, wait till people give you an answer. If you drive it, you'll just do more damage than it is.

the only thing i could think of is maybe a chunk of carbon buildup came off and got caught---- i have heard of stock pistions on turbo cars comming apart and damaging the top end but cant see that happening but its possible--- pull the spark plug and look inside the cyl and see if there is anything in there or if your pistons are damaged or missing the skirting

did it rattle when you started? if you could that is....

and if it was a dropped valve seat, you'd hear it banging around in there constantly, until it got into the engine and then you're screwed [hihi] I thought I had the problem, but all that was wrong was the starter motor...the gear didn't retract quick enough.

check the ribs on your timing belt, if they're worn or missing, then that might be your problem.... yes the car does run with the dropped seat, but if it goes into the engine you're screwed.

mmm........by the way, what's the compression in your other cylinders? no way, NO compression in the number 4 cylinder? (I believe it starts at the passenger side, next to the timing belt.....)

yeah tore it down yesterday and found some damage to the piston and head like there was metal slapping around but the cyl. walls looked okay so i filled the cyl. with oil and none has leaked down...pulled the valves and found half a seat left and have no idea where the other went but when i tipped the intake manifold up it sounded like some metal fel out is this possible? and is there any upgraded valve seats i can get put in?

damn lol.......sorry I kinda forgot about this.....

BUT, when I thought I had the problem, I'd done some research and found some replacement valve seats, but I'm not too sure on the quality of them..... BUT if you can get the head fixed or replaced, as well as the piston...... I think you'd be ok.

IMO, you'd be best off replacing all the valve seats, cause they had some sort of manufacturing defect or something like that, so if one broke, the chances of another going will be pretty high.
