I have taken the cylinder head off because of loud banging and pinging in the motor, there were peices of metal on the #4 piston?? the valves were both fine. I have only had this car 3 days, literally i know nothin about them, i do know a lot about cars tho, mostly imports and small 4 cyl's. do the sohc 2.0l's have valve seats?? it looks just like that but hammered into about 30 peices. judging by the cracks on the peices, i think it looks similar to a valve seat...

the tensioner could have done a lot of this...

Any replies would be great.. tomorrow is shopping day....
