Ive got a really bad ticking coming from my passenger side rocker cover...and it sounds like its running on 7 cylinders...the RAC mechanic said either a valve is broken or bent or that a valve spring has snapped....does this sound right??....anyone had this problem b4??

It could be a bent valve or broken spring but you won't know until you pull the rocker cover off, but its a fairly rare problem unless you have really over-reved the engine. It could also just be that one of the lifters is not filling with oil or a number of other things. Luckily the passanger side rocker cover is easy to get off, you usually don't need to remove anything but the intake piping and then its just the 6 rocker cover bolts.

i found the problem...its a snapped valve spring on the very front left cylinder....its strange but, because i wasnt even hammering it before or whilst it broke...ud think it would break when its under a heap of strain...im getting a whole set of new high performance springs which will let the engine rev a bit harder for $250 fitted...

Same thing just happened to me!
No 6 exhaust spring broke, and they were crane singles.

Make sure you order roller cam springs as flat tappet cams don't have quick ramps...I'd use double springs for sure!! Better for spring harmonics etc...

Yes - get doubles!!!
I ordered doubles when I got my cam done... However, somehow the doubles I handed to the mechanic never made it onto my car, and I got singles put on (and hey - like I was gonna take off the rocker covers to check) I snapped number 7 one day - wasnt even giving it a hard time - just cruising on the M4 under 2000rpm. I made sure I got doubles put on after that!!!
