Hi all,
I have a Manual GPX.
Really need help. For past 2 days the normal tappety sound has become a LOT louder & I have lost power.
I have done a full oil change, and put some top end treatment in thinking it was a tappet issue - but that didn't resolve.
On further investigation it seems that the noise is coming from the rear bank of cylinders. So from here I haven't a clue where to go next. The noise pretty much subsides when idling.
Any suggestions? Anyone faced something similar?
If it's something like a cylinder or cam prob, anyone have an idea how much this would set me back?
Any advice appreciated.
