Noticed a ticking noise today from my engine, thought it was a sticky lifter!! After closer inspection i noticed the noise was coming from the air to air injectors.

When i unplug the right hand side injector the ticking stops, but when i put it back on it starts again???

Have swapped the connectors over from left to right and it seems to be the right hand side injector??

Can any one shed any light on the problem?

Cheers
Andy
