Well after having a closer look (listen) to the engine I realised the ticking sound is not my new tappets after all... it's actually the injectors! They seem to get louder as the engine heats up as well, have other people witnessed this phenomenon? This is on a el futura.
Now the question is, do loud injectors imply sick injectors? My idle is a little rough and Im not sure if it is due to the new cam (although it's a very mild cam) or now maybe the injectors?
