Hi guys,
I know this topic has come up before, but I've never found a thread with any kind of closure, or with my exact circumstances, so please excuse me if this has been discussed before.
I noticed a ticking coming from behind my engine a few weeks ago. It's not overly loud, and I can only hear it with the bonnet open, but it was annoying me nonetheless, so I did some research and read a lot of threads and came across people saying it could be the fuel pressure regulators. I felt them both to see if they pulsed in time with the engine tick, and it felt like the passenger one did exactly that, so I ordered one from Zmanalex (excellent as always), and with some trepidation, replaced it myself.
To my dismay, this didn't get rid of the ticking. I have uploaded a video of the sound as it is now, with the passenger fuel pressure regulator replaced:
Does anyone have any ideas? Should I replace the driver's side (primary?) fuel pressure regulator? Is it noisy injectors? Will this ticking, whatever it is, cause any damage or be indicative of previous damage?
I should add that my oil level is fine, and the oil was replaced only a few thousand miles ago.
Any help would be greatly appreciated
Cheers
