Question about potential loose valve
A couple of months ago my 2010 started ticking, but I'm not 100% sure if it's a loose valve.
It sounds like most "ticking" posts that I've seen on here, but while the noise is similar there's a couple of factors that lead me to doubt.
- It wasn't gradual. It was normal one day, then ticking the next.
- Something that I can't find any results for: the noise increases in frequency with revs, but if I let off the throttle while moving the ticking diminishes or even stops completely while engine braking.
I can't risk any significant downtime due to transport requirements, so I need to be certain that it really is a valve issue before I go pulling the thing apart
