Is this cyclical sound normal?
There is this cyclical sound which I believe originates from the high pressure fuel pump, but I am not sure. Outside is about -10c at the moment and the engine is warmed up with coolant at around 70c. I can't exactly pinpoint where the sound originates but its sounds like its comming from the driver's side of the valve cover. Is this normal? :thumbsdow |
100% normal it's louder on colder days
It's the high pressure fuel pump. |
Yup mines been doing that since day1 and I've got 171,000km on it. Not 1 engine problem yet.

I'll leave this up as reference for others in the future. |
Yup that sounds like a very healthy lnf
