as the title says, buzzing/ whirring sound coming from the front of the motor, it sounds exactly like this:


after searching, it seems its some oil valve by the oil filter. Some people suggest to change the oil filter, problem is that i just did an oil change on it with good quality filter and it was making the noise prior to the oil change. It first started once in a while, then it stayed on of longer and longer and now it just buzzes all the time. Did anyone go through this? is it part of a bigger problem? if so, should i change the oil filter and PCV again? i appreciate the help.

I don't hear anything out of the ordinary.

o man, really? ill try to record it on my car as well, i guess its being masked somewhat by the fans but you can def hear a slight buzzing.

so switched out the pcv,nothing happened. no one had the same issue?

SOLVED, it was the damn oil filter. swapped out the bosch for nissan oem from Z1. still no idea why it was happening, i've had bosch in alot of cars and never had an issue. anyway, if anyone experiences this, its the oil filter

That's weird, we have run Bosch and Wix filters on our G for over 100K miles with no issues. Maybe you got a bad one??

Probably just got a bad one with a broken check valve.

very well may have been a defective one, who knows but it went away so im happy
