tapping noise at idle

Z_ealot · 11-05-2017, 09:09 AM

Also wanted to add that I've done a little digging around the G37 forums and have seen quite a few of them suggest servicing the oil galley gaskets as it seems on the earlier vq37's there is an issue with the gaskets that made oil pressure drop low enough to set off this condition. going to be swapping out my water pump this next weekend anyways so i'll try it out and update you guys if that resolves the tapping issue.

Yeah that does not sound good. I can hear the tapping noise on mine but it’s probably 60-70% quieter than that.

I’ve seen a few other videos on youtube floating around that have the exact same noise, but neither the poster of the videos or any of the people responding to the video seem to ever say whether they solved the issue or not

Does the noise go away when you put the car in gear? Sometimes my car makes a similar noise when I get home (I use a carport and frequently drive with windows open, so get a lot of engine noise bounce) but it seems transmission related as it goes away when I engage the transmission. In my case I think it is a matter of the harmonics of a low rpm idle from a warm engine and the characteristics of the transmission/clutch elements.

Tapping seems to be related to oil pressure in my case as when i rev the engine there is no tapping, but as soon as it settles back down to idle where oil pressure is lower when things are warmed up it starts tapping.

You need to install a oil pressure gauge. If you get one. Make sure it reads to 150.psi.

Will look into it, right now just concerned with switching out the oil gallery gaskets....still cant believe nissan went with paper for the original design on those lol
