If you are going that far. Now is a good time to change out the oil pump. Since you're there.

Hey op, is the noise coming from the back of the right side cylinder head? I can't view the video at work.

Seems like it, but most of them are small issues that just piled up from previous owner neglect. I’ve resolved the majority of them, it’s just little things like this and the water pump that are left to sort out. Water pump is being taken care of this weekend


P. S.

Think i may have found what was semi stalling the engine....not sure how it got there, but there was a 1/4 inch sized hole in the bank 2 air intake resonator. Patched it up and engine seems much happier now

When I first got my Z I heard a tapping coming from the rear of the right side head. I thought I had a valve train issue. It turned out to be purge control valve. That's what you may be hearing. I could hear it if I was standing on the left side of my engine bay but it was a little more quiet. You can put your finger on it and feel it pulsating for every tap.

I think if it was an oil pressure issue you would possibly have advance and retard issue for the intake cam since they are driven by oil pressure.

Hope this helps, I can only do so much over the interwebs.

That might explain the fuel odors I’ve been smelling then if it is the purge valve lol


Just to clarify though, is it the pcv valves at the front if the engine you’re talking about or the actual purge valve on the canister? Cause i replaced pcv with new oem like a month ago

Nevermind, think i know what you’re talking about....it’s that stupid valve on the back of the upper intake manifold isnt it?

Makes more sense of your constant + long term fuel trim too. Seems you found the vacuum leak. It's tough today without a smoke machine, so many sources for vacuum leaks now.

What dread mentioned is making sense too, I’ve been getting that ticking/tapping noise for quite a while now and if evap purge valve is the cause it would also contribute to the fuel trim issue as well from what information I’ve gathered

No the tapping is from the Evan purge sol duty cycle being commanded on and it normal, they can be loud. Had many Acura customers thing something was wrong with their car but it’s just the purge valve and Acura puts it right by the firewall on drivers side so of course the driver hears it. It won’t change your fuel trim because the ECM is commanding it on and knows to correct for the fuel vapor.

This may sound really obvious and I’m sure you’ve already checked but is your oil low? Low oil will cause those lifters to be loud as hell
