Whats up VA, the other day i was driving normal, not getting into it at all and i pulled up to a light and started to pull away when i noticed the engine started tapping at 2400 rpms. It will tap in any gear only when the pedal is feathered. It idles normal with no tap and at WOT no tapping either. All the power seems to be the same as usual. Car is a GSR bottom end with a b16a2 head, GSR cams, turbo. It sounds like its coming from the back near the intake manifold, just replaced the lma's today, didnt fix the problem.

Checked the valve lash?

They were all adjusted 500mi ago since the build. I'll try and get a video up tomorrow

When's the last time the oil has been changed? How many miles? I'd check the lash as Fabrik8 asked.

Also, make sure it isn't something stupid like an exhaust manifold leak.
