SR20 Tapping..

[paulfluke]

Hi

Prob not the easier thing to tell here so my first question is is there anybody around the Donegal Town area that knows their SR20's that could have a look?

Problem is this - VVT Sr20

Hearing pretty loud tapping noise coming from the cm cover area. Noticeable on Idle but goes away with throttle. It also seems to be running rich if thats related.

Possible causes I've google from people with same symptoms

Injector tick - seems too loud though.
VVT actuator - ??
Rocker arms - ??

Anyone any ideas ?
