Tapping!?
 

Any ideas!?


Thanks

could be the ssv ticking sound

I was thinking ssv but I don't know how to check to maybe eliminate that!?

SSV actuator arm. Put your finger on it and it will go away. No real fix for it other than replacing it. Mine came and went, I just dealt with it until I pulled the engine.

Yea I found the arm and whilst the noise was occurring I pushed the arm in, the noise stayed but someone also mentioned to put my finger on it but I didn't understand that. My engine has just been rebuilt 450miles ago!

I also have the same exact noise. Taking her to mazda to have them take look tomorrow. Also seems like there's a lack of power, not sure if it's related. An overall lack of power, not falling off or anything. Doesn't pull like she should

If the issue is indeed with the SSV actuator and impacting its operation, it would cause a performance hit. Off the top of my head I believe the SSV gets engaged at 4000rpm

Hi Luke, It is indeed the SSV - I demoed my "Diesel" sounds last time I was around yours. The shaft can be seen in the small gap on the left & you may just be able to squeeze a hand in there and put a finger on the shaft... The noise stops.

It engages at 3750RPM - and that should also be observable with somebody increasing revs... The noise typically disappears when actuated... (Or is completely drowned out with other sounds!).

I doubt the vacuum actuators are replaced as part of the rebuild process, unless obviously broken.
