Hi all,

WRX STi Spec D 07/07 27k miles.

When the car is stationary, I can hear a ticking noise from the passenger side of the engine, from cold / hot.

Is this considered to be normal? Injectors working?....or a chocolate tappet / cam?

It seems to drive fine, with no problems, but why do I hear this one side, and not the other? Secondary air pump perhaps? I know that this sits between the TMIC and battery.

Could be a few things but wouldn't worry all that much. Have you changed oil recently?? Most Imprezas have some sort of noise. Just turn the radio up

Hawkeye D

Oil changed only 2k miles ago, level always checked and a small top up every few weeks I guess - just a slug is enough.

Lol yes I would turn the radio up if the speakers weren't so crap!

I'd keep an ear on that, it could be a broken piston ring land, common on 2.5's.
Other symptoms of that include smoking more than usual, and eventually, lumpy idle.

Thank you, yes I am keeping an eye / ear on it.

U sure its the passenger side? Does it get louder the more you rev?

Hawkeye D

Yes, deffo the passenger side, but not sure about when I rev it, you can't hear the noise inside the car, it's quite slight.

I'll get a mate to rev it and I'll have a listen by the NSF wheel arch.

That way I can listen down lower than if under the bonnet if you see what I mean. I can't see any oil leaks or anything.

The drivers side bank is silent.
