Sticky Lifter ???'
Hi
Following on from my last post I have had a couple of people say that "Could the noise be a sticky lifter" ???
Is this something that can be the problem and do they suffer from this problem?
Its a ticking noise coming from the right hand side that does not go away
definatly not coming from the centre of the engine and when I last drove it it sounds like a playing card on a pushbike wheel spoke like we done as kids
Drives ok (only drove it home from were it started doing it) but is slightly down on power
Your thoughts please
Ian

As above and like my last comment. If you're talking about a classic and when you say right you mean near side have you made sure your coil pack to ht leads aren't arching?

Could be a shim going out of tolerance, had a shim fail on mine that caused the same kind of noise to begin with

The sound is defiantly not coming from the centre of the engine so don't think its the ends and still drives ok and the noise doesn't change under load if any of that helps.
Only on the right hand side too as in the vid

that does sound a bit nasty. take the cam belt cover off on that side and check to see if the belt is flapping around.

Get a stethoscope and listen round the engine, its quite hard to tell from the video, hopefully it isnt but that sounds like big end knock to me.

I don't think that's a big end knock, big ends don't knock at idle unless they are totally shot. That sounds similar to when a shim went missing on my mates version 4 type R, we found it in the sump and replaced it and the noise vanished. I don't know which types of shims your engine uses, his were under bucket and it somehow slipped out creating a massive clearance.

the shim is what is used to adjust the valve clearances because Impreza's don't use hydraulic lifters. The shim will either be on top of the bucket between the bucket and cam or underneath the bucket between the bucket and valve depending on which type is fitted to your car. Which model Impreza do you have?
