I've had this ticking in my head since I bought the car (I bought it used with 60K). At first I thought it might have to do with the release bearing, but have since replaced the clutch and all workings and it's still there. I've checked the manifolds and have not spotted a leak, although I'm not entirely ruling out a leak in the manifold. Its hard to tell cause the exhaust is so loud to begin with.
Anyways, I don't hear the ticking until I get the RPMs above 2600, then its a very rapid and light tick that possibly goes away after 3600 RPM (again really hard to tell because the exhaust is so loud). I've had the engine compression tested and it's not a con rod bearing (too quiet and not persistent enough to be shot bearing) so I'm left with a valve out of adjustment?
I was just wondering if anyone has had a similar problem, if anyone has any other ideas and if anyone else has ever had their valves adjusted? From what I've read it's something to consider, and I was going to call Subaru and see what they say for price and time frame of a valve adjust, but I trust you guys waaaaaay more than Subaru Calgary.
