Hey all,

I'm a new subie owner. After having stored my Sti over the winter recently brought it out and did the basic maintenance break clean up/ new oil/filter ect.
I had some work done to it early fall new water pump, timing belt, tensioner pullies, spark plugs, and a few other things.
I've driven it 200km one day then the next I noticed a tic which I know subies are famous for. The day after I let it warm up, no rough idling i.e rpm is steady but noticed when going from low to high rpms the tic was there. I know it's not a knocking as I've heard those from others. I took it out ran it through all 6 gears. No lights came i.e oil temp or CEL.

Could this be a valve out of adjustment possibly?

A “tic” sound can also be an exhaust leak. My dump truck ticks because my manifold gasket is leaking. Never heard a flat 4 do this but I assume it could.

Subarus use shims to adjust valves. Unless your bucket is worn or can is flat they don’t lose adjustment like a v8 rocker can

Yeah believe it was a stuck lifter in the end. Dropped a litre of oil threw in some tranny. Ran it for 10 mins did oil change with filter which unstuck it.
