I am aware that boxers tend to have a bit more valve train noise than other engines. Nonetheless, I would say in the last week or so, I have noticed a definite ticking sound between 2-3000 RPM. It gets better when things warm up, but it is still there. I am pretty sure it is tappet noise--the only question is---Is it excessive and signs of a problem to come?--or nothing to worry about. This is an 05 STi with 11K on the clock--not babied, but not abused either (occasional "spirited driving")--certainly nothing that should cause any problems.
If it was a VW 16v, I would say an oil channel to the hydaulic lifters is clogged with slug or oil pressure is otherwise low, causing gap and hence ticking (I had this problem on a GTi). I cannot imagine anything like that with a 11K engine, but I suppose it is possible.
I might be worried for nothing, but I cannot shake the feeling that the noise is a little louder than normal--a definite tick, tick tick, that goes away at very low speed, but is there once i hit 2000 rpm. At high revs. it is hard to tell because of other engine noise. I did just get an oil change a couple of weeks ago....
Any thoughts?
