not yet, dont even have a dipstick in it yet :eeks: still in the package, almost forgot about it. its only got about 30-40 minutes of actual runtime since i dont want to piss off the neighbors too much (and the head "hoa" people live right next door).
when i first noticed it, it was after warmup. its started closer and closer to startup ever since, and yesterday it was obnoxious as soon as it lit. oil pressure is still awesome though, which makes me think its valvetrain more than bottom end. or at least, i hope.
this is uncharted territory for me, never had a solid roller before, so dont know what that sounds like first hand (though this noise is defintly only coming from just one cylinder). also never had rod knock or piston slap, so again dont rightly know what those sound like.
