If its is a good filter, you should see some dirt because it should be filtering. If none, then maybe it has gone bypass already.

Or your engine is really clean.

Small gasoline engine (1.6L) with two big filters (Baldwin B2). Dirt could have been too much dispersed in the filter elements for me to notice anything. Besides, 7000kms+ pa lang.

I've also just opened the valve cover to check the valve clearances (although I cannot do adjustments, I'm monitoring the wear on the cam lobes because of stiffer valve springs). Valve train is clean --- like the way it was when it was after chemical bath last general overhaul in 2011.

Engine is really clean.
