This is probably something Matt Colie would have a lot of experience with, being "a refugee from dyno land".
How much grit and grime would be considered normal in the bottom of an oil filter? Any? None?
Does the pressurized oil come in the 3/4" inlet and flow out the little holes, or vice versa? In other words, is the dirt on the inside of the paper pleats or the outside?
My paper looks clean on both sides, but I do have some grit, most of it much finer than sand, on the bottom of the filter housing. I cut it apart with tin snips, so no abrasive disc was used.
The oil has been in there a while, but only has about 1500 miles on it, if that. It has been changed twice during my tenure, once when I got it home, and again after changing the timing gear and intake manifold. It is synthetic. I've heard that changing to synthetic from dino oil can result in dirt being dislodged from internals, but I don't have any information on what oil the PO used in it.
