I have a strange feeling of déjà vu...
Checked the valves, they appear to be untouched and are in spec same for the oil pump as well. Took apart the pump, removed the gears and I couldn't find a trace of anything. Cleaned everything and used an air compressor to get rid of any possible remaining contaminants.
For fun I did rip apart my oil filters, needless to say there was plenty of crap inside them. So waiting on rings and bearings now. Be back on the road very soon I hope.
