Glittery Oil
My last two oil changes have shown some "glitter" in the oil. The first time I assumed ( hoped) it was just dirt or something in the catch pan. Last oil change I cleaned the pan out thoroughly before draining the engine. Still had glitter. I checked with a magnet and it seems that the glitter is not magnetic, although it was hard to tell for sure given the oil sort of coated the magnet.
The engine has 110k, oil changed every 5k miles with synthetic. Boosted at 12# and not tracked and not really beaten on much. Uses no oil or coolant, plugs are uniformly clean and tan and engine runs well. Tune is pretty conservative but a few degrees of timing hotter than the FM base tune on the Hydra. Data logs show no knocking, so all should be good. Except there's glitter in the oil.
Any guesses as as to what is going on? Wouldn't any piston damage to detonation go out the tailpipe? Beating down the valves? VVT head is stock, but I ususally shift before 7k rpm. No valve train noise is evident.
Suggestions?

or just kep driving it till something happens. If you send the oil off and it comes back bad, you are possibly looking at a rebuild. If you drive it and it actually begins to knock, then you know it was a problem and needs to be rebuilt. Its not like you can remedy the situation with magic aditives after a Blackstone analysis. if its dying, its dying.

Plan for a while has been to build a new engine to swap in. I probably need to push that forward. A little bit. Maybe turn the boost down a little too.

A little gun shy on the build now after reading that you have to calculate bolt stretch, not torque stuff. My last engine build was a small block Chevy about 45 years ago. Maybe a new turbo engine needs a finer touch than I've got. Anyone have a recommendation for a good builder in Northeast or Central Florida?

What fasteners require measuring bolt stretch? I assembled a bp this winter and didn't see anything that didn't list an actual torque number.
These are simple engines. If you have any prior engine assembly experience then you're more than qualified to do it yourself IMO.

You're right, measuring stretch would be best, but If that is what is keeping OP from assembling himself then I feel he should be aware that isn't the only option.

Mazworx in Orlando is highly competent as an engine builder. The owner is a friend. He also CNC machines SR20 and 2JZ engine blocks out of billet aluminum, lol. He built my engine and Tony Montana's engine.
He built an SR20 motor that makes over 1400whp for a customer, FWIW.
