So for the second oil change in a row, my drain bucket was full of a slight pearl tinted oil. I checked oil pressure, didnt seem too terrible even though i couldnt get the sled overly hot in the shop. Cut the oil filter open, didnt see anything all that crazy in the element, a little trash in the oil that dumped out of the filter.
I wasnt totally shocked, i got the sled mid last season, no tether, tune out to lunch with too much boost for the fueling. I gave it a bunch of love, but was having a hell of a time getting my new fueling system figured, and it was running like trash the last couple rides of the season.
Anyhow, strait to the rod bearings, look alright, crank journal bearings, look ok as well. Slight wear from perhaps the contaminated oil. Cams out, look good, journals on the heads look good. Cylinders look decent, id run it as is if i didnt need to clean everything up now.
My turbo has been passing oil into the compressor/turbine, some shaft play, but nothing touching the housing at all. Assuming the turbo is putting some trash in the oil, the only other thing is the return pump. Its an Alpine mag driven MCX copy. It shows a bit of wear on the inside of the housing, and a bit where the drive pin goes through.
Is there something else im missing?
The kit is a Alpine low boost rear mount, I assume a trask kit? Upgraded scavenge pump, regulated return fuel system, Boost-it setup, etc. Im this far into the thing now, id hate to overlook a piece of the puzzle.
Thanks guys
Brian
