When I changed the gear oil in transmission it had lots of SWARF......unknown when last time it was changed but it had enough in it to hold a magnet through catch container no filings just tons of powder hoping it just wear and tear and very old oil

As for engine oil Here is main source of oil leak, the ultimate source I am not sure. It is manageable for now I believe in the “live with it” category since haven’t had to add oil yet. Just did an oil change and sent it in the black stone labs just to get it analyzed. Should i UV test to see if maybe just leak down from valve cover area etc? Not sure if I want to get into rear seal territory yet if not having to add oil
