mate if someone is yelling out to ya fix your rings, then ur blowing some blue smoke (i.e your burning oil). however that could also be due to worn turbo seals. so just get a compression test done, and that will tell you how bad the damage (if any) is. compression tests arent expensive anyway so its worthwhile getting it done.
if it is your rings, then hopefully you have some money saved up.
all the best dude
