So before I start, I’d like to say that I have searched the internet including here about my issue and didn’t come up with anything that sounds like what I am dealing with. I took my truck in to get normal maintenance, oil change, tire rotation, etc., and the tech (Firestone) came out to me and told me that I had an oil leak from my drain bolt and my passenger turbo. He didn’t know much about it since firestone is a tire place and not a repair shop. So my questions are, has anyone else had a leaking turbo? Will this effect my gas mileage, if so, what is everyone else getting as far as gas mileage? I’m getting roughly 13.5-14 MPG. Is this an easy fix? What causes it? just basic question regarding this. I am just worried that it could be a bigger problem than what it seems. I don’t see any oil spots on my drive way, so it must not be leaking that bad. Any help would be appreciated. Thank you in advance!

The oil lubricates the shaft of the turbine inside the turbo. If there are supply issues, the turbo is operating without proper flow of lubrication = failure. If it's the drain back to the oil pan, it's probably not a big deal, but you'll lose oil over time if the leak get's bigger. Turbo replacement is about $500 per side just in parts, so if it were me, I would do everything I could to keep up with the PM regarding them. I'd get it fixed or looked at by someone who know's the system.

coolant leaks at the turbo are extremely common - my fitting on my passenger side turbo was leaking, as it leaks it drips down around the turbo housing and collects on the turbo oil feed/drain line; this makes it seem like the oil is leaking; i would just confirm its not antifreeze by touching, smelling and feeling it (the drips)

if oil, you want to get that fixed (turbos need oil) - the turbo coolant jiffy tite connections are notorious for leaking on the turbo where the o-rings in side of them get extremely hot, turn brittle and start to leak so coolant is a more common leak
