correction! just picked up the truck and mileage is 132K, aka still within the warranty limits so ASSUMING there's no fine print I'm missing, I should be able to get this covered under the extended warranty. First time I ever sprang for an extended warranty, maybe it was a good move.
You guys are a wealth of knowledge to this novice - thanks for sharing

I replaced mine myself a few weeks ago. 2 new standard products turbos from Rockauto and both new oil supply lines for them. Oil, oil filter, and coolant bright my total for all parts to about $1400. 5-6 hours per side since it was first time replacing one ever. Wasn't too hard of a job. You say you're 2000 miles over. How many miles are on your truck?
I've looked at the prices on RockAuto and OEM just for future reference. The OEM are only $100 more so I will likely go with OEM when the time comes.

I just used my oil life monitor.. Roughly 10,000 mile oil changes. I do lots of highway driving. The screens were between for sure when I took them out. I could still see through the screens though. They weren't all gummed up and plugged.

That should've said the "screens were brown", not between. Lol. Maybe I should go to more frequent oil changes. It couldn't hurt. I can't say I saw anything in the screens that suggested more frequent oil changes would've helped. I will say that this week the new turbos, I'm letting my truck idle for about 10 minutes after driving. That should definitely help longevity.

I used to be a common procedure to letting the turbos cool down after running them on the highway. That was before water cooled turbos were put into use. Not really necessary anymore.

Really?! That's interesting. I'm basing that statement on the fact that I drive commercially so it's common practice to let our semi trucks idle for 10 minutes or so after driving long distances. Not just to cool down the turbos down but also to keep them lubricated while the impellers is still spinning.
