Oil change, transmission fluid/spin-on filter change, rotated tires
Held off on changing the air filter, but when I found that there was a stored turbo boost code I changed it. Looks like the code is still present/occurring under likely max boost conditions (2k RPM, heavy load). I'm suspicious of a minor exhaust manifold-to-up-pipe leak since I saw a little bit of soot at that joint - the up-pipe face looked pretty corroded when I changed the driver's side exhaust manifold. Guess I'll have to try to find an up pipe. Hopefully the bolts come out of the turbo exit - I broke all 3 in the manifold I was changing.

Oh yeah - should probably do front pads and lube calipers - driver's side looked like it was more worn on the inner pad. Rear pads are low-ish and it's probably time. Rear calipers look pretty crusty, so it's probably time for another set of those (put these on in 2012... nothing lasts 
)

Intermittent SES light still coming one due to low boost. Looks like I'll need to take on the manifold-to-turbo-up-pipe joint. I wonder if high temp RTV with a new gasket could fix it. I doubt the up-pipe-to-turbo bolts will come out without breaking them off in the turbo housing, at least not without cab or transmission removal.
I guess I'll order a couple gaskets and attempt high temp RTV. I can't think of what would fill better/more resilient to exhaust temps.

I could also put in double gaskets, but I'm not sure if that would be better or worse.

Trying to get ready for brake pads all around and likely seized bleeders/sticky pistons on the calipers.
Since the rears are crusty, I'm thinking the new AC Delco premium set for $196 seems like a good move:

The fronts I may or may not have to replace, but they don't seem to have a similar premium set on RockAuto.
NAPA remans are $84 ea: https://www.napaonline.com/en/p/ADC2453XB
or
$70/$82 for new AC Delco Professional Gold, but I don't think they're coated (but might be galvanized?)?

I could also try to make NAPA warranty the rear calipers, but that feels like cheaping out if I can buy true new parts for "only" $196.

And NAPA is doing 20% off through Monday. Or I could try changing the pads and see if the fronts move freely and bleeders are serviceable. But it does bring the fronts down to $67 each so it seems like that's probably the way to go? IDK. I probably will try to do this mid next-week. Returns at NAPA if I don't need them are easier than any RockAuto options.
