Didn’t have a perfect length for alternator only, so I’ve got everything but PS spinning with a 39.0” belt, and have a 38.8” with me. Tensioner makes full contact on the 39 but it’s about at the end of travel even though the belt was a bear to get on. Probably says more about the lack of a proper serp tensioner wrench than anything else.

Hopefully if it was good for the 40 miles back to the cabin it’ll be good for the 700 to home!

Home safe, uneventfully. No further hiccoughs.

Need to check the rest of the fleet for good spares/ pending failures now.

$100 pit stop in Pittsburgh. Not great but much gooder

Lots quicker to slap these on than the rear fender body work. Adds Motivation to do that rear arch though. It’s extra ugly after scraping and rust kutter-ing

On the way to F&F for humble pie this has decided to sometimes not want to make much boost. Wonder if N75 is acting up. It’s not limp mode because it’ll still smoke like a tire fire, not limiting fuel at all.

But sometimes it’ll boost like it should. I should take advantage of one of those when it boosts like I should and force over boost limp mode. If it’s mostly going to make 10psi it drives. 300% better in limp mode when fuel is limited.

First couple of hills on the way out from the campground were pretty terrible. Then I finally got it able to make some boost and got it into limp mode and it has been a fantastic drive home ever since. Just coming into town of Canandaigua right now.

Have noted the white smoke haze at idle also turns into a ton of white smoke after idling for a while and leaving. Idling through a fuel stop to keep it in limp mode. Showed this to be pretty significant. Guessing that would be valve seals? That sounds challenging in an overhead cam situation .

Swapped N12 and N75. Worse if anything

Need to go under and check actuator on turbo next.

Turbo actuator is fine
It’s a vacuum leak. New in box n75 don’t fix it either. Found when jumping Sarah’s car yesterday that I can hear the leak at idle, and there is a different noise when actuation isn’t working from when it is like when the leak sucks shut.

Got new lines on steering yesterday. Still some leak. Hoping I can put another eighth of a turn on the AN and be good. Machining has a lot of galling, I’ll be annoyed if it’s an o ring leak.

Love that exhaust hanger too. Crunchy

power steering line was a quick tighten on one connection and seems good. it was a leaker on first drive after the above repair.

Replaced a bunch of vacuum lines last night. many were hard and/or split at the connection nipples. was in and out of limp mode during testing, thought there was a chance it was good before I called it a night but it was just straight up in limp mode on the way to work today.

I'd put a vac gauge T'd into the line to the turbo actuator (which I confirmed continues to move) and it seems to get and lose vac as boost demand changes, but it usually still isn't making full boost. I haven't logged with the computer but I think it's getting exactly the boost that's called for now. Something else must be wrong or I missed a connection somewhere.

I'm also getting a bunch of oil into the intake while idling, huge blue puff leaving any stop light. gross. This was supposed to be a low mile and name brand turbo so that'll be frustrating if its seal is the reason. It shouldn't have 100,000 on it yet. Should be closer to 60-70 if memory serves.

Egr pipe cracked. All turbo drive pressure is leaking into the engine bay. It’s always something

Hope that’ll get all turbo back but I’ll bet against that. Back to the truck for now.

Running well since a battery drain after replacing that tube. I think it learned some bad habits, it was an over boost nightmare before the reset.

2 of 3 monitors set and no codes after a round trip commute.

Maybe tomorrow night something will be inspectable.

Just read up, looks like one monitor not set should pass. I’ll probably drop this tonight for a sticker. Realized this morning that I’m driving around with yellow still on the windshield, it was up in November.

Pending code for overboost but should still be good. Will drop for sticker Monday night. “Fuel system” monitor still not set. Without evap I have no idea what that monitor could actually be looking at.

Starter seems like it’s cranking slow. I think these things are infectious?
