Thinking I may try tackling this today (if its not raining), prior to our trip up north tomorrow. I'll probably just remove the throttle valve, though. That way I don't have to worry about what I use, and all the crap I cleaned out.

Good call. Curious how your intake looks. Great time to do this before a long trip!

For sure - especially with so much freeway. I've noticed that it really hasn't been as great on the freeway as it used to be. I'm hoping this is all related.

For the last few years, the majority of tanks are 80-100% city, for what it's worth.

theres a 8 mile 10% hill on my way to work, 4000+ engine braking down the hill, 4000+ lower gear up the hill, every time

That's what I miss about not driving to North Carolina anymore (in-laws moved to Atlanta) is driving on I-77/I-64 through the Appalachians.

Full decel-fuel-cut, engine braking down that grade while going 70 was a blast!

I wonder if you can just block off the egr valve?

If you are deleted, you absolutely can.

Sounds like Seafoam.

**** takes all sorts of carbon buildup off, and makes your vehicle appear that it is on fire when you go for a "spirited" drive after.

Should still work for a diesel, I'd think, as you suck it in through a vacuum hose. But yours may very well have been past what could have been removed even by Seafoam.

89 in-lb

 

[MP81]

for both, egr and throttle valve?

Yup! The throttle valve is a straight torque, the EGR had another step in there, like 51 in-lb then 89 in-lb. Given how small the torque is, that's kind of surprising they even bother.

 

[MP81]

So that you neither under torque OR over torque.

Sure, but when it comes to that low of torque, it is rare to see. Especially when you look at other parts with the same torque spec not needing it.

But it's likely to make sure it settles down on the seal evenly.
