Should the 6, 6 mm bolts have flat washers? Mine do, but in looking at the how-to's again, I don't see any washers.
Yikes, unfiltered air.
33k, a little worse than pictures in post #16 (about 40% restriction on EGR valve, 30% on intake)How dirty was the intake and how many miles on it since the last cleaning? Have all of those miles been on ULSD?
How tight did you have them when reinstalling? Did you use a hex wrench/bit or just german spec(goot'n'tite)?Too late, installed with washers. I'm 95% sure that's right.
Did an impromptu intake cleaning today, my THIRD in this car, after all but one of the intake manifold bolts fell out sometime over the last 33,000 miles. I was trying to figure out why they fell out so posted.
Symptoms of leaking intake manifold were a very odd noise at >1/2 "throttle;" got lucky and in checking things over grabbed the intake manifold and found it loose. Wasn't until I came home today I realized that its was hanging by 1 bolt. Also rough shut downs as anti-shutter is thwarted by air flow around the intake.
I honestly do not remember, but definitely good n' tight with a 6'' 3/8'' drive ratchet, it would be such a bear to try and use my torque wrench in those confines. It does appears I made the mistake of using a little anti-seize.How tight did you have them when reinstalling? Did you use a hex wrench/bit or just german spec(goot'n'tite)?
Hmmm, I see. A few people said to put nothing on them, as they go in dry and by themselves. I don't think a small droplet of locktite would be a bad thing. I don't think I could get my torque wrench in there either to get the factory spec torque on those.I honestly do not remember, but definitely good n' tight with a 6'' 3/8'' drive ratchet, it would be such a bear to try and use my torque wrench in those confines.

I'm thinking that if maybe just one came loose (could have even missed torquing one as I put them in by hand first), that could start it all with the increased vibe for the other five. I've also had a bad DMF until recently so I've had no shortage of vibes and, at idle, what I think may have been harmonic resonance. Add all of that to the oil leak from the VC, and I have plenty of explanations.
I know this isn't recommended, but this was such a pain to have to do around the holidays that I used a dab of blue locktite this time.
All ULSD. Doesn't help my car.
I was hopeful as well, that is why I went back to the stock EGR adaptation value after intro of ULSD; I was trying to do something good for the air but this rate of build-up is unacceptable to me and I'll be adapting my EGR again using VCDS.This is disappointing. Multiple experts should be coming in this thread to tell you you're wrong.
Oh yes you can get a torque wrench on them -- EXCEPT ONE.Hmmm, I see. A few people said to put nothing on them, as they go in dry and by themselves.

I'm certainly going to try to get a torque wrench in there if I can.Oh yes you can get a torque wrench on them -- EXCEPT ONE.
You think mine ran a bit on the other stuff prior to the switch?In the US all road fuel has been ULSD since '07 I believe -- federal law. Non-ULSD will damage or destroy emissions equipment on newer vehicles just like leaded gas does to catalytic converters.
I guess the only to find out for me is to get all the gunk out, and drive it a few more years.Mine definitely did for a number of years, and clogged on it too. After hearing all the folks saying that ULSD was supposed to stop the clogging I was quite-surprised to find that while it appears to have slowed it down some it certainly didn't stop it!
