Okay, some of you may recall that we have a P0306. We thought this was caused by a smoked harness, but we removed quite a bit of the...stuff...that was on the harness running over the EGR and don't see any damage. We've had a nagging P0401 for awhile, so the intake manifold is coming off for cleaning, and because at this point, I refuse to let it win. We took the advice of forum members and removed the four bolts and two nuts holding the damn thing on, as well as the bracket and all other "obvious" connections...and something is still holding it on. We used a normal socket and approximately one billion feet of extensions. I'm considering just pulling the engine and transmission to do this! Please let us know if we're missing something! We're absolutely intending to do a (very) lengthy writeup for the FAQ once we get it out.
Pics:
Do these bolts also have to come out? And if so, any trick to getting the socket on them? You'd need very small hands to get in there.
And there's one other one that seems to be slightly rounded, or perhaps of a different size, does it also need to come out? If so, does it look sufficiently rounded as to require a bolt-out?
Here's a depiction of where this bolt is from above:
Finally, what would the proper tool for removing the giant EGR nut be? Should I hit it with some liquid wrench then try to break it free with a wrench? Most of my wrenches seem too big to turn it easily.
We got impatient and pulled some of the crud off the harness. No idea what it is, but I think it probably causes cancer if you so much as think about it. Bonus before/after pics of the harness to be re-wrapped in heat tape:
Before:
Seriously, nice job Toyota. There? Of all the places, you picked THERE? I mean, look at it. That's something out of a horror film. You could have dreams that such a thing was chasing you.
After, much prettier:
