You can see into the ports ok!

You guys saying it can be done from the top must have some super powers.
Took me 5 Hrs to get the manifold off, it wasn’t even that badly sooted up.
I think VW may have been in here while it was under warranty, there’s a few odd fasteners and some clips are newer than others.
Any idea how I go about cleaning the crud out of the inlet runners without filling the engine with crap?

Wow there’s a lot more to your engine bay than mine did u get sorted?
I got the manifold off, it took some doing!
I’ll bathe it in brake fluid to clean if tomorrow, while it’s bathing, I’ll make a start on cleaning up the cylinder head, at least mating face, ideally I’d like to clean the inlet ports, but I’m a little dubious about bits falling into the engine, some of it can be quite hard.
The suspected hole in the manifold turned out to be a split front EGR pipe, rite where it enters the inlet manifold, so that will need replacing, both bolts on the other end of the front pipe sheared off, so it NEEDS to come out now, just not sure if it will go back in or not yet.

Curious why you need to remove it?
You need VIP Membership. Just follow the process for a small annual fee.
Turn the engine by hand until both valves are closed on each port, they should hold solvent and definitely shouldn’t let carbon pass.
Worth every penny
I don’t have the part numbers but somebody who does is going to ask which bolt?
Are they all the same length. If so remove one, measure the diameter and length. You don't need special VW bolts, they probably have a flanged head if being used on plastic.
M (diameter) x L (length).
Indeed, they are of the same longitude. They have a 13mm hexagonal head, with 10-point internal end used usually by VW. But I don't remenber the length. And I have the van assembled, using every day, and I want to buy the screws before dismantling it again. Thank you in any case.
You don’t need to dismantle, just remove the screw with the easiest access.
Then if no solution here give VW Parts Dept a call, they certainly know what it is.
Unless it’s a common bolt it probably won’t have a part number as they are in the new manifold when you buy it as a complete unit. I dropped one and couldn’t find it anywhere but luckily was replacing the manifold. Then sometime later I removed the water pump that’s situated behind the radiator a low and behold it was laid on the top by the bracket!
I guarantee you will find your bolt ten mins after a replacement is fitted
Good luck

I’ve took mine off this weekend. I’m doing the turbo, EGR, and a new charge cooler and had the front off already, so I thought while it was apart I might as well check the inlet while it was easy to access. You don’t need to take the fuel pump off. I made a short extension bar with a nut welded on it and a spanner to get the bolt out. This was the before with 176000 miles presuming it’s not been off before
And after I’d cleaned it all up. I turned the engine to shut the valves, then used a variety of picks to pull the mess off, and got my fingers in there with some scotchbrite to clean of what was left, interspersed with lots of vacuuming the port out, and blowing it with an airline to make sure everything was cleared out. It’s not perfect, but it’s a damn site cleaner than it was before.
The inlet manifold was in a right state and after an initial clean I found it was cracked (or I’ve broke it while cleaning) where the swirl flaps mount, so I’ll be replacing it.
