No I do not have it. I can tell you that the single zip tie around the whole rubber connector will do more to create vacuum leaks than to prevent.
EDIT, text added: Zip ties can be used, but work much better if you slice out enough rubber between the pipe holes to use 2 zip-ties, 1 around each pipe. If you do that, it means you will connect/disconnect the pipe at the other end during plenum pulls, where the small spring clamp is.

I haven't personally done what I'm about to suggest, but have sure thought about it while having difficulty with that pipe & the rubber connector. Why not cut off a short section of the plastic pipe & glue it into the connector? Then get a section of vacuum hose long enough to eliminate the looped section of plastic pipe so it's not so hard to install.

Sounds like a plan, since I won't have it back together for awhile. Good suggestion.
Yun had also mentioned about gluing that end into the connector.

That connector also feels very soft, don't know if it is supposed to be that way, or is that from the heat generated in that location???

You need my billet EGR plate to replace that nasty black piece you have there......

Send me a pic and info whenever you can.....

Looking over Marc's papers on the TB, apparently the info mentioned in his
Throttle Body Service page points more to a vacuum leak for me, rather than the TB itself. There have also been other members who have stated the same thing.
And also learned something else on this read, and that is, that Dag is not used on the primary throttle blade.


Just for clarification, the sentence below was JMO, was not read anywhere...
Of course the leak can be so minor and only occur when the engine goes in Closed Loop.
I think a gasket change is in order and a complete check of every line.
I also need to find a 1/4" drive T-40 or a thinner 3/8" drive T-40 socket when torqueing down the plenum bolts. There are 2 bolts, 1 on each side of the plenum between the runners, that is very tight to get in there. I had to use a 6mm Allen key and a spark plug socket to go over the Allen key for leverage with a short extension and the 3/8" ratchet to break 1 of those bolts loose.
So if anyone knows where I can get a thin walled T-40, it would be appreciated.

Found an extended Torx set in 3/8" drive that will work perfect....

This does not happen. A vacuum leak is a vacuum leak. It doesn't care about open or closed loop. There's nothing that happens in closed loop that would create a vacuum leak if there wasn't one there already.

Remarkably clean coolant passage. I assume you've installed the Carter bling on the TB? How did it look under the old TB cover?

How did yours turn out?
