Right bank vacuum leak

Good day all. I fixed my left sided vacuum leak with a camera a tube and flexseal about an 18 months

ago. I couldn’t find anybody that wouldn’t pull the engine to work on.

I’ve now developed “ small vacuum leak” for a few weeks Followed by “large vacuum leak” warning lights, and I can hear the vacuum pump cycling going up hills and other times.

The Brakes are great, and no sound of vacuum pump when I applying the brakes.

I did a smoke test of the right side. The smoke emerges only from my right side turbo intake horn. No smoke under the car or other places are that I can find.

Ideas? Seems odd to me. Perhaps bad diaphragm??

Here is a Vacuum diagram. It's for my Gzt Speed which I know has located the vacuum behind the head and not on the trans. However all the systems will be the same.


I hope it comes out clear.
Frank.

All Frank's pictures are showing fine, @scrinja, you may have to refresh the page or restart your browser, others here have said that in the past, that their isp was blocking pictures somehow, I believe that they logged in from another source and had no issues then.
