Hello @Stevieshutts ,
I think I followed what you described correctly, if not please tell me, if I did follow correctly, I think that you will still have issues if you did not fix the leaks on the two larger tubes.

Please see my video.

Hi Johnny

Great video thank you. I wish I had seen it when I started thinking about this problem a few weeks ago - answers lots of questions on where all the pipes go.

With regard to the T with the rubber elbow going up to a check valve, which on your car is at the passenger side - on my car it is at the other side and was the fiddly bit. I disconnected the rubber elbow feom the T and connected the elbow to the new pipework I installed, so it does still have a connection to the vac pump. It's not easy to see what I did , but if you look at the first of my pictures above, point 1 shows a piece of the new pipe running through a hole where the heat shield bolts to the body, and into where the rubber elbow is located.

You are right that the larger vacuum hoses may cause me a problem in the future. The top end of the large hoses were split, and I fixed those by cutting the split sections off and fitting rubber hoses - an easy job in the top of the engine room. As for the lower ends of the larger hoses, they are still untouched, but they didn't leak when I smoke tested - fingers crossed that they stay that way.

Running a new pipe under the crossmember and bypassing the lower bulkhead pipe is not a full solution to the vacuum pipe challenge, but from what I have seen and read, it fixes the most common problem, which is the smaller diameter hose running right across the car behind the steering rack. It definitely made a huge difference to the way my car runs and it was definitely much easier than removing the steering rack. Plus of course, I can now access more of the system than I could before.

I have to say, this forum is brilliant.

 

Update, still going strong and about to service the car and put it away for winter. I’m Glad to see other’s tackle this on their Bentley’s! Great job. I would still like to do a video of the repair but just haven’t found the time or another car to do it on .
