This video shows how to fix inlet manifold leaks WITHOUT removing the manifold using nothing more than the addition of 10 x M12 form 'A' washers.

https://amzn.to/31TB4hTI did this repair on my BMW 840ci with the M62 engine in 2014 - adaptations had reached their limit and I was getting misfires at idle and poor low-rev performance. I had removed the inlet manifold on my old E32 V8 in the past and knew what a pain it was, the most worrying thing was that it involved bending the ancient engine looms at ungainly angles - and on old brittle wires that is asking for problems - let alone getting those blasted connectors off the injectors, the possibility of getting grit in the engine and all sorts of other hassles.
So, this time I used a simple method as described here to fix the problem - and it fixed it rather well with no problems four years later.
During recording I also found that one of the vacuum take-off point bungs had failed after five years and replaced that as shown.
