Having learned how to change the rocker cover gasket on this and my 5 series I took it upon myself to have a go at the Vanos Repair procedure after looking at both the Beisan method, X8R method and some YouTube videos.
The procedures were spot on....my only personal advice is not only to have the right tools but also make sure they are good quality. The cheap fan holding tool from Amazon snapped while removing the fan so I had to wait for another from Laser.
Also...take your time. Check, check and recheck everything. The number of times I put the washers and bearings in and out of the piston in the right order I could probably do it blind folded.
I didn’t know I needed to do this until I drove the car. At first on starting it up it misfired on all cylinders!! I have a code reader. I stopped the engine and restarted with no problems.
I literally shot off down the road....the lower end power was instant hitting 3000rpm very quickly like something had been released and then pushing on further to the redline.
On the motorway the response was similar, dropping down a gear and flooring it, it couldn’t get to the redline quick enough and I found myself doing (ahem) 70 very quickly.
It is a long job to the inexperienced but there are a lot of guides out there....just be prepared to take your time...it’s worth it.
I’ll give it a week and see how it fairs but it seems the car has been completely transformed.
