    It's a timing check tool , it doesn't have any association with the vanos. I don't understand the vanos clearance sentence? TIS does not mention vanos clearance. Could you explain?

    The check tool just has a little more leeway and not as rigid as the timing tool. Just allows for the tolerance of .5mm ( or whatever it is) lift of the timing tool on the head.

    The s54 timing tool has a stepped base while the s50 has a flat base like your pic. Maybe they both work equally but different part numbers and different applications to two different engines.

    Interested in this vanos clearance. Can you explain that a little more?

    I can only assume your referring to how much the splined shaft protrudes from the hub? If you install the vanos with the shafts already assembled onto the vanos unit ( like TIS advises) then you will always get this step correct. Is this what you are talking about?

    I'm with you Schooner. I put mine together as TIS explained and never had any issues.

    I did use the s50 timing bridge though which tbh worked just fine.

    probably a bit late now but I’d go for head off relap all valves, new valve seals, pop in some new piston rings, “ok possibly some kind of hone “on cylinders,, easily dose while you have engine on stand. Bring that 119k motor back to life :thumbsup: ...definitely check the oil pump chain tensioner this will probably be worn to the point of having little pits/ holes, that what I’ve found on 100 k motor,
