I think it's called the air switch valve on a 636, it's the plastic valve on top of your valve cover.

Air injection control valve on an F4I

if what you are talking about is the stock part which most people use to do the clean air mod instead of a T tube, then i cut the wire, its no longer attached to the main harness
anyway, i stripped down the engine today, found out that 2-3 disks from the clutch are broken and rod #3 had broken and had grenaded into the engine case as most you guys assumed
i didnt manage to remove the flywheel and clutch as i dont have a rotor puller and a clutch center holder
is there any way to remove those without the tools or i need to buy the tools?

what a rod cannot break if you revlimit that shit 4-5 minutes?
whats your input on those two tools to remove the flywheel and clutch ?

You're gonna fix that motor? You could probably buy a used one cheaper

the germans are crazy when it comes to engine prices ... one f4/f4i is at least 600 eur
i paid like 100 eur for the rods, crankshaft and the engine case, the case is not good but probably i will turn it into a small coffee table
the welding is 100 eur tops, so im good with 200 eur, if everything goes fine of course

so today i got the case from the welder, i hope it will hold
so then i went to the garage, cleaned the case and put in the pistons rods and shaft
and assumed that top dead center is when piston 1 and 4 are at the top of the cylinder - that was to me the only way for the rods to be straight
i tighten the the rods to 25nm as written in book
i then tried to rotate the shaft but i couldnt
could this be because of the new set of rods&pistons which might not be aligned to the cylinder?
or i did some stupid shit ...
