Hi Rob,
Been around Limbachs & more particularly VW’s for more years than I
like to remember now & although I know of clip failures (rare) I have never
come across a bent valve as a result, so I doubt that is the cause of your
distress.
You can dismount the valve springs without removing the head:-you need to
pressurise the cylinder using an adapter made from an old spark plug bottom end
welded to an air line fitting. Once you have the rocker shaft off it will not
matter where the cam is: the cylinder will pressurise, but make sure piston is
at Bottom dead centre first or prop could whip around on you. Once the valve
springs are off I always secure the valve(s) by using a bit of lockwire about
6” or so, secured in the collet grooves to stop the valve falling into the
cylinder and also so that I can pull the valve back up. Once this is done you
can decompress the cylinder and ease the valve down the guide. Any stem damage
will be obvious.
Hope this helps
Regards
JGV

G'day All,
After our L2000 rocker shaft clip popped off things haven't gone so well.
I replaced all the clips on both side rockers but it is now running quite badly
with a noticeable chatter at higher RPM's and a loss of power.
I am suspecting that the sideways movement of the rocker after the clip came
off may have bent the valve and it is sticking. It is not a bent pushrod.
Has anyone had similar experiences?
Rob
