Hi,

Need a bit of help with this ... I cannot for the life of me get the valve gap adjustment caps (see photos) to unscrew.  There is no room to get a socket on the caps - a 23mm spanner is too small and a 24 feels a little loose.  With either a ring spanner, a set of robo-grips or an adjustable spanner I am starting to round off the corners.  Getting heat onto it will be really tricky as it is so confined and it has an o ring inside I don't want to melt.

These compress an o ring so I don't see why they would be so dam tight.

Anyone know about this issue and/or how to deal with it?

 

Thanks

 

Anyone?
