ECAS has them.  £52.95 plus carriage for a set of 10. (Could do your repair and then hawk the rest on here for, say, £40?) Never done it myself, so I can't offer any advice based on experience. However, there are plenty of videos on YouTube to help. eg Doesn't look too onerous. Hope this helps! |

Looks straight forward but I think I would prefer to remove the head - do not want any debris to remain in there.....

Be aware. The insert thread (tap) is 16 x 1.50 mm The heli coil thread (tap) is 16 x 1.25 mm but internal are the same 14 x 1.25 mm. This guy did all the wrong things. No grease, hit the edge of one valve, hit the piston and left all metal chips inside. Complete fuck up Attachment: 31.JPG Attachment: 30.JPG |
