All that's left of piston 2 bent exhaust valves so it looks like I was lucky Comments Permalink Submitted by p.mole1 on 14th Aug 2019 - 19:13 More holes Permalink Submitted by JohnJo on 15th Aug 2019 - 07:50 Really sorry to see that this has happened. Permalink Submitted by p.mole1 on 16th Aug 2019 - 20:11 Thanks I think it's just bad luck however it's nothing I can't fix and I like a challenge. Luckily my head seems to have survived as that was the most expensive part of the engine! Bearing all seem good so I don't think it's a lubrication issue I should have the all the parts together in the next few weeks for the rebuild. I may manage a track day in September Permalink Submitted by p.mole1 on 22nd Aug 2019 - 13:52 Head is now apart Permalink Submitted by p.mole1 on 22nd Aug 2019 - 14:19 After speaking to the K Series guru Dave it looks like it was a spun bearing. God only knows why they machined the second groove Permalink Submitted by p.mole1 on 23rd Aug 2019 - 20:53 I've got a new bottom end!
