Good to hear from you again, but bad about the chain. That usually means bent valves... (Chains usually rattle before breaking. Unfortunately belts don't, so the preventative "replace every xyz,000 kms" (or every n years) should be heeded.)
I might have to catch up on this thread - I've been slack since our exchanges whenever regarding whatever. (I haven't recovered the backups prior to my last PC crash last year. Except for losing track of who I dealt with (and for what), I haven't missed the old stuff too much.
Though I did just see something about a battery... Maybe I should disappear whilst I still can.
Wishing you well for your re-trucking. (Studies, projects, engine blowups, ... masochism!)
