Hmm yeah I'm confused to be honest, the valve clearances do check out, they're what they should be. I'm not aware of any rings being broken, I was careful inserting them, using a proper ring compressor tool. If anything broke, it wasn't audible...
No, I don't *want* to take the head off, just not sure how one cylinder can not be reading any compression at all, or aware of any way to find out or remedy it without doing so :/
I guess next step is get over my fear of spraying down the hole after last time, knowing this time that the timing is spot on all over and it's not going to backfire and make flames again. And see if it starts from there. Doesn't help we're having such cold days at the moment, but got to try!
Maybe I was lucky with my other Alfa, the GT junior. After rebuilding the engine on that one it started first time and has been ever so reliable ever since. It's got lucky number 7 on the side as it's rebelling against everybody asking "doesn't it break down?" , "don't bits fall off?", "doesn't it rust?" and the usual 'Italian car comments' and not actually ever going wrong. This one however has 666 on the side initially because I thought it was a bit of a beast (compared to anything else I've driven anyway) but now I've decided it's the devil in car form...
Will get back on here once I've tried a little spray into the plenum to compensate for the lack of CSI functionality.
Out of curiosity what would 'normal' compression be? Good to know it might improve with use regarding the rings being seated.
