Sorry for the silence - I had to fix some stuff in the garden/house...
@graham: you're right - with functional tappets they should stay 'full' after first running in. And when I checked last time they were all firm (rocker cover off and pushed each with a plastic pin).
@ SVC: My plan was to check compression on all cylinders this week - but ran short of time
I gave it a good italian road test Monday :-)
I seem to have power.
But I noticed a couple of times: when accelerating modestly I seem to hear clacking/knocking noise following revs - indicating trouble...
So, a couple of theories:
1. bent rod on cylinder 3
-> seems valid as I can hear reduction of noise when removing coil on #3
-> need to confirm with compression test
2. lazy valve (i.e. having trouble returning completely to seat)
-> no experience with this - but cant understand how the cold start scenario fits with this (noise - silent - then noise; see above)
-> this would require head off to check I guess :-/
3. loose/spongy tappets
-> I don't believe in this theory anymore.
Went for Danish MOT today - my CO was now ok (failed last time - I believe its because I replaced injector on cylinder 1).
However the car failed on airbag lamp on :-(
(not allowed in DK apparently)
