Last winter was I rebuilding the engine (pistons / valve mapping / etc...), so I wanted to check the valve again, to make sure they is within accepted limits.

May 2018 (536792km)
1 - 0,10 - 0,15
2 - rundt 0,18
3 - 0,10 - 0,15
4 - rundt 0,18
5 - litt mere enn 0,10
6 - litt mindre enn 0,10
7 - rundt 0,18
8 - 0,10 - 0,15

Today (560812km)
1 In : 0,18 (2,80)
2 in : 0,14
3 in : 16-17
4 in : 0,14

1 ex : 0,14
2 ex : 0,14
3 ex : 0,16-0,17
4 ex : 0,19 (shims 2,40)

After reshimming in 1 and aux 4):
1 in : 0,11-0,12 (shims 2,85)
2 in : 0,14
3 in : 0,16-0,17
4 in : 0,14

1 ex : 0,11-0,12
2 ex : 0,14
3 ex : 0,16-0,17
4 ex : 0,14 (Shims 2,45)0812

Now I plan to follow normal km interval for valve check, agree?
