Thanks Chris again about the very useful link for vacuum lines !!
I have also some progress on my Engine teardown even no hurry, winter is long and plenty of time to make it great again (=
Guys, do you know what could be 1P engine the tolerance limit for clearance between a piston and cylinder wall? I need to figure out if simple piston rings renewal + honing is enough, as said this engine has 301 000km.
Pressures where suprising good when tested those earlier in summer time, but for cylinder nr.1 in other level than for the rest 3 cylinders. Engine was noisy right after start for some time and then get better when warming up. There was a broken hydraulic valve rocket at the cylinder nr.1 exhaust valve which caused clacking noise.
