Alfa 164 & 166
I want to change the piston rings. my car has 200 .000 km
Is it worth to do ?
i saw on eper there ist just one "PISTON RINGS SET ", but for CYL/LINER there are different " coulours " 014, 060, 080.
What is the meaning of different coulours.
Can I polish the CYL/LINER , or should i buy a new...
