When evaluating scored or streaky cylinder walls, it is often difficult for a workshop to decide whether the damage is already extensive and requires removal or repair of the engine, or whether the evidence is harm\u00adless. The following instructions will help in making an expert and correct decision.<\/div>\n<\/div>\n<\/td>\n

With regard to marks on cylinder walls, the first im\u00adportant difference is between „optical streaks” and „seizure streaks”. As a rule, „optical streaks” are about 3 mm wide, they are produced by the piston ring gaps and do not destroy honing structure; „seizure streaks”, however, obliterate honing structure.<\/div>\n
With streaks in direction of „land” (in direction of piston pin) shaft streaks or seizures are not possible, since there is no contact between piston skirt and cylinder liner.<\/div>\n<\/div>\n<\/td>\n
