    Havent settled on a course of action. All I know now is that it has an existing sleeve at 30 in Cyl one and it will need new sleeve in cyl 2........ cyl 3 and 4 bored to 60 to remove gouge.



    Question for someone smarter than me. Can a f134 sleeve be safely bored to 60 over? Is there enough meat? (existing sleeve is bored 30 over)

    Is two different bore sizes a no-no? For example : sleeves at 30 and remaining two cyls 60? Balance problems? other?

    Im not a machine guy so.....need advice.
