Case g188D cylinder sealing

thank you

Sometimes those lower bores do erode and if they

are serious you can bore and sleeve that area.

I make my own repair sleeves but there is a

fellow in S D that makes them .

Basically to repair them you need a boring

bar that you can preset the tool as there is

not enough room to use a setup mic inside the

block and the tool won't pass thru the top

bore. Make the repair sleeve for 1.5 to 2

thousandths press fit , make a driver to

install the sleeve. when it is installed you

will have to custom make a tool for the boring

bar to cut the entry chamfer ( much wider

tool than a boring tool).

That sounds expensive, as I'll be paying someone to do the work. How can I tell if it is bad enough? There aren't any specs in the manual for honing that area of the block. You can barely feel a groove on all the cylinders but one, and that one has a more pronounced groove.
