When I got my 1981 wagon.. for $2000 I immediately ordered $200 worth of the Factory Shop manuals . Worth every penny. But I also like the Haynes Manual for nice pictures ( of the stuff it addresses )...
I certainly would not start an engine job without the Factory Manuals, either from a friend, library, or something....and you will still have questions to bring here because the are not particularly easy to read/understand.... they may have been written by Germans....
There is lots of info about the sleeves... do several searches to find it..
Some of the decisions need to be put on hold until you take the engine apart and can measure the parts...I love the idea of being able to put new sleeves into an engine... to ' start' from scratch so to speak....
