I have a 95 5EK with about 975,000 miles. 2nd owner, put 500K on it, never overheated, reg service done 15K max, either way a pretty easy life. Had the injector cup o-rings go bad and filled the cooling system with fuel. Had them changed and then a while later the oil started getting coolant in it. Well now I want to rebuild it and was wondering if I used the old liners and had then honed and such, if I replaced them in the same holes would I need to do counterbores? I am looking for some easy tricks to keep the rebuild cost down yet still get reliability.
