Thanks for the suggestion, Scott. I plan to do a little more than that.
Last time I had the engine dropped the liners were still pretty good.
Besides cylinder heads, no matter how good the cylinder liners are at
150k miles it may be a good idea to just replace them. I am not too sure
about this though. If I replace them I may be tossing something I should
not. I think the better bet is to replace them.
It is much more difficult to deal with the bottom block of course. I will
see if I see any sign of need to tear it down. I am not experienced in
dealing with the block or any block. I hope I do not need to do anything
to it. I know I should not take chances. I will see when the engine is
dropped.
Still no Gerry mails, except the one from you.
