I had several issues installing new dry sleeves in my 640 (134 motor). Sleeves came in a kit with new pistons. I put them on dry ice for 24h, heated the block with oxy/ac (the occasional popping noise while heating the block was a bit un-nerving..), and put the sleeve in directly from the cooler to the block. I used sea foam lubricating/penetration oil to lube the sleeve. That might have been a mistake. Anyway, I had to pound the tar out of these things with a 2x4 on top, breaking a lot of boards before finally getting them in. I'm still doing countless measurements for out-of-round (0.003 tolerance) and taper (0.008 tolerance), but it seems to be in spec, although pounding on it so hard clearly had an effect. Placing the piston inside of the one that received the most pounding, the piston was very tight, lubed with the same sea-foam oil. I was thinking, oh no, big trouble. But then I lubed it with motor oil and it moved up in down in the sleeve no problem.
Do you think the sleeves went in so hard because I used the sea foam oil instead of motor oil to lube the outside sleeve upon installation? Is that going to be a problem if I have to take them out in 20 years?
If it turns out to be slightly out of spec for out-of-round or taper, should I use a hone to make it better, or just pull it out and start over with a new sleeve?
I am interested in any of your thoughts on this topic.
Thanks!
