Best 350 pistons/liners for rebuild

Jake Winn · Dec 26, 2008

I have a 350 engine i need to rebuild. #2 piston is badly stuck and there is a ridge in the other cylinders. What is the best rebuild kit out there. I can get a Tisco kit through work with pistons, liners, bearings, gaskets, valves, springs and keepers. These appear to be a stepped head piston. Has anyone used one of these kits and had what kind of luck did you have?

Also I have pulled wet liners from engines before but never a dry sleeve? Whats the procedure? I have access to a full shop for tools so thats not a problem.

Thanks for any help. Happy Holidays!!

Tiscos are as good as any. They are commonly used. The piston should probably be removed prior to sleeve removal. The piston is probably swelling up the sleeve. This will make it near impossible to get out. Mechanical destruction of the ring area of the piston, drilling it out with multiple holes until it can be broken ouy works. A sleeve puller is needed to get the dry sleeves out the top. See images of them in Search For archives. Put H sleeve puller in the box. Good luck, they are pretty easy to work on. JimN

Thanks. I have overhauled many Deere diesel engines with wet sleeves and have used sleeve pullers on them. When putting the new sleeves in, whats the best way? Will heating the block and cooling the sleeve work? I have a lathe and can turn out puller/pusher disks.

Most freeze the liners and warm the block with a heat lamp or other modest source to just above room temp. The cylinder cast bores are often select fit meaning they are not all the same. Each should have a letter stamped near the rim of the sleeve on the deck. The letters are from A to D with A being smallest select fit. If you have a C or D hole, it might be big enough to not have a good fit with the sleeeves supplied in the kit. The answer might be to have one sleeve made (LA Sleeve, or other good source) or find a sleeve that is larger in a kit. Selecting between the variability in the sleeves supplied can also do it. Any sleeve that slides in 3/4 of the way without heating or cooling, will be OK. if it pushes in with hand pressure W/O freezing, I would not do it. The rims fracture and the sleeve sucks into the bottom end. Very not good. JimN
