Comes in a white bottle with a blue cap. Lube the side that touches the crank ONLY. If you lube the other side, chances are the bearing with spin. Make sure you clean them up really well before installing. Even though they are packaged good, they can still have dirt on them. Basically by cleaning them up you are inspecting them for any defects or damages.

Plasti-gauge is pretty simple. Find out the factory clearance, get the correct plasti-gauge, assemble the crank/rods/block DRY. DO NOT... READ: DO FUCKING NOT turn the crank over dry. I'm guessing you are replacing the main bearings too? Or is the crank still bolted into the block, untouched? Disassemble and check the plasti-gauge with the gauge on the packaging that it comes in. I'm sure it will be in spec. If not, measure the bearings seeing those are the easiest to fuck up, then check crank journal and rod journal sizes. Go from there.

2. Use ATF (automatic transmission fluid). Put some on a non-dust/lint rag/towel and wipe out the cylinders for any dirt/debris. Coat the entire piston in ATF, rings and all. I usually cut a QT bottle in half and dunk the whole piston in, rings and all while attached to the rod and the rod is sticking out of the container. Lube up all 4 as its much easier to work with it even though the other 3 are used. It doesnt hurt anything, just makes things much easier and better safe then sorry.

3. Are you putting the piston on the rod yourself? Minor lube on the pin will help, DO NOT force the pin into the piston/rod with a hammer or any other type of tooling. Easiest way I found was throw the pin in the freezer for 20mins, then heat the rod slightly with a torch, dont get it red, just warm. Put the pin lock rings in one side of the piston, when the rod is ready, the pin should slip right in and sit against the lock ring, then just put the lock rings in the other side and you should be good to go. Just make sure there isnt much side to side play and the piston/rod move freely. Compare to the 3 used ones.

Disclaimer: This is just part of my methods/techniques, they are my opinion, some have different ways of doing things. I'm not saying these ways are the only or best way of doing it. I just found it to be the way I am most comfortable with. Take them as you wish. Good luck!

i do pretty much the same thing. i usually dont coat the piston's in anything tho coating the cylender's is usually goo enough most the time we dont even do that
