Piston and Cyl prep

Prior to installing new pistons and rings into fresh cylinders, what is the proper preparation? I have heard too much lube can affect initial wear. Do I lightly wipe oil to the surface of the rings and cyl with a clean rag, is that correct?

Thanks

I oil down thw walls by hand. and do the same thing with the rings ( squirt some on with a squirt type oil can ). I don't submerge the pistons in oil. Position the rings where I want them on the pistons and slide them in the holes. I only use tapered ring compressors as I have damaged rings in the past using squeeze type compressers. I use a good grade of 10W40 oil as brakw-in oil.

Do it ANY way you want but never dry. Big thread about this last week so I won't repeat much except that if you will CLEAN the bores ( who cares how--ATF, thinner, 4 rolls of paper towels- spend two days in each hole if you are &%$#--whatever! -again who cares? ) Put some oil--weight does not matter!!!!!!! on the piston and rings--lightly oil the bore with WHATEVER--put her in --You did good --keep working on it --no worry OK? Way more important to get ring gap right and rings on RIGHT SIDE UP now ain't it?All that about Wd40, detergent, non detergent, ATF, dipping, etc. 30 wt, 10w-30- no synthentic etc etc is just yammering! MILLIONS of engines have been put together by thousands of guys that don't know anything and have run fast enough to scare most folks into a seizure OK?? BASICS___NOTHING FANCY will save you--Basics will!!! Every time. I am so tired of folks over teching everything--golf, deer hunting, etc--just have some fun, do the basics that have been proven by decades of results and quit over teching your lives. Guy that asked the question is not included in my target rant audience--he is innocent.

I still do it the old way, clean coffee can, dump a qt of 30 wt oil in and I submerge the piston past the pin and let it sit then install using a tapered compressor. I use assebly lube on the bearing. The engine may sit for a week or better before install this way gives me peace of mind but may not be state of the art.
I have never lost an engine doing this.

Never use a rag on a engine, matter of fact. Keep all rags far from your engine. Lint free paper towels only.

Check ring gap on each ring firstin it's bore.
Then check ring fit in each piston.
Then I lub the cly walls with 10W hydralic oil.
Then spray the rings with WD40 or a little 10W oil. That's it for lub.
