@ahubbard117 I say, that you can compress the piston rings on the working table, not using as table your block. As you are trying to compress the rings, the rod is hitting the inside of your block, the place where the piston goes up and down. With no offence...
@tasis2 - The connecting rod will not hurt the cylinder wall. There was not enough force being applied. The way I demonstrated is an old school way of installing a piston. There are much better tools out, but at the time, I just used what my dad had in the shop instead of buying another tool....
@ahubbard117 I didn't want to insult your way, but today, even a hair on the cylinder wall, does damage...
You can't see it now, but in the future, tha place that will fail will be that small hit !!!\
Anyway, I shouldn't be so rough with it, not all engines are so delicate. And because I happen to be a tuner, and we expect much more from our racing engines, but sometimes, you just loose our minds, chasing and the last hp, and also to be reliable... Keep up !!!
@tasis2 - No insult taken :). I am aware that scratches in the cylinder wall can cause damage, but, for what I was doing, it wasn't going to hurt that particular motor lol.
@tasis2 You are right and wrong. About your comment: "I didn't want to insult your way, but today, even a hair on the cylinder wall, does damage...'' First, you are right I agree with you if we talk about Honda and Toyota engines, or other fucking toy fake engines... Second, you are wrong if you are talking about all engines, because with MITSUBISHI MOTORS, YOU HAVE NOT TO WORRY ABOUT DAMAGE. Third, yes I am trying to insult, and what??? Thanks.
@tasis2 most times when rebuilding an engine you use FORGED aluminium pistons/con rods with CAST IRON sleeves. the iron being much harder and the aluminium being much softer. they will not scratch each other without considerable force
@youngCHEVYboi - Machine shop did. They just gave me instructions on how to put it together. My 3.8 SC motor is being built by them, I don't have the time to do it on this project.
Great man, How hard is it to replace pistons? Im thinking of doing it on a couple of cheap engines before i go on to my Nissan SR20DET. How hard is it on a scale from 1-10? Thank you
@IceCold720 - Pistons on my 5.4 were fairly easy to install. You just need the right tool to compress the rings. I'm sure most motors are very similar.
i don't see why forged pistons would damage the block faster, forged pistons expand less and isn't it the piston rings that contact the cylinder wall and not the piston. if so then there isn't a problem using forged.
@ahubbard117 i understand where you are coming from, really i do. but i am studying mechanical engineering and i cant see why it would make a difference. but at least you saved extra money from not buying forged pistons.
@bobbz16 Correction - Forged pistons expand at a greater rate than non forged ones. You have to account for that expansion in the clearances machines into the bore.
The pistons were oiled previously. My machine shop already checked the gaps etc so the only thing I had to do was assemble the whole package. The block was bored out, then honed.
What do u do if the pistion is too loose inside the cylinder? Would u need to get bigger pistons?

Sorry man, but till the time you compress the piston rings, the connecting rod, has hit many times the sleeves...
Not so good...

Nope, didn't need to heat the block.
The pistons were oiled previously. My machine shop already checked the gaps etc so the only thing I had to do was assemble the whole package. The block was bored out, then honed.

marcosbullock 2 years ago
@marcosbullock Why would you heat the block?
matgonjinn 1 year ago
@matgonjinn Metal expends when heated. Pistons are a TIGHT fit so if you heat the block just a tad it'll make the pistons fall right in.
marcosbullock 1 year ago
@marcosbullock - Hmm, no has ever told me to heat the block. But you are correct, metal does expand. Thoughts to keep in mind for the next build lol.
ahubbard117 1 year ago
Hello,
1.On the piston install, I would use piston ring pliers to make it very easy .
I also noticed you did not oil the device you were using or the rings, dip the pistons in oil or spray w40, makes them glide on ice.
2. On the rings, insert them into the cylinder to check the gap to manufacturers specs..
3.hone the walls are best done with cross hones balls. The compression jumps several psi and ring seating is instant.
