Are you able to replace the pistons without pulling the motor out of the car? Or would it be easier to take the time and pull the motor out and replace the pistons?

 

Just take the extra effort and pull the engine out. It'll be MUCH easier.

 

I really prefer not to pull the motor out unless I have to. I would have to disconnect the axles, tranny, misc. and it would be a hassle.

Are you replacing the pistons yourself?

Because if you are, and you are too lazy to not want to take the engine out of your car, then I would question the patience it takes to replace those pistons.

Don't short-cut it, just pull the engine.

 

it can be done, but you have to take the tranny off and basically the block just sits in there on the rear / side / front mount. you hone it from teh top. its completely moronic not to just take the whole motor out.

 

pull the engine

It will be a major hassle trying to do it w/o pulling the engine. Just pull the engine and tranny out together, separate the two on the ground, and then put the engine on an engine stand. Then you rotate the engine up and down to get to both the bottom and top of the block quickly and easily.

 

its not hard changing pistons with out pulling the engine out
i would do it
and why the hell do u need to take the trannie out for. you dont take the trannie out

all u do is pull the head off and thats it
take the oil pan, windage tray and oil pickup out and there.
2 bolts for each rod and puch the piston up out of the block
go to autozone and get the thing used to horn the cylinder walls

i mean its not hard at all
if i wanted to change pistons lets say i wated some forged pistons instead of my pr3's i would do it this way
i would not pull the motor out that way too much work and more work than you need to do

 

It could be done leaving it in the bay for sure, but if you have an engine stand and hoist, I would just pull it. Once you have the motor out, it will be much easier to work on.

The only problem with that is that the crank still sits in the motor and when you hone the cylinders, all the fluid you use to hone drips down onto the crank along with the fine metal from the cylinder walls.

Mmmmm...who doesnt love little metal bits floating around in their motor

 

How come you have to hone the cylinders?

Its a general rule that you should change the rings if you are putting new pistons in and you need to hone the cylinders to put in new rings for them to seat properly.

 

don't forget your ridge reamer as well, depending on the carbon build up in the cylinders, you might not be able to get the pistons out with reaming the cylinders as well. Only takes a couple of seconds though, really easy

 

Hey if its your daily driver.Do it right.Buy a extra block on the side.One thats bare if you will.Then build it up from there.Once its done you can sell your current block for more
