cost for a piston re-ring?

im pretty sure one of my piston rings are leaking.
im blowin smoke out the tailpipe (yes smoke not vapor)

question 1) how do you perform a compression test?
question 2) how much would it cost to rering the pistions?
question 3) if i did it myself, how would i go about doing it?


im not mechanically dumb or anything i know the basics and a little more. i just want to double check and be sure before i do anything to it seeing as its my daily driver

1st question I can answer with more knowledge. The rest, not so much.

You'll need a compression tester (of course), With a good, charged battery you'll need to disable the fuel pump and ignition system so it doesn't actually spray fuel and spark while testing. Remove all the spark plugs from the engine. Install the compression tester into the first cylinder, and while holding open the throttle, crank the engine over several times. Repeat for the remaining cylinders, cranking the same number of times and for the same length of time on each cylinder. Though don't let the starter get too overloaded at any one time. Jot down the pressure reading for each cylinder, all should be within 10% or so of each other. The actual PSI can vary based on many outside factors. Though as a general rule, should at least be over 100. If any are out of that range, squirt a bit of oil through the spark plug hole into the cylinder that is off.

Test that cylinder again and see if the compression has gone up. The oil should temporarily seal the rings, and confirm whether they are bad.

Q 3. Basically a complete tear down of the engine. I'll let someone else fill in the details.

Pretty sure it's a little more involved than just snapping new rings onto the pistons. If you're going to tear down an engine that far, at a minimum new rod bearings should be installed, which means the crank should be machined as well. And next, before reinstalling the crank, rods and pistons, the bores need to be machined so that they're perfectly round again. Basically you're in it for a rebuilt engine. I'm no engine builder but I do keep a Haynes manual and a stack of MM&FF magazines next to the toilet

Yeah the newer engine will drop right in, and pretty sure your current pcm can be used once it's tuned. There's other small things too, like fuel system stuff that might need to be switched over. Just search "engine swaps" or something like that on this forum and you should be able to find everything you need to know.
