    Piston rings without pulling engine

    So I just built this motor about 6k miles ago, you can see the whole process in my build thread. The car recently stopped on me on the highway. There is smoke coming out of the dipstick tube, and exhaust, and the spark plug was oily. This means i did some damage which was probably a result of sucking water through my CAI a couple weeks ago. So i imagine my piston rings are trash on that cylinder, there's no way 'its my valve seals because the head is brand new.

    my question is can i re-ring the piston (piston 4) without pulling the engine, and without sending the block back to the machine shop, because it was just bored .040 over when i built it 6k miles ago. Im thinking i should be able to get away with a hone only? what do you guys think?

    Normally i would just pull the engine, however if i could do it in the car that would be much easier for me working alone.

    I did mine 3 years ago. I did everything except main bearings. I left the transmission in also which made it a little harder but it can be done. If you smoked your ring I would be leary with just a hone. It might be fine but I would mic it and go from there. My 2 cents.

    Yeah that makes sense, i've seen my dad re-ring an engine we built once that didn't seal properly without taking it out of the car and have it run fine after. I suspect their shouldn't be too much wear on the cylinder walls but there's always a chance they could be out of round.

    You can do it in frame for sure... but for the effort it takes getting the tcc and pan sealed up nicely why not just pull it and do it properly?

    Well I will be doing it on a lift, so I figured it wouldn't be too hard getting the pan and tcc on. I've done a tcc before and it took some patience but wasn't too bad.

    Why don't you disconnect the front subframe and raise the rest of the car on the lift, then you can easily do it all out of the car. No need for a hoist.

    If you have a lift its not bad...but in a driveway its easier to pull the engine and get it on a stand.
