Ok so my Engine is blowin out white smoke every once in a while. We have narrowed it down to either headgasket or rings or seals on the turbo are bad. Most likley the seals.. Anyways to be safe in january im getting pistons and rods and sleaving and (boreing?) the block out to a 2.4? So anyone who has taken their motor out and put it back together would you recommend any steps to be taken over others? Any tips so i can avoid as many problems as possible? Do you need to completly detach the tranny? Im gonna go with RRMs piston and rods maybe even do cams while im at it anyone have any experience with those? All help is greatly appreciated!

Don't think you can go as far as a 2.4 liter. I got mine bored out to the safe maximum and its only like a 2.1-2.2 liter at most.

You can go as far as slightly over 2.0. Run a search on overboring. You'll be displacing as much as the water jackets hold if you get to cavalier. IMO a bad way to try gaining power with the Lancer. The 94 is at its max already.

Hobie's right, you can only bore it out another .1 maximum. Remember, our block is a bored out 1.8 Mirage engine. Do some online shopping, I guarantee you can get better pricing than RRM.

You can bore it 0.020.

Yeah, I don't know exactly about the max, but I'll take Amby's word for it. The issue would then be that you'd have to get matching pistons without actually displacing much more. IMO, the expendeture would not be worth the gain.

if it's just a headgasket, why remove the pistons and bore the cylinders? The gasket is easily accessible from the top, it just takes some time and a bucket for the coolant Sorry... I really hate coolant If it's the turbo seals, seems like that would be a bazillion times easier to fix (having taken this engine apart more than a few times, I assure you this is the case).

I'm pretty sure amby is right that you can only go about 0.020 over (maybe 0.040?), not worth it in terms of gains, IMO. It's good to know, though, should you have an issue that requires boring the cylinders.


And lastly, if you DO decide to get pistons anyway, there's no reason to remove the engine, all the work can be done with the engein safely mounted under the hood.

k then i wont bore anything ill just put in pistons and rods.. So i can put the pistons in without taking the motor out, what about rods? Im pretty sure its just the turbo seals cause the exaust smells like gas not water so i dont think its the headgasket.. There is some fuel in my oil so it could be rings, its not a stuck injector or anything cause the plugs are fine

The rods are connected to the pistons- you take the head off, then the oil pan (the big one, not the little black one that you change your oil from) and push the pistons out the top.

Please tell me you have a shop doing this for you (please).

If you have an engine hoist and stand, IMO it was easier taking the engine out, especially when having to put the new pistons in with the new rings. With the engine out it was a PITA, and with the engine in, I almost gave up.
