anyone ever install new piston/rod/ring combo with engine still in car? my buddy has a VERY high horsepower stock shortblock Ls1. he's pretty much to the point where he's gonna grenade his motor. just curious but has anyone here ever dropped a piston/rod/ring set in the block with it still in the car? he has 150k+ and plans to hone the cylinders with a manual hone tool before he drops in the set. i've replaced rod bolts with the motor in car before and dont see any trouble with taking a wooden stick and popping the pistons out the top. i do plan to leave the crank in place and replace the rod bearings while i'm down there. any suggestions?

i know that's the right way but i was just curious if anyone has done it this way as sort of a quick fix. i have dont it before to a 4G63T Eclipse and it worked well besides an 8% compression loss on that cylinder. who knows we may be looking at an LQ9 drop instead. lol. but just curious of anyone trying this themselves.

haha i hear that. i guess it would be a good quick fix but not a dependable one. i'm sure he's still gonna do it though. i'll let ya know how it works out. he's spraying a 250 shot so i'll be sure to post some "carnage" pics later.

I did once on an inline 6. The extra few hours to pull it are worth not screwing everything up. I can't imagine wasting the time not to install it right.

I've done ONE piston in the car before, but never a full rebuild without full clean up/hone/deck/clearance check/tolerance check/etc etc etc.
If you plan on doing them all go ahead and save up for the parts, and then another motor. Cause you're gonna need it.
