Default Pulling the engine

Looks like I will have to rebuild the LS2 (76k miles) in my Procharged 2005. There is some internal damage, yet to be determined, but probably a piston issue. Bought the car new in 2005 and has been modded since 2006, so I cannot cry too much!

Are there any details I should be aware of? I think I am going to remove the intake and heads while the engine is still in the car, then pull the short block and rebuild using forged internals.

I am also thinking about a good blower cam and valve train. Any suggestions?

Thanks

You may want to pull it from the bottom and go thru diff and torque tube.

Just a thought.

It is easier to remove the engine and cradle from the bottom if you have the equipment to raise the car off of the cradle high enough to remove the engine from underneath. It would still be an advantage to remove the intake, accessory drive and heads prior to dropping it. It will be easier to maneuver from under the car.

That is what I was thinking. I do have a lift but ceiling height in my garage limits it to about 32 inches off the floor. Thinking that is enough. Also have a tranny jack, so I feel that would make it easier.

I am going to go ahead and pull the intake and heads, and, of course, all the ProCharger plumbing and accessories before dropping her down.

Piece of cake, right

Unless you have the proper equipment to lower it from the bottom, doing it from the top is a whole lot easier and not very difficult. I've done it more times than I care to remember and can usually get it out in just under 5 hours.

it can be done through the top, not very hard at all really. I pulled mine from the top last year, now this year is drive line, which I dropped out while on jack stands. wish I had a 2 post lift though!

After working on disassembling some of the engine components this morning, I have decided to pull it from the top. I hope to have it down to the short block tomorrow, then rent a hoist and haul it out.

Then, the decisions on what to re-install ??

Definitely forged, and a decent street blower cam.

This story sounds familiar. Procharged car, broke motor, down to shortblock, will pull out the top out of necessity. I am going back with an LS3 top end on something like a 408. I will use a cam like Patrick G has in is grandsport.

Yes, that's correct.

Doing this will I have to drop the cradle or remove the steering rack? I have a 10% OD 8 rib balancer and it all looks tight. Its coming out one way or another tomorrow so I'll update the thread with my process.

I've always found it a LOT easier to just drop the cradle, although you will need a transmission jack to help with the process if you don't already have one. Apparently some people have gotten the engine out by pulling the rack but I think that doesn't give you as much room to maneuver around.

You'll also need to disconnect the front shocks and upper control arms but that's pretty easy to do. Don't forget to disconnect the steering shaft from the PS pump either, which I believe is an 11mm bolt.

I managed to pull mine (and replace) without either dropping the cradle or removing the steering rack. I had the OEM balancer, so that may have been the key to make it possible.
Then again, I haven't had as many experiences doing this as Christopher. He obviously has had more opportunities to find shortcuts and time saving methods.

I finally got mine out yesterday. With the 8 rib OD balancer I had to drop the cradle a couple inches but the whole thing wasnt too bad.
