Engine Removal

[Avetiso]

Going to start the process of pulling the engine from my parts car. I could probably figure it out as I go, but, considering that I'll be on my back against cold concrete for a lot of the time, I'd like to know what to do before I go in.

Can anybody write out the steps to removing the engine with transmission as one piece from the car? Just a list of things that need to be done and anything I need to know ahead of time.

Thanks.

Make sure to disconnect the exhaust manifold, it's impossible to get it out with the rear 3 still installed

Oh wait, you wanna take them out together? We did it with the trans removed...

Take the core support off, that will help big time, drop the subframe and lift the front end of the car. Let the subframe w/engine go down to the floor. Roll car back and support frame rails

I need to pull it from the top. Lower suspension is all mangled from the accident.

Well definitely take the core support off so you can pull it out straight. I recommend disconnecting the trans from the engine but that is up to you

Core support should be held to fenders and frame rail, easy to remove (the two things in the left bottom of the attached diagram)

Now THAT'S an awesome picture.

Seeing an angle grinder in the picture scares me! :blink

Dario shouldn't need it. I have a feeling the guy who posted that pic I found was an idiot and doesn't understand how to take things apart correctly

Edit: that pic is an E36, but you get the idea

[cakM3]

It's funny looking at that picture because you can see the broken hammer by the angle grinder. The guy probably tried using that hammer until the head snapped off, hence the angle grinder...;)

I would remove the engine and trans as one piece.

[Hermes]

If you pull it straight out, then yes you can leave everything installed. I'm just saying that if you are to lift and remove by trying to clear the core support it's a huge PITA with the exhaust and trans installed (if you can even manage to do it).

We did it with 3 guys, trans removed already, and about 30 minutes of yelling at the car before we decided to remove the exhaust. After that point it took 30 seconds. I can't imagine how long it would take (if even possible) without those items removed. You hit both the trans tunnel and subframe when you try to lift/angle it up, so something has to go

edit: Dario, make sure to purge the AC system before you start taking core support stuff apart

[Vas]

Oh for sure I would take apart the front end and then pull straight out. Going over the radiator support sounds like a PITA.

Disconnect manifolds from collectors, disconnect engine harness from DME and drape it over the VC, remove motor mount bolts, discharge A/C system and remove AC compressor and PS pump. Then crawl underneath and remove the transmission bolts (or remove driveshaft and trans crossmember). Engine should be free to wiggle and lift out, transmission can come out the same way. With the help of my friend, the M54 can be pulled in 2 hours or less.

I have a theory.. it must be bunnies!

Actually my crazy theory is the person used the angle grinder to cut off the hammer head so he (we must assume it's a he, yeah?) could use the hammer's handle for leverage.

I used a sledge hammer when i helped pull a m70 v12 with my cousin. When in doubt or frustrated, hit the crap out of it and hope it comes off.

In all seriousness, that was true, but dont use a sledge LOL.

Do you have a bentley manual?

[Hermes]

M70 - E31? Stupid car with core support that's not removable

[3ZHP]

I used a sledge hammer

In laymen s terms, its reffed to as a BFH

Do you have a bentley manual? I just sent him the chapter out of mine

Dario,

This thread might help

See post #39 where Amsel agrees with me to remove the core support

E32.

Yep beat the shizz out of the core support to get the motor out. The goal was to take the m70 and make a v12 coffee table, and the car was going to be crushed so we were allowed to go ham on it. :rofl

[Hermes]

That's even worse... I assume you pulled the hood off first?

[Avetiso]

Front end and clip are already removed.

Looking good. You can see the hole for the hook in the front, there should be another hole by where the starter is at the back of the block
