Do i need to remove or lower front cross member to remove engine?
Hi Guys,
looking into the requirements to pull the motor from my Evo 8.
Appears from research its arguably better to drop the engine with tranny and transfer case in situ out of the bottom vs taking it from the top.
taking from the top requires that the TC is removed from the tranny, set aside out of the way then pull the motor with tranny from the top tilting on the hoist so that the engine is higher than the tranny at around a 45 degree angle.
can anyone advise if with both Top and Bottom engine removal methods the subframe will need to be removed/lowered as I would ideally go the route where the subframe will not need to be touched?
The reason I am asking and hoping to avoid this is because there are 2 studs on the subframe that are concealed in the chassis which is welded in place and a nut on the underside which is what you unscrew to lower the subframe once the other subframe bolts are off.
There is a common issue where by these captive bolts break off of their welds and you are left in a situation where you may need to cut an access hole in the strut and tack weld the bolt back down so you can get the nut off or back on.
appreciate it may seem a little silly me worrying about this in the grand scheme of things however i don’t really have access to welding equipment nor the experience to welding it back into place should the inevitable happen.
Cheers guys, any comments, tips and guidance welcomed!

Its really a preference thing and what access to tools are at your disposal. If you want to pull from the top a cherry picker as well as leveler is required for obvious reasons. In that case being that its coming from the top subframe can stay in place. You can also get it out the bottom while leaving the subframe in place. Unbolt the xcase and leave it in and then lower the oil pan onto a moving dolly/ lift table. Then lower it out. If you have a lift raise the car up. No lift get the vehicle as high as possible and you should be able to snake it out. Might need to angle it to get past the radiator core support but if should work fine.
Here's the catch. Like most things in life you have options and there are pros and cons to both. I used to always do it putting from above but after doing it dropping it out I think that's my new method. That being said you also will need to pull your intake manifold and exhaust manifold off if you plan to drop from below while leaving subframe in there. Hope this is helpful!

I have a cherry picker, axel stands and trolly Jack - I wish I had a lift!
So if I pull from above with cherry picker and leveler will I need to remove the TC from tranny before I pull it up or will it all come together? I will remove both manifolds anyhow.
When you describe the process to remove from below, does it make it easier if you remove/Lower the crossmember?
Out of interest have you ever had issues with these bolts breaking off their welds and being unable to remove/screw back the nut?

I have done it both ways and removing the subframe is really a 30 min job that makes everything else just so much easier... Just make a mark on the rack input so that you can re attach the steering shaft back on in the identical position..

When you say both ways did you mean you also removed subframe when pulling from top?

No, I removed the engine out the top with the subframe on the car.. However that was with the head off.. I am not sure how much more difficult it would have been with the head and intake on..
I prefer to take the subframe off and then just lower the car onto the engine if you know what I mean..

I've done it from the top(and will be doing it again shortly) and I didn't need to lower the subframe, Just unbolt the tcase and push it aside. Use the engine lift with load leveler. I'd recommended a friend or 2 to assist as it makes life easier. You'll need to remove the radiator.

I pulled it out the top. It was easy with the intake and exh manifolds off, accessories off, radiator out. Head still on the car. Didn't touch the subframe. Haven't tried dropping it out the bottom. FWIW, I didn't have any help pulling it out in a small garage with a cherry picker/leveler. Would have been nice with an extra set of hands, but definitely not necessary. I had a friend help me guide it in and line up a couple of the mounts when it came time to re-install.
