Pulling motor from bottom (pics)

As soon as I get more pics downloaded and sorted I will post more.

It is kind of a PITA to do alone! well over 4 hours for me. My fuel lines caused me trouble, one of the quick releases would never come loose so the metal clip ended up mangled. Will I have to replace the whole line? The other parts that took me the longest were finding and popping off all the little places where the wiring harness is clipped on the body and the damned steering column. I could only see 1 bolt holding the steering column together, and the more I lifted the body the more that connection scared me with creaking. But it finally popped out. Getting those brake lines out of the way is a major pain by yourself too!

I think I'm going to do a noob's writeup for this whole thing. I took detailed pics of all the crazy difficult spots I had and I labeled everything. There are a lot of little bits of info I wish I had that the other guides don't have.

You should really do this with a hoist. Lifting the front of the car like that is how bad things happen.

I know, I know, I was just illustrating how it can be done without because I only had one jack to use at the time, the other is at my dad's and I don't own an engine hoist.

I raised my stands every couple inches to be sure I wasnt going to drop it if it slipped, and periodically i wiggled the jack to make sure I was firm EVERYWHERE before lifting AT ALL. I need to get a hoist but it can easily be done without, it just takes a LOT of care to not get anything unbalanced.

It's even easier if you leave the wheels on (= instant dolly). Plus, you won't have to lift the car so high. I carefully lifted mine by a jack in a similar manner. No problem. The jack may creep a very slight amount as the body goes up, but it is not going to go anywhere if the car cannot roll.

noob question- When putting it all back together, how do you make sure everything is 100% exactly aligned? I imagine there's dowels or something, but is it possible to reinstall and not have the sub-frame exactly aligned?

yes there are dowel pins on each side. It cant be installed if its not aligned...i had to have a budy helping me have the strut bolts in place while lowering the front-end before the dowels get in position.

Yeah and shoebox is the man for all those little bits they leave out in the guides!

I had the jack creep a few inches back every 8" or so up. Everytime the jack creeped, I notched up my stands a slot or two, then I would lower, re-adjust, repeat. It only took me 20 min from having my last wire unplugged to lift the body. Personally, it was WAY easier to get to the K-member bolts with the front wheels off. I don't know how a guy could even untorque those bolts without the extra space for leverage. It took me a break-bar and a pipe over the handle to get enough leverage.

Just be careful. Cinder blocks can crumble without warning. I would prefer you not use them....I don't want to see you hurt or worse.

From another thread on going back in....

Once in position, I lowered the body close to the engine, then set the body on jackstands. Then I put a chain across the heads and pulled the engine to the body with the cherry picker(jacking up the tranny as I go up with the cherry picker). Like so...





This way you can easily swing the engine to the alignment pins and put the bolts into the K-member when the entire assembly starts to lift up on the body.

HEY thats what I want to do a write-up for, to anwser the NOOB questions! So everyone feel free to ask them and I will do my best to answer and take pics of it.
Here are the dowels that poke through the top of your engine bay:
They are on your upper A-arms and two nuts snug down on both sides, along with 2 bolts or 2 t45 torx screws.

and don't use vice-grips on brake lines unless you are sure they are coming loose easy or being replaced
then, here are the three bolts on the k-member that drops the whole motor:

Don't use something flimsy like your lug wrench for heavy loads, mine were already loosened and that thing is handy for getting leverage for those bolts that just inch their way out as if they were driven into soft rubber or something

Everyone searching this right now, this is EXACTLY WHY if you use cinder-blocks, don't use them as your SAFETY support or under your jack-stands. They are okay to lift with ONLY IF you have the rest of the car supported EVERY FEW INCHES of the way up, in case the cinder block goes south. Its very rare for one to just break apart under load, they usually do it as weight is being loaded and there is an internal failure, but it still happens. I mean, some of those strong-man exhibitions feature guys punching cinder blocks into dust, i would never trust any of my cars to just chill on them

What I did was jack the whole car up, support it, then lower the k-member and engine from the body with a floor jack. There was plenty of room to reach the big bolts and anything else on the bottom.

thats how we do it in Oklahoma!

lol really they work great but I wouldn't get under any. I thought about going through the trouble of building a lift block out of 2x4's but these were much handy-er. and the wheels in the rear are GREAT for this job, seriously the car pivots perfectly and you can leave it in neutral
