Hi,
Newbie here. I've decided on a refresh and the builder says I can save some money by just bringing him the motor. I am really trying to learn about my car, so I want the experience of taking the motor and transmission out of the car. I have the space, desire and tools, but lack the knowledge. Has anyone ever seen a thread (with pics preferably) about removing the motor and trans? How easy/hard is it?
Written directions would work too if they are thorough.
Thanks alot.

From another Turbo Buick DIY:

  1. Put the vehicle up on jack stands, set the e-brake, scotch the rear wheels.
  2. Unhook the battery.
  3. Drain the oil (leave the filter on to prevent a mess)
  4. Remove the exhaust crossover pipe,transmission dust cover, torque convertor bolts, starter bolts (I always just leave the starting wiring on), motor mount bolts, bellhousing bolts (if you have problems getting to the two top bellhousing bolts remove the coil pack and get them from the top)(I do the "underneath" stuff first because after you take the radiator hoses/oil cooler hoses off you will have a mess to lay in)
  5. Remove the downpipe from the turbo
  6. Remove the MAF sensor and pipe.
  7. Remove the intercooler.
  8. Remove the alternator.
  9. Remover the A/C compressor and two braces that run from the header to the
    compressor.
  10. Remove the belt and then belt tensioner.
  11. Remove the aluminum bracket that holds the power steering pump
    assembly.(This is attached to the head)Lay the assembly to the side and tie
    out of the way with a wire or zip strap.
  12. Remover radiator hoses.
  13. Unhook heater hoses from heater core (be careful, they are usually stuck
    pretty good)
  14. Unhook fuel lines (I always unhook the rubber lines between the frame
    and engine)
  15. Unhook your wiring (I always wait and pull the engine out a little bit
    to get to the grounds on the back of the head), Unhook gas pedal and cruise
    control cables. Don't forget the wires that run down the front cover to the
    crank sensor.
  16. Unhook the oil cooler lines (messy time)
  17. Hook up engine hoist
  18. Place jack under transmission.
  19. Raise up a little, unhook ground wires on passenger side head.
  20. Pull the rest of the way out.
 
I have done it several times. It is a simple job. You spend all of the time disconnecting eletrical connections, lines, and exhaust. If you're new to pulling engines take your own pictures as you go. Also marking connections so you know where they go. A picture is worth a thousand words when you can't figure out where something goes.
 
Thanks Guys. I'll let you know how it goes; plan to get started right after Christmas!
 
Since you're new at this I'd suggest that you get a camera and take lots of pics for refference. Jeff's directions are great but pics will help you if you don't know all of the parts. Also label everything so you know where it goes the first time.;)
 
I had never worked on a TR or really any car for that matter and had no trouble getting mine out. Now getting it back in and running good is a completely different story. TAKE PICTURES AND LABEL EVERYTHING. I can't stress that enough. It seems like there thousands of connections when trying to get it back together.
 
The AC compressor can just be layed over in the fenderwell, no need to disconnect it unless you plan on removing the AC altogether. Get ziplock bags and a sharpie. Write on the bag where the bolts come off from. A few big plastic bins work good to put all the parts in as you remove them.
 
Pronto: that was exactly my plan - ziplock bags and a sharpie! plus a bunch of pics.
 
Pay attention to # 15 the ground wires are bolted to the back of the heads off the wire harness. It is really easy to pull the motor up and rip these ring connectors off. If your removing the engine and trans take the front bumper off and if your header panel is nice remove it. It's better to take it off than have to get it repaired after the Transmission tail wacks it.
 
If your not going to do work on the transmission I would leave it in the car and just pull the motor.
 
If you have a lift it's not bad. You can spot that bolt from the back of the transmission looking forward , you need about 3 ft of extensions & a swivel socket to reach it. Crack it loose then run it out with a air ratchet.
 
Thanks I got it out but made a major mistake ... I forgot to put the jack under the trans and left it hanging when I pulled the motor ... the jack is under it now .. do u think I damaged anything ? I know newbie mistake
 
unhook everything, drain the fluids, lift out.


there are about a million details that you have to figure out along the way, but in the end that's all there is to it... i learned how to pull engines on a 78 Cutlass when i was 14 with only basic hand tools and a come-a-long hooked to a big branch on an oak tree and the internet was a decade away from existing yet, and i figured it out.. so get to it..
