Installation of engine

The workshop manual recommends you to [remove and] install the engine from below, on its subframe and with flanged-on transmission as shown in the picture above. I would recommend you do that, unfortunately I didn’t have the space/equipment necessary for it. If you remove/install the engine from above, there are a lot of jiggling and risks for damaging something.

If you drop the engine in from above, as I did, it’ll be tight. Don’t have the cylinder head cover mounted, and if possible, not even the cylinder head. With only the engine block you minimize the jiggling towards the rear engine compartment and the dividing wall.

It’s very tight between the oil pan and the subframe. If have the correct oil pan screw plug, i.e. the one with a protruding hex-nut, and not a flat insex screw plug, you may need to remove it. In my case it hit the subframe. I also loosened up the screws for the dividing wall with the brake booster so that I could move it around while jiggling the engine into position.

Once the motor was in place, but before I tightened the motor mounts, I enjoyed myself by giving the motor a couple of good jolts in an attempt to get it to "settle".

Before the installation, ensure:

• you have mounted as much as possible in the engine bay, or at least test mounted, but on the same time taking into consideration that you want to have as little as possible in there since it may be in the way when you install the engine,
• the reversing light cable and its bracket are in place, and
• all screws on the engine are tightened, incl the forward engine mount’s upper screw.

In the gallery below you have some pictures taken soon after the operation. They also show some of the auxiliary systems, such as the carburetor and fuel pump, which I don't cover in this article. If you are missing any clarifying picture, send me a message and I will try to add what you need.
