Touring it apart!
After the touring was dump here by the seller it was facing the wrong way to easily remove the engine and get it to the garage. Last night my brother came round and we turned the car around which meant I could get on with removing the engine to make it ready for the convertible.
I started work on the car around 11:30 and finished around 19:00, this included lunch of 30-40 mins and some fannying around when the clouds decided to empty on me. In total I think I can cut down an engine removal to just a few hours, provided I have all the tools I need with me (kept leaving some in the garage today), anyway, on with the update.
Why so sad?
First up, bonnet off, nice and simple, couple of bolts on the hinge, one by the gas spring and a spring clip on the gas spring.
No bonnet.
Radiator. Again very simple, couple of screws and of course the water pipes.
No radiator.
Side view.
Air box & throttle body. Couple of bolts, couple of jubilee clips, done.
No airbox.
No throttle body.
Viscous fan. This is simple enough to remove although only if you have the right tool. Luckily for me when I first had a BMW 4 years ago I bought the right tool, a 32mm open ended spanner.
No fan.
The water pump, alternator and power steering pump pulleys all look a bit worse for wear really on this engine so I'll be using the parts from the convertible.
Rusty pulleys.
Pipework & dissy cap. Pipework is simple enough to remove and so is the dissy cap, unless of course one of the bolts is rusted so much that not even Irwin bolt removers will do anything for it. I needed to get the dissy off so ended up having to snap the dissy casing at one of the bolts. I will drill/cut the bolt out later now the engine is out and I have space to do so. You can see the stub of the dissy cap that is left in the below pics.
No dissy.
No dissy, no air.
Alternator. Rust...everywhere. Right this was more than a little irritating, went to undo one of the bolts that holds the tensioner bar on and the head snapped off the bolt. I should be able to do some cutting and get the damn thing out though which isn't too much of a worry. It does go through the cam belt casing and into the block though which means it'll be a major arse if I can't get it out as I need the alternator to be tensioned. Too late now though it's happened.
No alt.
Power steering pump. Once again, nice and simple. As I'm only removing it from the engine and not the car I just needed to undo a couple of bolts and hang it out of the way.
No pas.
Wiring loom. Various different wires go all over the place and are all attached to one big metal bar just below the inlet plenum. Not too much of an annoyance to remove really but a bit of faff working out how/where to move things around to get them all out of the way.
No loom.
Exhaust, prop and gearbox mounts. With the nose in the air I could then remove the exhaust down pipe from the manifold and then the gearbox mounting bolts too. The exhaust is not great to remove as access is awkward (especially on this Touring as it has been lowered a little) but once the four bolts are undone it comes away nice and easily. There is also a bracket on the gearbox that holds the exhaust, again, couple bolts and it is off. Make sure to do this after the downpipe/manifold bolts.
The prop is simple to undo, three 17mm bolts hold the prop to the 'box, undo them, no need to try and shift the prop back, once the engine is moved forwards a little it'll come off easily.
The gearbox mounts are very simple to remove, few bolts and the mounts are off, few more and the mount frame is off too.
Gearbox without mounts.
Engine mounts/removal. When I removed the convertible's engine I removed the inlet, this was due to the fact I wanted to know what had gone on with the engine, I did not need to remove it though to get the engine out, so on the touring I've left it on.
The rear engine hoist point is right down the back of the engine by the gearbox, not easy to see but it is there, big fat ring. The front one is nice and obvious above the cam shaft pulley.
I connected up the crane, took off the slack (lifted the front of the car slightly with the use of the crane) and then removed the engine mounts at the car side. Once the nut on each mount was off I then removed the four bolts on each mount that secure it to the engine. I was aiming to do it without removing the mounts but it didn't want to come free and in all honesty isn't an issue really.
Engine was free floating now so it was a case of using the load leveller to get the front of the engine in the air and the gearbox pointing down then to get the sump up and over the front of the car then levelling it off and getting the gearbox past the front and down onto the floor.
Engine gone.

As I needed to get the engine to the garage I split the gearbox (don't want to use the one from the touring, I expect it has had a hard life) from the engine and loaded the engine onto a garden trolley. I proceeded to take it down the gravel slope into the garage...nearly had it run away from me due to it's weight and momentum it built up. Got it in there though and loaded it onto a dolly so I can move it about and work on it.
i6 powered garden trolley.
Engine about to escape.
Old vs "new".
"new" engine and the car it is going in.
That's all for today, ran out of energy once I'd done all that. Did it all on my own again and to be honest it really isn't a difficult task at all, provided you have the tools which I realise a lot of people don't have an engine crane in their garage.
Tomorrow I plan on checking on some rust on the convertible and cleaning up the engine bay as well as the replacement engine ready for putting them in sometime next week.
As I like to share and use my multiple cameras for things I set up my DSLR so I could take pictures at regular intervals to create a time lapse video. Unfortunately I don't have the gear to make a true time lapse video but I took a fair few shots through the process of removing the engine and compiled them into a video for your enjoyment.
