He didn't update it lately but took it to D4C 2016, there are some photos on the website showing it. Actually somebody stole 2 of his spark plug wires and he left the car out there until a month later when he could pick it up and drive it home!
Thanks for the link. Sucks about the plug wire theft. That's a pretty silly thing to take from someone.

That's something new. Someone stole 2 spark plug wires? Geez, I can't figure what people are thinking.

I imagine some old bimmer with lots of differed maintenance braking down some where near where the car was sitting and the owner of broken down car helping himself to what he needed to get home, or just kids playing a "joke" Either way must have been annoying.

Pics of my E23 735. I did the timing with a Snap-on digital timing light. 33 degrees @1800 RPM.
I adjusted mine by hand yesterday and it appears pretty close to this. Haven't done it with a light yet though.

Also for reference, I used the L-block head gasket BMW 11-12-1-730-951, elring #772.992. I got from blunttech.com and have to provide my title to get one ordered. They will not allow you to buy 2...

Another hold up from driving the car...

After putting a few hundred miles on it, I noticed this strange sound with the clutch.

Some suggest throwout bearing. Other ideas?

Input shaft bearing? Just throwing the suggestion out there. Throw out bearing seems more likely.

As an update,

I'm currently in process of removing the transmission from the car. I dropped everything from underneath and have the transmission tilted but need to continue removing it by separating the engine from the trans at the bellhousing or the bellhousing from the body of transmission (G265 dogleg).

Interestingly, this car has hex bolts holding the two together, so maybe it wasn't until the E28 changeover that they started using TORX bolts. The transmission is greasy so it's a messy job, hope to make a bit of progress this weekend and have the transmission out.

May buy S wrenches to get the last bolt free from the bellhousing and pull that out separately. Not fun, but doing this to replace TO bearing. Will have to see what other parts I'd like to replace since it will be apart ](*,)

Tom, sounds like a lot of fun. I just thought I would mention ( I'm, sure you've read the same stuff I have ) I have usually read that most guys use a bunch of extensions and wobbles etc to attack the infamous top bolt on the bellhousing. It sounds complicated but maybe it works better than S wrenches? IDK as I've never done it myself. Good luck with it.

Both my 77 and 79 have hex head bolts . I think I read somewhere after a couple of years of e28 production they switched to Torxs. Not sure

When you get the tranny out I'd be interested to hear how much the input shaft wiggles back and forth. I have a couple 265/6s ( not installed ) and the input shafts have what I think is a considerable amount of play. Like 1-1.5 mm of wiggle.

I believe the input shaft bearing for the dogleg is easily available and not crazy expensive like the OD trans.

Removal is complete as of this evening! Doing this as a one man job and was having issues getting the 19mm's off the bellhousing of the G265. Well I bought an S wrench from Harbor Freight and was able to file down the edges and get it on the driver's side upper. That was the one I was most worried about anyway.

The work space:

Once that was loose, I was having difficulty getting the passenger side upper nut loose. I ended up using my air tools and my 6 point impact driver to finally get it loose.
After some wrestling, I got it out!
Sliding it off the engine:

The access from underneath once the trans is out of the way

I imagine it won't be as fun to put it back in... it was still really tight to get at the bolts with the bulk of the transmission out of the way!

And here she be. Going to clean it up and start ordering some parts
Image

Dave, the shaft seems to wiggle 1-2mm and comparing to my a 260/5 I have sitting there, they wiggle about the same amount.

The throwout bearing is definitely the problem-- noisy and crusty spinning it by hand. Not sure how it failed, but it happened suddenly as far as I know.

What other parts should I replace while I''m in there? I need a trans mount as well as a new guibo for sure.

I have an extra oil shaft seal, but yours may not be leaking because mine wasn't leaking. I also replaced the guibo on mine. It was in decent shape but had a few cracks so I replaced it since I had the part handy.

So much easier to remove than a one piece box though and not too heavy if you're ready for it. The output has about that much wiggle on both of my boxes - I would think this is normal as the output shaft is not part of the main shaft.

I cleaned the gearbox and got it back together in the last week or so, wrapping up last night.

It took me a couple hours to get the trans into place and then a couple more hours to button it up before spending time wrestling with the full length exhaust.

Unfortunately my rear section of the exhaust was loose, so I have to see if I can get it welded back into place maybe. i really liked the sound of it and it came apart because of the on and off I have to do for the repair job.

I also decided to mount my Rial mesh wheels (refinished) since I had tires and hadn't driven the car all year. I think they fit it really well!


16x8 et11 with 225/5016 riken 'Raptor' tires. They seem pretty grippy for the closeout price I got.

I need to double check distributor timing but overall I want to drive it more in 2018!!
