Engine rebuild and engine bay resto thread - 2240284 '72 CS

Well it’s in with no bone-headed paint damage etc - of course had a few issues to work around, my brother in law barked the commands while I worked the lift. I don’t like it dangling from a chain. Thanks to @jjs2800cs for the engine lift (and many other tools) - thanks Jeff!

A leveler makes it much less stressful-we had to lower the rear a little get in range of the motor mounts, then some grunt work onto the bolts.

Now to start reattaching things and adding oil and spin for pressure etc.

Simply art! Great job Steve, and great photos. Now... did this draw a crowd? Did someone call play-by-play? Were there gasps from the on-lookers when the operation looked dicey? ;) Mike

Hah yes the neighbors on either side watched from a safe distance, as well as people walking by stopped in to see if today really was the day. Was kinda comical.

Today I hoisted the engine off the stand and installed the clutch and crank nut. A friend of mine made me a very nice nut lockplate which I installed. Torqued as close to 325 as I could estimate, loctite, and this lockplate ought to hold it securely enough :cool:

The engine goes in tomorrow am! Then a few weeks of attaching the peripherals and show time.

it looks fantastic Steve,
i wonder why don t you install the peripherals before and not after the engine is in the car

i installed all the bits before, except the carbs

did you found difficult to introduce with the anciliaries ? was that the reason ?

I installed the clutch beforehand. I wanted the installation to go as quickly and without incident as possible because it was being done in my driveway-somewhat frowned upon in my neighborhood. Even then I had to remove the pulley from the front crank as it was slowing me down. It’s the double pulley from a later car which allows me to run the ps pump off the crank not the water pump. It protrudes forward quite a bit. Plus I figured fewer ancillaries would mean fewer chances of paint scratches etc.

Today I got the bell housing on, tranny in, shift tower and lever linkage in, driveshaft on, and got the critical flange/guibo connection wobble-free by adjusting the height and side-to-side of the CSB.

Tomorrow is test fitting the headers then they go to the ceramic coater.

No pics because I am too friggin’ tired :cool:

I added oil and spun the engine to check for pressure. I’m getting 25 lbs while cranking, I installed the 850i v12 sr-444x starter and it sounds like an F-16 firing up - love the sound. So all good there.

Headers are off to the ceramic coater, I test fitted them and no bending was necessary, only about an inch trimmed off the length. I’m glad I went through this exercise because there is a process to getting the headers in place without banging them on each other or the block, this should help when installing when they’re finished. The method I came up with is:

-Protect everything with towels
-Steering all the way to the left
-Lay front pipes in and rest on subframe
-Install rear pipes loose on studs
-Place front pipes on studs and tighten
-Tighten rear pipes on studs

So hopefully this will minimize damage on install.

While waiting for them, I am attaching peripherals. AC compressor is on one of Layne’s brackets which is great. Since I am using the flexible reduced barrier hoses, I routed them under the frame rail and though the front clip to clean up the fender area. I also installed all the hoses and fitting connections for the entire system so it’s ready for vacuum test:

Next I had to get the PS pump to line up with the later model crank pulley (I’m not using the stock system of driving it off the water pump). So I made 3 stand-offs out of 8mm ID x 16mm OD aluminum pipe to extend the pump on the existing brackets (I never could track down the later model brackets to do this), 2 are 18mm and one is 19mm in length. The 19mm is a little longer in order to tilt the pulley on plane with the crank.

Alternator is cleaned up and installed also. It takes a lot of time to do these because I am making changes/improvements to wiring etc as I go.

I know you’ve been working, i’m tired just reading this. That’s a lot to get done!
 
Big day today, the carburetors went on sans airbox/filter assembly which will go on when I have a tuned running engine. The only thing left to do before ignition launchpad firing test is to get the header back on from the ceramic place. Hopefully this week. All fluids, pumps, hoses etc all on.

On a side note, I am very disappointed in the quality/fitment/choice of materials for the W&N/BMW firewall insulation piece. These things are bloody expensive and they don’t fit well, and scratch if you look at it the wrong way. I had to cut various sections in order to fit as well as reinforce the back for fear of it tearing. Why did they choose such a fragile material?

Anyway, some engine porn:

Please don't run the engine without some sort of screens/filter. Isn't that how this whole thing started? :D
Kidding, of course. It is looking so great!

Wow Steve - looks great. Which water pump pulley did you end up with?
 
Steve--All looks nice. The upper firewall insulation will hardly be noticed once the engine bay is completed. But, indeed, the harshest critic is always the owner.

I installed the 102mm one for starters, this will clock the water pump significantly at low rpm. I also have a 130mm one to use if for some reason I don’t like the smaller one. Both smaller than my original one.
