John, I'm off Spring Road in Smyrna. I'm going to try and get to some of these 2002 meetups when I have a chance!

I've been surfing around trying to find a replacement linkage to the rod end from the pump to the throttle on the throttle side and am not having much luck. Any suggestions? Below is a picture of the broken one.

I think you can get that linkage from BMW. Also may try

UPDATE- Got the new linkage rod ends, talk about an improvement!

Got the Tii manual for the KF pump from the TII register. Followed instructions on setting all linkages and adjustments to a baseline except for the part with a CO meter for setting mixture. Prior to that I had cleaned the throttle body, soaked the injectors in chem-dip, and replaced the fuel injection hoses all except for number 1.

I received a fuel injection hose for cylinder 1 from bmw that looks nothing like the oem hose. It is black, flexible, and resembles a flexible hose you would find on the brakes... I don't like the look and want to find a new replacement hose that is identical to the original... Once that is sorted I am most likely going to sell the old hoses here if anyone wants them.

Anyhow after all the adjustments the car starts up and idles fine at around 1000 rpm. No misfire or rough idle and more importantly no fuel leak. I am sure the fuel leak was from the hoses to the number 2 and 3 fuel injectors. Those hoses weren't even finger tight....

Now I have oil smoking from cylinder 3 exhaust header/stud or studs....Not looking forward to fixing that.. I have replacement gaskets but I really don't want to tackle replacing the studs themselves.

The other minor issue now seems to be somwhat slow throttle response. I think there is still some slop in the throttle linkages and I am going to change out all of the old ball rod ends and am considering ordering new springs as well.

From here I am also going to continue to get the car to baseline by checking valve clearances, change points, condenser, and set timing... All things I have never done before.

Congrats on the work done so far. I was in your position when I bought my tii - no experience.

I understand that the black (non-original) line to the # 1 injector is what you will get from BMW -should work I guess. There is a potential group buy of some newer hoses here on the FAQ.

The exhaust manifold studs are pretty easy to replace. Just have to remember to keep everything clean when you thread the new ones in (using Loctite).

Anybody know what type of exhaust this is? Should I go back to stock?

[dubois]

thanks your your kindness and consideration of posting updates as you get closer to a solution here. This will be of great benefit to someone else in the future. Great job!

I was able to get some work done.. I reposted my question regarding the exhaust type. The answers I get are "bundle of snakes" and "spaghetti", ANSA copied from Alpina. I decided to fix my oil leaking exhaust stud and that would require detaching the exhaust manifold. While there I figured I would replace all gaskets and studs.

After soaking the exhaust studs and bolts for a couple days everything came apart very easily. One stud broke at the nut very easily and 2 nuts came out with the stud attached. All of the studs and bolts came out very easily on the top. All of the bottom ones were the trouble makers. I used the "double nut" technique to remove all studs including the one that sheared, which fortunately had enough exposed thread to work with. Pics Attached.

On order are 8 studs, nuts, gaskets, and high temp loctite. I was unable to order everything from one source...

After detaching the exhuast manifold I noticed the number one header moved independently from the others somewhat. On investigating I found a tear in the piping at a bend... I was planning ultimately to go all stock so I guess I am going to replace the exhaust manifold and whatever else needs to be replaced, sooner than later.... Anyone have a line on a good used 1974 tii exhaust manifold or reasonably priced new one? And is anyone interested in my busted "bag of snakes"?

While I sort the exhaust stuff out and wait for parts I am going to finally adjust valve clearances!

[pilotnbr1]

For anyone following this thread I have quite a few UPDATES- First new manifold and downpipe were successfully installed on new studs! Valve clearances were set and car engine runs great! A little greyish smoke on hard acceleration though and smells like its rich. Going to look at the plugs.

Right now I am in the process of repairing the brake system. New calipers and pads on the front and back with new servos on the rear drums. 6 new flexible hoses all around. I found on the right rear drum the piston was leaking brake fluid all over the pads. The old ones literally fell apart when being removed (had two forward sticky adjusters on each side respectively). I also broke an old brake line on the left rear. Waiting for lines to come...

Other issues discovered are the prop shaft center bearing rubber is completely shot. New center bearing and guibo on order. Not looking forward to taking the prop shaft out and apart... Today am going to put in a new fuel expansion tank which the PO owner had removed and lost. And reinstall fuel filter beside radiator... Right now the fuel filter is in the trunk attached on the top of the tank. Also have to troubleshoot why aftermarket electric fan is not coming on when temp goes up...

Down the road new trunk seal and windshield gasket are going on and am putting the original airbox back on.

Question- The fuel tank was boiled out but that was it. I know it needs protective paint on the outside but what would you guys do on the inside? I am thinking of sealing it. The outside looks kinda "scaly" and I know the guys working on it before said they went through a couple electric fuel pumps until they put the fuel filter in before the electric pump. Seems a pretty strong indicator of particles loose inside the tank... Its half full of 3 month old gas now and havent looked inside. Contemplating draining and taking a look....
