Lifted E30 V2

[GunMetalGrey]

So I was really hoping to post some sweet pictures of this thing out in the insane snow storm we got this weekend, but apparently that was too much to ask for. 
Got it running but something wasn't right, it would change revs on its own, there was a lot of air moving through the fuel system even though there was no air being pulled into the pump, and things in general were just being odd. at some point it was realized there was fuel dripping out of a banjo bolt that was open, as I believed it had been on the old one. I double checked for sanity and found that the old one indeed never had that port plugged or plumbed, as I thought it was a vent port. 
Well it is, and it should never have diesel seeping out there. Here is a nifty cutaway to show you what port. (10)

That area shouldn't really have much fuel in it to begin with, and it certainly shouldn't have fuel on the underside of the boost compensation diaphragm. 

Pump is coming out and going to the diesel shop that did my injectors, along with the parts pile that is my old pump. I hope to sweet baby jesus that they can make the "new" one work with either purchased parts or ideally parts from my old pump.

Can this just work please?

What a headache. One more piece to this jigsaw of a fuel system.....

Oh, I also still had coolant leaking from the floor/frame rail. 
If it's the heater valve I may just roll the car outside and throw a match in it.

Dropped the fuel pump off at the diesel shop today. 
I told him what was going on and he immediately had an assumption of what was wrong, and figured it was just an o -ring inside the pump. So that's cool to hear.

I asked him to do what he needed to do to make it work, and test it, so that when I put it in the car I know it will work.

[GunMetalGrey]

I should have known this would happen, but guys, for real. Avoid diesel BMW stuff at any cost.
Repairing and testing the pump cost more than the pump itself.
 
I have an $1,100 fuel pump, and it doesn't even look that cool.

You can replace the heater valve with a  bit of hose and a brass valve for cheap, or, disassemble the leaking one, remove the actuator, and cap it with a block off plate which will leave it always open.

I like the brass valve idea lol. Valve open in winter, valve closed in summer.

mostly yes, but, dont forget the windshield can fog to hell on a summer day in the rain. without the heat, its hard to get rid of that condensation.  i did a couple of autox runs in the rain with my windows wide open so the windshield would stay clear when i bypassed my heater valve last year.

Did you get the pump in this yet? I was driving near Oshkosh this past weekend and saw a massive plume of black smoke in the skies overhead figured it might be you ripping around...

[HipMF]

This past weekend I tried to get a video of the sweet smoke-rings that this thing blows. There was a lot of smoke, but no smoke-rings. Troubleshooting that I saw involved re-bleeding the fuel system and not much else. Waiting on the sage wisdom of a diesel elder...

18 days and 14 hours remaining until e30 picnic begins...

Quoting for proof. Although I think I'm siding with you on this one.

Got to see this beast in person over the weekend! Unfortunatly it was static

[GunMetalGrey]

The lack of confidence is saddening really. 
My lack of time to work on it isn't great, but I have an action plan, and it all involves the Friday evening before the picnic, as that is my first available time.

Dont let the nay sayers get your hopes down. I have faith in you!

[GunMetalGrey]

I have thrown in the white flag. Time to switch back.
Got more air worked out of the system but still doesn't want to idle or run normal, and then will frequently just rev itself up to 4500 or so and just sit there with no throttle input while smoking white (blue?) a whole bunch. 
Either the motor is toast or the pump isn't working right, with my suspicion more toward the pump.
