those oversized vintage-styled wheels on the cobra are fricken amazing.

Tried removing the #6 injector.
27mm deep 1/2 drive with a 2.5 foot breaker bar.
I got concerned as to what was going to give due to the amount of force I was applying, and nothing was moving.Yay stuck things!
Soaked with PB blaster for a few days? The injectors on my truck take a 30mm socket and had a 3ft pipe on a 1/2in Craftsman breaker bar and it still took force to break 'em all loose.

Yeah I hit it with PB. Steel injector bodies in an aluminum head, should be a fun one.
Try to take it out when the engine is at operating temp.
Yeah that may be my next attempt.
Try to temp it when the engine is operating at take out.
I wish I would have thought of that before

It takes a while to realize the possibilities you have once you own a temp gun
But does it?

I had my wheaties for breakfast yesterday.
I really leaned on the breaker bar and it turned about 1/8th of a turn and then got super tight. I rocked it back and forth then pressed on. Eventually it got to the point where I could unscrew the injector by hand.
Caked full of crap, it came out.
What the low pressure return should look like
What the low pressure return did look like
Now to find a "new" injector, or at least the back half.
I took it apart for fun.
Now I need to figure out how/why this engine is leaking so much oil/fluid. This is nuts...
-
Super low RPM "pull" that I forgot to post. This was after turning up the fuel amount, and before adjusting the low boost fuel, smoke that black is going to drive my EGT's up too high! But it looks cool, and that's what it's all about right?
-
OH MAN that injector is junk. LOL
Check this out its filled with info.....
Quoted from a Bosch technical document then quotes from MyE28.com:
These nozzles are known as Delay Pintle Nozzles, and are nearly always used with the Indirect Injection Engine, and have part numbers like, DN0S"D"299A.--The "D" in inverted commas, refers to Delay type nozzle.
"DN" "0" "S" D "299A"
"DN" referrs to Pintle type nozzle
"0" referrs to the spray angle, whether its defined as a number of degrees or not.
"S" refers to the size of nozzle body.
and "299A" refers to specific characteristics of that particular nozzle ( apart from this number its not possible to find the charaterictics of the nozzle from the makers)
Any letters before the "DN" refer to the maker, eg. B, C, K, R, V are all Lucas / Delphi maker codes, Bosch generally use just the basic number.

There is one in Bulgaria on Ebay for $40 if you cant find one. LOL

I've been eyeing the one in bulgaria up for awhile now.
I have spent plenty of time on the diesel section of myE28, and that chart is useful for nozzles, but doesn't have any info on the bodies. Which appears to be a common thing.Going to try the junkyard for some VW injector bodies, they look the exact same.
-
Good call. I would just go pocket some from a salvage yard and compare. They cant be far off, if not the same!

I may have access to a couple hundred gallons of free bio-diesel. I need to get this thing running again! The start of new school semesters is always rough, but this is my last one, so gotta keep the head up!

I'm feeling like this is a wild goose chase to find/figure out how these injector nozzle holder codes work.
What I do know:
KCA30S50 is the nozzle holder for the M21 Turbo
KCA is the style of injector
KCA30S50 holders are impossible to find, and crazy expensive if you do find them ($200+ per holder)What I don't know:
What the rest of the numbers truly mean, I have searched high and low for this info and am not coming up with much
The difference between a KCA30S50 (expensive as shit) and a KCA30S44 (Dirt cheap)There is a diesel shop in Green Bay that I called and the guy seemed confident that he may even have injector bodies on hand, but I will likely be taking the mess of an injector that I have now and heading up there to pick his brain and see if we can get something figured out.
I'm thinking of just welding the low pressure return shut on the #6 injector that was leaking, but since I have taken it apart I want to ensure the pop pressure is the same.I should have known this engine would get expensive lol.
-
Crushed the nipple last night and added a bead of weld to try to keep it shut. The injector didn't want to weld as it is almost not metal anymore. I bled air out of the line for the injector but I didn't prefill the injector so I don't think it will work until I fill the injector. Going to try that tonight.
I was also greeted to a large amount of something on the floor when I walked into the shop.
Looks like the fuel pump was leaking diesel at an alarming rate. So that's cool.
It's never done this before, but I've never had one of the injectors out for so long, so I'm hoping that's related because a pump rebuild is about $800.This thing is testing my patience lol.

it may be worth looking at mercedes diesel parts due to the bosch injection commonalities.
im assuming you know about this thread too

Haha, he's right ya know?
So the issue with using other injectors is that I don't know what the body codes mean. KCA30S50 is what the M21 uses, and most Merc stuff seems to use a KCA30S36.
What is the difference between S50 and S36? Not sure, though I know pressure rating gets involved in there somewhere. It seems BMW uses higher injection pressure than most, which may be a factor.I did just find a guy in New York that has a spare set of Euro injectors that he says are in good shape (waiting on pictures) for $175. So if the picture looks good I'll be buying those and getting them tested, or buying stuff to test them myself (pop tester).
I'm really hoping the leaking fuel pump was a fluke, but it looks like some people add bio diesel to expand seals more and that can help, which I conveniently have free access to biodiesel.
I think I'm going to turn into a parts hoarder with this thing.....
