Goce Posted October 24, 2020 Report Share Posted October 24, 2020 Too long is years, measured from the air will rust the cylinders and valves Quote Link to comment Share on other sites More sharing options...
Jayden M Posted October 24, 2020 Author Report Share Posted October 24, 2020 ah ok, so I can leave them out for a few weeks to get this fixed. Quote Link to comment Share on other sites More sharing options...
Mike T Posted October 24, 2020 Report Share Posted October 24, 2020 To be safe stuff some oily rags in the holes to keep dirt and insects out. Quote Link to comment Share on other sites More sharing options...
Jayden M Posted October 26, 2020 Author Report Share Posted October 26, 2020 anyone know how the fuel injectors come out of this thing lol? There is a hex nut thing, but i dont know if thats related to holding it in, do I just pull up? Quote Link to comment Share on other sites More sharing options...

Goce Posted October 26, 2020 Report Share Posted October 26, 2020 Great video, i've watched his videos on diesel injectors, there is things to learn from him. Â Quote Link to comment Share on other sites More sharing options...
Bean Posted October 26, 2020 Report Share Posted October 26, 2020 (edited) Oops - just watched it and the MB is held in different. Â They do just pull out but this might be better for removal: Â https://forums.fourtitude.com/showthread.php?3508551-Awesome-Fuel-Injector-Removal-Tool-for-CIS-and-CIS-E!!!!!! The testing and cleaning should be the same however. Â Good info and it does sound like the injectors are crap - Especially the one that filled the cylinder with fuel!

Jayden M Posted October 27, 2020 Author Report Share Posted October 27, 2020 Yeah I didn't get any of the injectors out, but at least I got a workout trying to... those things are in there REAL good. Thanks for the video, I actually learned a lot from it, and from you guys. Quote Link to comment Share on other sites More sharing options...
Goce Posted October 27, 2020 Report Share Posted October 27, 2020 Jay, what progress have you made, did you undo the lines going to them and the retainers, can you rotate them with a wrench? Quote Link to comment Share on other sites More sharing options...
Jayden M Posted October 27, 2020 Author Report Share Posted October 27, 2020 oh, was I supposed to take off the lines from the distributor? Silly me im such a dummy. They rotate easily without wrench Quote Link to comment Share on other sites More sharing options...
Bean Posted October 27, 2020 Report Share Posted October 27, 2020 You need to undo the fuel lines from the injectors before pulling them off, but you shouldn’t have to pull them from the Fuel distributor.  If you pull lines off you should run them into bottles and ensure they all flow fuel and that it’s clean fuel. From memory the injectors aren’t held in with retainers like the Mercedes video - Pull them straight out like the VW article linked after.

Jayden M Posted October 27, 2020 Author Report Share Posted October 27, 2020 Oh ok. Also the link provided didnt take me to a vid/article. Do I need to use the wrench to loosen the hex nut? or does the fuel line come off like a vacuum hose? Quote Link to comment Share on other sites More sharing options...
Goce Posted October 27, 2020 Report Share Posted October 27, 2020 They are high pressure lines so they need a wrench to be taken off maybe two, one to stop the injector from rotating. Â Quote Link to comment Share on other sites More sharing options...
Bean Posted October 27, 2020 Report Share Posted October 27, 2020 I fixed the link. A slide hammer and some ingenuity should work well, but there's lots on line for building DIY cleaning set ups and tools. This one looks like a great way to clean them, but I'd use a syphoning blow gun and some BG44 or Liqui-Moly injector cleaner to blow through until it sprayed nice.

SRDT Posted October 28, 2020 Report Share Posted October 28, 2020 On 10/27/2020 at 7:19 PM, Goce said: They are high pressure lines. Â They looks like it but they aren't, the pressure is quite low compared to a diesel injection pump so they are probably more fragile.

Jayden M Posted November 1, 2020 Author Report Share Posted November 1, 2020 Sigh. In going to have to buy injector removal thing. Tried prying them out with all sorts of stuff, not sure that tool will be any better. Im having just as much trouble simply getting the lines off the injectors...

Bean Posted November 2, 2020 Report Share Posted November 2, 2020 Slide hammer might be best - would need to fabricate an end to either engage the fuel line threads, or a hook to get under the fuel line nut. Rabin Quote Link to comment Share on other sites More sharing options...
Jayden M Posted November 4, 2020 Author Report Share Posted November 4, 2020 I cant even get off the line going to the injectors... I tried twisting them, literally standing on the engine, but they wont budge. Nearly ripped a line. The injectors I think have rusted, and swollen squeezing the lines onto the injectors, and then the fuel lines themselves have probably stiffened, making it even harder to get the lines off. I may have to just focus on taking the injectors out, and then replace both the injectors and the fuel lines.... like jeez. Quote Link to comment Share on other sites More sharing options...
Bean Posted November 4, 2020 Report Share Posted November 4, 2020 You need to use a good penetrating oil like Aerokroil or an ATF/Acetone 50:50 mix. PB Blaster isn't bad in a pinch either - just keep soaking it down as often as you can. I'd also suggest clamping the injectors with vise grips locking them into something solid, some flare nut wrenches on the fitting, and then hitting the wrench with a hammer to free the line nut. Secret will be soaking the injector and the nut down with penetrating oil for at least a couple days. Rabin Quote Link to comment Share on other sites More sharing options...
Jayden M Posted November 4, 2020 Author Report Share Posted November 4, 2020 Alright, I'll soak injectors for a few days before messing with it again. I had sprayed PB blaster a bit before but more couldnt hurt. If that doesnt work, I could drill into the injector, and then use a pry bar, but that is a little excessive haha.

Bean Posted November 4, 2020 Report Share Posted November 4, 2020 Yup - soak the crap out of them. I'd do a slide hammer with a U attachment that hooks just under the line fitting nut. Get the injector out and then worry about removing the fittings from them.

Jayden M Posted November 4, 2020 Author Report Share Posted November 4, 2020 I'll try, but I cant really get under the hex nut on the injector Quote Link to comment Share on other sites More sharing options...
Goce Posted November 4, 2020 Report Share Posted November 4, 2020 Take some pictures, Jay perhaps you can use fork or a crowbar to get behind the the hex on the injector. Quote Link to comment Share on other sites More sharing options...
Jayden M Posted November 4, 2020 Author Report Share Posted November 4, 2020 Got a picture, probably not the best quality, but you can see it goes kinda far, only my screwdriver can get in there, but screwdriver will break if I push any harder.
