560SL - Installing CIS Fuel Injectors, Injector Seals & Insulating Sleeves

[@johnpearson492]

Thanks for the video, I've just done this today. I found it was easier to slide the seals onto the injectors first rather than setting them on top of the holders then inserting the injectors. Awesome video!

@@johnpearson492 good idea. I appreciate you sharing that method. I probably should have tried it that way as well. What engine are you working on?

[@johnpearson492]

@TonyLiveTV Same as you and M117 in a 1986 560SL. I've been having hard starting problems that I suspect are from bad injectors but could also be from the leaking fuel pump that I am in the process of replacing as well.

@ hard starting, cold start, hot start. I hear this all the time. After fixing the leak, test the pressures and make sure it holds (see manual), and that should help you identify where the problem is. If your injectors are leaking I don’t think that would cause a hard start. I realize a leaking injector is dry, but all the fuel and pressure is at the fuel distributor waiting for the sensor plate to tell it to release fuel (vacuum moves plate if not stepping on pedal). The injectors fire off around 55-60 psi or something like that and it only takes a split second for your dual pumps to do that. I think a bad injector symptom would be different like a ruff idle, poor gas mileage and stuff like that. On the other hand, if the injector doesn’t fire (clogged or stuck rather than leaking), you would have more problems than starting. Electrical can cause hard starting too. You go over the ignition part of things with a multimeter for free! Let me know what you find. I am interested to know what you find.

Really need to test or replace mine. Just a bit more difficult with the engine in. Very satisfying “pop” when they seat!

Thank you!

such satisfying clicks from the injector cups!!! Makes me want to go reinstall mine as I didn't get such satisfaction. :-)

It was super nice to hear those pops! I think the reason is because I was using those rubber plugs on the top of the sleeves. I believe the rubber plugs sealed the injector tube so it compressed the air which eventually escaped and made the pops.

The editing and video quality is on point 🎯

Thank you.

Love your work and knowledge man! I’ve got a 450SL 74’ and one of my fuel injector holders bolt was stripped by the mechanic I took it to and he tried to fix it by boring a new hole and threads and put a new bolt in with some type of glue he said. Over $400 later and a stripped bolt. Still over heating and running worse than before I brought it to him. He specializes in German cars. His whole shop does. Anywho. The driveshaft join underneath the center “console” down from the shifter knob under the flat area. Sound like it’s loose or something. It wasn’t like that before I took it to him. I regret wasting my money and not just figuring it out myself and not breaking things and making it run worse.

Have you seen my video titled “The Incompetent Machinist”? He is a 38 year self employed machinist and everything he did for me was crap! kzbin.info/www/bejne/qoSzZIB_l7iLnqc Also see the video “Deburring The Cylinder Head” which is me repairing the machinist’s work. kzbin.info/www/bejne/l53ZYp-AgMlghJo

Hi Tony, why not do alive Q&A session or just a chat session for a few minutes to do a test for the live start.

[@TonyLiveTV]

Sounds good to me!
