Anyone know what to do? I tried a craftsman 21 and 22 but no luck.

I've thought about taking mine out and getting them tested, no particular reason, would just like to know.

How many miles?
Have you been having problems? If so what type issues.
Are you looking to replace/test/rebuild? If so, please keep us informed of results, or manufacturer etc.

Thanks.

Well according to benz bin they wear out at 100K. My engine has been feeling kinda rough so we shall see. They are wrong about the 27mm socket. That will not even work.,

I don't believe what the Benz Bin says is accurate and I think many will tell you the same. Injectors can last indefinitely if the fuel is good, i.e. if you use a good fuel additive as plain diesel fuel is quite crappy, but it's still a good idea to check them every now and then. I checked the ones in my '96 about 6 months ago and they were all fine, even the pop pressures were perfect. I do believe they are original.

Well, it would cost me $50 to find out each time. That is what they charge to test the injectors. And they charged me a little more to disassemble that one bad one they found and clean it up.

5 injectors were at the right pressure, 135 bar and 1 was leaking and had bad spray pattern. Wife reported that the car feels much smoother and "glides" now. Besides, it was time to take the glow plugs out and make sure they are not siezed up.

Thanx to you, I now have the right tool for the right job. It is basically a thin 22mm very deep socket with a part of it gouged out. It was about $20 from the dealerhship.

Thanx for your help

Thanks for the all the info. The more I gather the more comfortable I feel about getting some of this done myself.

raMBow, Without the socket it is not possible to get it done. Several supplies also needed.

1. New hose and terminator for the injectors. Those are the return lines and the last one has nowheres to go so there is a terminator. They are some sort of viton line and the injectors are daisy chained together till the last one. You will see 2 nipples on each injector. Hose comes in 1 metre length and you will have to cut to fit. Hint, wait till you get the injectors screwed in before you do it, Then you can put the fuel line from the IP in. A 605 078 05 81 and 605 070 00 55

2. Plastic clips for the fuel lines. Probably break a few taking it out because it is brittle from the engine heat. A 603 078 01 41 Bracket (Qty 7)

3. O-ring for the EGR to intercooler pipe A 606 997 06 45

4. Injector Seals. Put concave side up as when you remove. A 601 017 00 60 (Qty 6)

5. Intake Manifold Gasket A 606 141 01 80

Lets not forget the magical socket that dieseladdict refers to that I now own. $20 approx.

Go from beneath to get to the hex bolt holding the EGR to the manifold. Take off the middle belly pan as tho you were draining oil.

So... is this the second time you've had a bad injector.

I remember stories that you've had them tested before, and one was bad before. Same one bad? Different one?

I'm still trying to decide where to take mine to be tested. (I figure I need a place to go, before I need 6 injectors in my hand)

I tested them at 100K. I am at 130. I have taken the GPs out a couple times already to make sure of them. the one that was bad was actually dirty so it can be cleaned and made good.
