Re: [MBZ] Knock slosh
lines are new and dry. The leak is at the junction, no fluid above there leaking down. I have made sure the hard lines are tight to torque. Did a almost there, loosen, take it to torque, back off, to torque again procedure. No leaks out the tops. If the heat shields need to come out every time the injectors come out, I will order some and get the leak in the body dealt with too. Will I need to redo the calibration for pop? clay On Sep 21, 2009, at 6:07 PM, Peter Frederick wrote: You really should replace the heat shields.

Even a trace of shop cloth lint will make them leak, and that also means they open late from low pressure, and it will knock like crazy. Verify that it's the actual injector leaking, and not the overflow lines, too.

Calibration is set by internal shims, so it wills stay the same unless there is a huge chunk of crud. If you have the old style seals, they can be a real pain to remove.

[MBZ] Knock slosh
Got the injectors installed and Gump starts and runs with more power than I recall her ever having. Problem is that the injectors are leaking at the body and I have a pretty severe knock coming on. I did not replace the spacer in each cylinder, just left what was there in. I think they are all the same anyway. I guess I need to remove and retorque the injectors to deal with the leaking fuel, but what else should I be doing? clay ___ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

Re: [MBZ] Knock slosh
Do you have the hard return lines on that engine? Those are a collar type fitting held down with a nut. They can be buggers to get sealed. You can try loosening the banjo bolt where the collar meets the hard line. that allows some flexibility. Peter is right, of course about the body seal and the crush washer/heat shield between the tip and the prechamber. Those have to be replaces each time the injector nozzle holder is removed.
