Replaced my injectors today in the 240D (thanks Sean! ). No problems with the install, and it smoothed out the idle and ride....seems like one injector is nailing a bit though?

Anyway, there were no heat shields under the old injectors. I did some searches and all I could find were dire warnings to always replace them. What are the long-term consequences of that?

I guess that may be why I needed them replaced?

If the Ball Pins looked good when you inspected them and the area where the Heat Shields seated was not burned I do not think there would be any problems.

technically the factory manual says to replace the heat sheilds, so...

Sev, he said when he pulled out his Injectors there was no Old Heat Shelds.

I assumed when he put in his Injectors he put in new Heat Shields and I thought He is asking if there could be damage that will show up later because it had previously been run without Heat Shields.

Bingo.

Everything looked pretty good under the old injectors, there was some burned fuel (black and viscous, but smelled like fuel, not engine oil) in 2 of the injector wells, and the old injector tips were pretty blackened, but that may be normal on used injectors - never seen them before. Other then that, the prechambers looked ok - not sure what I would see in a bad one - but they all looked similar and metal colored, and the metal in the injector wells was shiny.

Car has continued to smooth out, and had no smoke on startup this morning at 37* where there used to be smoke on startup everymorning with the old injectors. So, I have no reason to think there is any problem with any of the cylinders, so I will just carry on


Thanks y'all!

EDIT: Wow I just saw Sev was banned....can't say I'm surprised, based on some of his flaming in other threads, but it happened pretty fast!
