What About Leaking Injectors??

300tdi, at least two of the injectors are leaking. One is enough that the fuel runs down the side of the engine and starts burning off when the engine gets warm.

I believe it is leaking from the actual body of the injector. So a few questions:
  1. Will a shop be able to refurb such an injector?
  2. Can one or two be replaced, or do all need to be replaced at same time?
  3. What tool do I need to remove the injectors?
  4. What else do I need to know?

If its not the line take them all out and down to diesel fuel injection service on Vancouver Ave. they will test them and tell you if they need to be rebuilt or not. They can rebuild if necessary. Great guys and will get it done right!

That's who I was thinking of going to. Was going to call tomorrow morning.

How do I get injectors out without a specialized puller?

Ben, you'd better get acquainted with the LR Toolbox video channel.
Lots of good info for Tdi owners...

I just used a proper sized wrench on the flat area of the injector, being careful to avoid the spill rail sealing spot. Turned it back and forth and lifted hard with the other hand.

I got the old sealing washers out of the bottom with a long long pick

If 1 is leaking then the others are not far behind. Pull them all and @ minimum get them checked.

Replace the brass washers at the base of the injectors before you spend a bunch of money. I had two leaking recently as you describe and a couple of new washers fixed me up.

Getting them out was easy, I just pulled them by hand.....if you need to twist, just use a wrench and be very careful of the spill rail surface.

A little bump of compressed air will loosen the offending washers.

They are new washers already.
