VW ALH TDI injection pump head plug seal replacement

Well, I had a fuel leak coming from the head plug seal on the injection pump on my 2001 Volkswagen Golf TDI. Originally, I thought that the leak was coming from the head seal, but that wasn't the case. After further diagnosing, I then purchased a head plug seal kit from Diesel Geek that included a new seal and special 24mm (15/16") modified socket to fit the triangular head of the plug. You can modify a 15/16 or 24mm socket yourself if you want, but I chose to borrow the one from Diesel Geek. All you need to do is send it back when you're done.....it's that simple. I hope that you enjoy this video. Thanks for watching!

As you know I just replaced the bigger head seal. Today I noticed this seal leaking also. I was very relieved to find another video of you covering this. In hindsight I should have done this 30mm seal at the same time. Thank you again for these videos, they are of great help.

Hello sir only big bolt open and seal change? For leaking same type

Yes, there's just one seal around this plug. It's a pretty simple replacement.

Hello! A friend of mine removed the pump from the engine to change this exact seal. Changed the seal, put the pump back on the engine but messed up when plugging up the electrical connections. He switched the small plug from the injection pump with the one from the crankshaft sensor, they both look the same and fit. Now the engine won't start and won't run unless it's on strarting fluid. Did he fry the electronic part of the injection pump by plugging those two connectors the wrong way?

@Corysdiyauto Жыл бұрын

Ooo no. Sorry to hear about your friend's luck. Is he sure that he bled all of the air out of the system? I would tell him to crack each line at the injectors and crank until fuel comes out of each line. It would be a good idea for you to help him do that. Have rags ready and be careful.

@@Corysdiyauto Yes, we have bled it countless times, we even fed it straight from a bottle, bypassing the fuel filter. Started the engine on starting fluid, ran it half a minute like that, nothing. The pump was taken off the car. Thank you for your answear.

does a 26mm injection pump socket fit? or only 24mm every socket set i find is 26mm only diesel geek has the 24mm that you have to rent? makes no sense

@Corysdiyauto Жыл бұрын

It's a 24mm socket. I have the info in the description. You can make your own by modifying a 15/16" socket.

hi, why do you have to put those red caps on the outputs?

Did you have to time the pump by removing the 12mm like you did on the pump head video before removing the plug ? I’ve found your videos extremely helpful while working on my own Alh

@Corysdiyauto Жыл бұрын

You don't have to do anything to the pump. All you have to do is remove the plug and replace the seal. It's actually pretty simple.

The head plug seal was leaking in my case. I replaced the injection pump head seal first though because it looked like the fuel was leaking from that area.

I called VW in Germany and got the torque spec from them. They said to tighten it down until it's "gudentait". Must be a metric unit but i did "Nazi" that one coming.
