81 Rabbit #3 line issue
Posted: Mon Oct 24, 2016 11:50 am
Hey, guys!
New guy to the forum here! Let me start of by telling you a little about myself. My name is Nick and I have been around Volkswagens my whole life. (Mostly air cooled) I got the chance to buy my 1981 Rabbit Diesel LS with 80,000 original miles for a great deal and decided to jump on it. I have had the car for about 6-7 months now and haven't had any huge issues with it until now.
Now to the issues. Starting about 3 months ago I have been breaking my #3 injector line. I have replcaced it three times now. The last time it cracked I knew there must be an issue with something. I read that I'm either missing a bolt on the injector pump, 'missing a bracket or a motor mount is bad, as those are the usual suspects. I compared my car with my buddies 80 diesel L and saw that I am, in fact, missing the bolt on the drivers side of the pump under the injector lines and I'm missing the bracket that holds all 4 lines together. I still have the two up top though. That's the first main issue. The second is that I went to put the new line on my car so I could move it out of the driveway while I waited for my new bracket to come in. I put the line on and now when I rev the car it makes a horrendous knocking noise but it sounds fine at idle. I did some research and found out it is a noise called "nailing." Correct me if I'm wrong. Now my question is what would cause this? The only thing I did was replace the number 3 line. Did some dirt get in the line and maybe clog the injector?
Thanks for your help. I look forward to using this forum and connecting with diesel lovers around the world.
