Iím a new member and just got into the Volkswagen world with the purchase of a 1982 diesel rabbit. The reason Iím posting today is that even though the engine in this rabbit has under 10k miles on it, when I start it cold (around 40 degrees not arctic temps) it starts spewing white smoke about 10 seconds after it gets turning. (See the attached video). The engine runs really rough and doesnít stop smoking if let idle. It takes giving the engine Gas and smoking out the neighborhood before I can get it to idle right and stop.
This is how far Iíve got on testing attempted fixes:
-Replaced all fuel lines in the engine bay with clear lines (no bubbles seen on feed or return when left for days without starting, prime holds fine)
-Replaced glow plugs with matched Bosch plugs and replaced glow plug bus bar with 10 gauge wire, checked all plug currents with a DC current clamp to ensure they were all drawing the specified amperage.
-Pulled the injectors and pop tested them. All were within pressure spec and didnít leak but some showed pitting around the nozzle.
The next step is to check compression but before I head out to spend more money on a tester I wanted to see if anyone has some ideas to chime in. Perhaps thereís something I have missed? I wonít rule out a head gasket issue but it seems unlikely due to the low miles on the engine.
Thanks for any help you can give.
