Hey all,
This is my first post on this forum, and I hope to learn a lot about diesels from this site. This will be a long first post.
Vehicle: 86 Chevrolet cutaway van, automatic, ~70k miles on original engine.
History: I came across this vehicle through a trade. The owner bought it as a used ice cream truck. The original owners sold because they were told it needed an I/P because of massive leak. The vehicle has set for 2 years. Upon completing my trade, I pulled the pump and found that the advance cam (I guess, the arm on the passenger side of the pump) had worked itself free and the piston that it controls had fallen out ( this would be on the passenger side bottom of the pump). I put everything back together and installed the pump, lining up the stamped timing marks. No leaks and started up.
Additional things done recently: I have replace all rubber fuel lines between the tank and the engine. I replaced the fuel lift pump, and the box fuel filter ( it's the only one on the vehicle). Dropped the fuel tank and cleaned. Removed and checked all glow plugs. Checked for air in lines with clear hose on IP.
Problems History: NOTE: the following is all stationary work done, in the backyard, not moving vehicle from where it set for 2 years:
After getting the vehicle to run, I noticed that it would choke and die. After letting it run for a bit, and eventually adjusting the idle a little higher, this problem has disappeared ( I turned the base idle screw ~3 turns. Haven't adjusted back down yet.)
I thought all was well until I noticed that upon cold start up a large plume of blue/grey smoke comes out(strong diesel smell), as tall and wide as the truck itself. It immediately goes away and only a very faint blue/grey is noticed during warm up. I figured that was "ok" and not a big concern. The idle also lopes intermittently with the vehicle parked and running warm.
After checking all of the fluids and kicking the tires it was time to drive it home.
Road trip: I pull through the neighborhood and notice a small trail of blue/grey smoke following me. I assumed no big deal, just make it home and start tinkering. Once I pulled out on a main street and gave it moderate gas, it starts bellowing smoke out the back, like a comtrail, spyhunter deal.
I was concerned I would cause an accident, so pulled over and called a diesel friend of mine. He told me to put some diesel cleaner through the tank because one/more of the injectors is hanging open. Basic advice boiled down to drive it until it cleared up. I would if it is wasn't such a ridiculous about of smoke. Anyway I drive it home, the smoke seems to have dissipated along the way, and the cold start this morning didn't produce a mushroom cloud.
My question is: Upon installing the pump to the drive gear, with the drive gear loose, is it possible to bump the timing over a tooth accidentally or is there not enough clearance in the timing cover to allow the sprocket to jump over.
Any thoughts, and thanks for reading such a long post.
