If you haven't double-checked the valves, I would absolutely do so.

I think some fuel is leaking around one of the fuel injectors. It is always wet and moist after the engine has been running. I've heard that those collar nuts can sometimes loosen up and cause fuel leaks, but its not likely because they are torqued to something like 120ft lbs. And the tool to tighten them cost about 80$. That is probably the only fuel leak that I know of.

You did not mention how you turned the Engine. If the Engine was turned backwards it claimed is possible to jump a tooth on the Timing Chain. I did not catch what Engine or Vehicle you have but the non-turbo 617 and 616 Engines do not have the ratchet inside of the Timing Chain Tensioner and it is easier for them to jump a tooth. Try lining up the Camshaft Timing Marks with the Bearing Tower timing mark and see what degrees the Pointer points at. And, while the Valve Cover is off recheck your Valve adjustments. When I had clouds of white smoke it was when I installed and managed to time My Volvo Fuel Injection Pump extremely late.

Ill check the valves one more time today and I'll try to check out the timing.

Recapping what you have posted...
YOU did nothing to the motor other than setting the valves. Motor was running good before and isnt now. Gotta repeat... get a fresh set of eyes on the issue. Something very simple is being overlooked.

The motor wasn't running perfect, still started up kind of rough, I assumed it was a glow plug issue, but it ran alright. Now it misses a lot

Ok, I stand corrected.
However, white, black, blue or any other color other than invisible is a combustion issue. Valves are the core of combustion. If the motor wasnt reversed, if the new glow plugs are fully seated and tight, if all your injector lines are tight, what is left ? Valve adjustment. Pls note most diesels run on a ~20:1 ratio. Things need to be nice and snug to achieve that level of compression.

I am not sure how or what occured but you might check the injection pump timing. Just a check is not a big job. The engine could run like this if it were way off. See the archives for how. I doubt this is the issue but I would want to know it is not.

Is it possible that any of your injector heat shields flipped over when you installed them?
Is the smoke blinding acrid smoke or sweet humid smoke? Pull off your radiator cap and look for oil. When you pull your valve cover, look for water droplets. Phil Forrest

Could someone post the thread for the injection pump timing if you find it? And Phil, are you suggesting maybe bad head gasket? I haven't noticed any oil or coolant where it's not supposed to be. And I made sure to put the heat shields in the right way in the injector holes. I was almost sure that the heat shields were the problem because #4 injector didn't even have a heat shield in the first place! By no, stil runs the same

David, Read what whunter wrote. Great advice here. First stop. Take a breath. Relax, and feel confident that what ever it is you will get to the bottom of it.
You posted the Compression numbers in your other thread: (I've made new threads too, at times because it seemed, best to headline with the current issue) but if you do so, you need to provide details. "#1 360 #2 350 #3 320 #4 310 and number five was about 295. The engine was cold when I did the test." You've also mentioned a "wet" injector, is it also injector number 4? If it is wet, try to isolate where the leak is. Dry it, totally, use rubbing alcohol to totally dry the injector, line, line cap nuts, all of it. Other things will work to, but rubbing alcohol is cheap and always in most houses, is a good degreaser, and dries fast. When it's totally dry, have a friend start (or try to start) the engine as you watch that injector, isolate where the fuel is coming from. Pump timing is one thing to look at, but it's important to first address what's wrong, or what changed between when it was running OK, but not great to running really crappy. If the pump timing was knocked off, it would be important to know HOW that happened, and address that root cause. Is it possible injector number 4 has 2 heat shields in it now? That one was stuck in the bore or stuck to the injector? |

How many people have watched the video he posted? Something doesn't sound right with that engine when I listen to it. Seems like it has a metallic sound in the upper end. Can anyone identify that? The smoke does not look like coolant to me. It's unburned diesel I think.
