New M998 Owner - White-Blue Smoke

[TOBASH]

Don't start in the garage. Too cliched. If something happens people will look for years for your note about why you did it.

Seriously, it will stink and it is dangerous.

Best,

Ok, I just had the cold advance sensor replaced. This WASN'T easy! It was fused. Had to soak in PB Blaster then use a blowtorch. New one is now installed. It seems to have helped but I'll know for sure when I start it in the garage.

Here's the only troubling result - of course, the coolant leaked out (at least 80% of it) and it looked like redish chocolate milk. The color of Alabama clay. Yes, it probably had the orange coolant in it, but that had some rust no doubt. So thursday, I am having the system throroughly flushed with a hose then the coolant replaced.

I also changed the oil and filter, using the Shell oil and Delco replacement filter. Again, the odd part was that a day after the oil was replaced, it turned black - without starting the truck! I replaced the oil and it was amber, then later on that day it already turned coal black without starting the truck once. That I suspect indicates lots of residual oil, so I plan on changing it again in the next few days.

Glow plugs are in, so I will be replacing these along with the PCV this weekend. I spent the last weekend repainting the entire truck in Rapco woodlands, and all the grills, bumpers, etc. in satin black. I also replaced all the hardware and all the lights, reflectors and side markers. Still have to replace the doors, interior insulation, gauges, windshields and gaskets. Fuel filler surround and a few other parts are on the way also.

I'll post pics soon. Again, thanks to you all for the help!

diesel oil is charcoal black after running, this is normal....that’s why you use an oil made for diesel engines, it has a detergent in it. Plus you can never get what is in the cooler out. Change and leave it.

lol I meant once I start it to back it out of the garage.

OK, quick update on the blue smoke thing.

I replaced the cold advance valve (mentioned above) and now the PCV. After driving for a day, the smoke was gone! No more startup smoke. However, just after I told everyone I knew about the fix, the smoke came back last night. Cold start, and there it was.

The smoke is significantly better, but it still smokes a blue smoke upon cold acceleration and some startups. This morning, for example, no smoke. No misfiring.

I'll be installing the glow plugs hopefully this week. I say hopefully because I have been completely restoring the car over the course of 2 weeks, repainting, new hardware, new doors, windshields, lights, interior strip and repaint, etc. It's hard to focus on mechanical when new cosmetic parts arrive!
