I replaced all 6 injectors on my wife's 05 Mercury Mariner (3.0 V6). After doing so there was a fair amount of white smoke coming out the tail pipe. Filled my garage. After a little bit it was less and less, and eventually none. The vehicle runs great, no issues at all. All fluid levels are where they should be, everything is connected properly, and they are just a stock replacement injector. Nothing performance, they are Motocraft injectors as well. I'm assuming there was some type of lubricant or preservative (mmmmmm preservative) in the injectors and it's just that burning off, I've just never seen that before. Anyone have any experience with a situation like this?

it doesn't take much with heavy petroleum distillates that are used to keep the injector internals from corroding

if a can of seafoam can keep a heap vaping for an hour....a teaspoon can do it for a few minutes.

12 drops of oil on the exhaust manifolds will do nearly the same thing

You should see what it looks like when we do heads on a Chevy truck and a shot glass worth of coolant spills into the exhaust. It's like fogging for mosquitos for an hour

you should see it when an EGR cooler blows and dumps 2 gallons of coolant in the cat and another 2-3 in the muffler

I didnt know egr coolers existed. Are exhaust gasses that much hotter with a large diesel engine? Or is it because of heat soak?
EGR coolers have been around since about 04. With all the tighter emissions, the diesel world needed an answer and early on it was band aided with HEAVY amounts of EGR. So much that it had to be cooled down before it was shoved back into the intake. We're talking on average EGTs around 900°+^. Later systems incorporated dual EGR coolers to alleviate some stress off of just one cooler. Then we cut back quite a bit on EGR thanks in part to DPF/SCR/DEF. Now we're just changing coolers mostly due to clogging thanks in part to ignorant drivers.

Def is awesome. It allows us to ramp up Timing to increase HP.

On big equipment thy fight a thing called wet stacking. It's basically when an engine idles all day, the layer that builds on top the piston is actually wet. Them after hours of idle they open her up and boom there goes the cylinder

Non VGT, non dpf trucks need not to worry much about short trips. It will just have alot of moisture in the oil like any other type of engine that sees short trips and isn't at full op temp for a bit.
