2L-T Smoky start

[Funksolid]

My friend has a Prado. 2L-T And bought it with a new/upgraded head.

Brand new injectors and glow plugs. Has some pretty bad white smoke @ startup (5 seconds or so, smoke cloud is about the size of the vehicle), and then run perfect. Good power, MPG ECT clean exhaust...

What could be the issue?



Thank You

My guess it is air in the system. The white smoke is from moisture particles in the air. If it doesnt smell of coolant its almost certainly air leaking in from somewhere.
Look closely around any joints or seals disturbed during the head replacement.

They always get a quick 1/2 second puff of white from a cold combustion chamber.

Water in the fuel or low quality diesel? Not sure if Prados have water traps in the fuel lines, but might be something in there if they do...

Is your friend running bio? Often even B5 has a higher moisture level than regular diesel and in winter it becomes more noticeable with cold starts.

Nope the smoke is consistent, and he has bought Diesel from multiple places. And also ran Stanadyne for a few weeks. And no Bio diesel, just the straight stuff.

I'm gonna look into the Air idea.
