QUICK HELP stranded white smoke

[colinmitchell111]

I'm pulled over in a parking lot. Truck running perfect at a stop light started blowing tons of white smoke parked and shut off within 30 seconds. No puking and it did not over heat. I removed the degas cap and there wasn't a crazy amount of pressure. The level went from halfway between the lines to almost max when I relived the pressure. No check engine light. Started back up with cap on and tons of smoke and shut it off. Started and sounded perfect. I checked my deltas a week ago and were within 5. What happened? I am 20 miles from home should I drive?

If it's still running good I'd have to assume the EGR cooler blew. A EGR cooler will still rupture even with good deltas.

If you absolutely have to drive it I'd unplug the EGR valve. This way it will limit the amount of possible coolant that might get into the intake.

If it's smoking real bad though then the EGR cooler must be leaking bad. If that's the case I probably wouldn't drive it. If you do drive it be very careful not to let it get hot.

Sounds like EGR Cooler, EGR Valve problem.

I was assuming egr cooler. I don't want to damage anything further. I just want to get home. With an unplugged egr valve will it not smoke as much or overheat. I only have the factory gauge to go by.

If you unplug the EGR it should stop smoking. Watch the temps and dont boost to hard or it may force the egr open (dont know how just repeating somthing I read). You should be able to limp it home.

Ok just unplugged the egr and let it idle for 30 seconds. The smoking didn't slow down nor did I get a check engine light

You need to unplug the EGR valve with the motor off.

[colinmitchell111]

It was off. Should I try starting again?

If you have tools pull the egr to make sure its closed. if not i'd tow it.

[colinmitchell111]

I have tools. How can I tell if its closed?
