Smoke screen

Hi all, problems with my 7.3l n/a. She wont pass E-Test. 3 years ago it passed like wasn't even running, its gone less then 200 miles since but now the guy wont even test it.It smokes hard.
A little bit of a hard start, idles and runs fine, no smoke.
If you snap the throttle white smoke, longer the snap, more smoke.
If you hold it to the hardwood, it'll put you out, smoke screen, 'White smoke everywhere.
The E-test guy said advance the pump, any ideas?????????

Advanced pump is a likely culprit that is somewhat easy to fix.

That or you MIGHT have a cavitation problem which the 7.3 IDI is known for unfortunately.

Does it "use" coolant while its running? You can learn on a few good websites how to fix this with relatively inexpensive tools. If not take it to a guy who knows what an IDI is. Most newer guys have NO idea how to fix on these rigs without a computer.

If you need more help just ask.....I might be able to guide you to those can are great with these rigs.

Agreed, coolant will be the key to it. If its using coolant, has coolant in the oil, or oil in the coolant, something pretty bad is wrong. From bad head gaskets, bad oil cooler, or cavitation.

If its not using coolant, then your trucks timing is running retarted. You have to loosen the three bolts on the IP (the ones holding the IP to the cover, the one on the bottom is the hardest). And rotate the pump towards the passenger side. A little bit goes a long way. Most recommend going less than a dimes width at a time. That should help with the white smoke if it isnt coolant.

Nope, sure isn't coolant, it's diesel all the way.
As soon as the truck is started cold. no smoke. Makes me think advancing the pump is the trick since the cold start advance is on.
Any ideas if the cold start advance serves the same purpose as mechanically advancing the pump?
Just to check and see if pump timing is the issue. Its a van so getting to the back of the pump is a real sweetheart.
