WHITE SMOKE everywhere!
so, i'm finally going to be able to spend some time workin' on my new '85 300TD.
firstly, i'd like to solve whatever's causing all the white smoke to billow out of the exhaust. it happens most whenever she's started and/or cold, obviously increasing with accelerator pressure. and, man, she sounds a little sick...loud clack clack clack. i'm guessing since the smoke's white, it means it's fuel? (also, since she doesn't seem to be burning ANY oil)... would you guess it's a valve issue, or would it most likely have something to do with timing and/or fuel delivery? would love some input.

Its a fuel issue, a glow plug issue, or a lack of compression issue.
On very cold starts I let my car glow three times.

The white smoke is a feature, when some one is tailgating you, floor it, they will back off!

Are you sure this is not a headgasket issue, does the white some smell like fuel or sweet, Anytime i have had an excess fuel issue it has been black smoke.

White smoke is generally steam-related. Steam is generally water related. If it's coming out your exhaust in large amounts...well we'll let you put 2 and 2 together...and it won't be cheap.

Hold up a piece of white paper to the exhaust to capture the smell and color. just my favorite method.

I'm sorry man, but I think you blew a head gasket!
 How do your radiator hoses look when the motor is running? Black smoke and soot would be an overly rich condition. White smoke is burning oil or coolant This won't be cheap!

White smoke could be fuel if the fuel in one cylinder is not burning at all. If that were the case, you would be noticing a very rough idle. If the idle isn't rough, and the smoke is still there, then you likely have a blown head gasket. The 617's aren't known for cracking heads, so your head is most likely fine. Besides, the cracks the 603 motors get are not even close to large enough to allow large enough amounts of coolant into the cylinder to create enough steam to be visible.

Did somebody call me????
It is easy to tell steam from smoke, and I'm sure he would have notated steam if it were that. The only way I stopped the smoking on my 80 wagon was to sell it! I tried injectors (twice), valve adjustments (plural), IP timing, IP replacement, valve stem seals, thermostat (can't remember logic behind that one), made sure vac. pump wasn't compromised, same with sucking atf fluid back from tranny, my compression was 310, 330, 330, 330, 330. Didn't burn oil, blow by was darn near non-existent. Balls weren't missing in any prechambers. Chain was not elongated. Car missed horribly when first started. Had to work the pedal to keep it running. Would smoke like a train at idle and when coasting. Didn't smoke when accelerating or during high rpm's on the highway. Didn't smoke at all at idle when running diesel purge. Took about a minute to get to 60mph, and lastly, was getting about 17-19 mpg. Hope your luck goes better than mine did. Now back to your regularly scheduled programming........ Good luck!

Overreaction, maybe?
I think your problem is steam condensing on the exhaust and appearing as white smoke. Look around on the road, especially at cars just leaving their driveways or neighborhoods, and you will notice that white/gray smoke is normal in the cold, winter months. All three of mine do it (cold start, increase with acceleration). Just look up steam and exhaust and you will find a wealth of information. Further, search for head gasket failure to determine the more critical signs of this problem.
