Smoke???

FIX THE PROBLEM FIRST OR YOU WILL DESTROY THE NEW CATS . THE RIGHT WAY TO FIX THE BAD VALVE/BAD SEAL/GUID/HEAD GASKET/CRACKED HEAD PROBLEM IS TO TAKE THE HEADS OFF AND SEND THEM TO A MACHINE SHOP TO BE REPAIRED ,OR GET A NEW SET OF HEADS ..

ok but who said it is

"BAD VALVE/BAD SEAL/GUID/HEAD GASKET/CRACKED HEAD"

I mean the truck runs fine except when I come off throttle and slow or stop after driving at 80 for 1.5 hours

To me everyone that has had a similar problem whether it be on the H2 or a different car claims bad seals and/or a issue with vacuum (involving the coolant).

I would like to try to fix this issue with the "snake oil" first since alot of others have stated success with it, but if not then sure lets fix it..... just cant see jumping into a HUGE repair bill if it can be fixed cheaper or if it isnt all that (even in my practice, I tend to diagnose my patients with the lesser "what ifs" before I start going after the bigger "what ifs". No need to diagnose for a brain tumor when it could just be a headache from blood pressure. HUGE difference in treatment (cancer - well you know all they go through, headache - oxygen and a pill).

But I appreciate the help and ideas.
I will keep all informed

ok heres the latest
the oil additive didnt work. i found out today that there is something drpping from my engine and that is cause the white smoke to appear from behind (because of the forward motion)
I cant tell what the culprit chemical is, but if sitting still and i rev the car for a while there is no smoke, but underneathe i witness something drip drip dripping from the engine area.
(this would explain how once or twice i saw the white smoke come from the front and once or twice i saw it come from the sides)

so i am guess i have an oil leak even though it doesnt have a real oily smell to it, but a chemical smell with a hint of oil. i will try to get under there tonight

So is the oil level low or the water level low ? If it is leaking it will make what ever is leaking low .
