about 3 to 5 mins and then stomp on it and there will be a bunch of bluish
white smoke come out the tail pipe and also i can keep it at 3000 rpm and a
steady smoke will come out but a small amount comes out and it kinda looks
white but the oil leave keeps rising lol have no clue there lol cause i took
some out to make it right then it went back up i dont under stand its not
milky so i dont know whats going in to the oil lol and it misses a little
but i think its cause of the oil in combustion chamber

Answer
Hi again, Holly,

Are you a dealership mechanic yet?

Well, the steady stream of smoke, blueish and white, even in a small amount, is happening for a reason.  The level is coming up, even when you leveled it off in the past.  That is coming from somewhere.  How much did it rise?

I don't know what your oil looks like, but if coolant was getting in it , it would look sludgy, light colored chocolate milk (or melted chocolate milkshake).  It would have that color, and thickness.  If it is a little bit, it may not be so severe in it's appearance.  

The blue smoke is oil.  Consistant blue smoke, like you describe, is rings.  The white, if not coolant, could be the result of a bad, or missing, CAT.  If that is plugged up, the exhaust that would be burned off, will get past it, and out the tailpipe.  Your O2 is probably shot too.  Oil kills all these components in the exhaust.  

200,000 miles, blue smoke constantly, white smoke, increasing level in the oil pan...it is time for some major work.  The compression was great.  However, the heads could be bad.  Is it worth fixing the head and not the lower end?  That is only half the work.  If you don't intend to use this for more than a few years, then go the cheapest way.  If you are going to keep this, and possibly restore it, then do the right thing.  You could save $$$ on the labor, doing it yourself.  Find a good used, or a new long-block.  Probably about $800 new, and $300 used.  Have you ever checked the value of this truck?  You can decide what it is worth.  Then decide what it is worth putting in it.  

You could possibly just do the head, and be fine.  This is based on the compression test results.  Doing the head will fix the worn valve stems, and seals, and the head gasket.  Remember though, I am not there to see in person, the condition and symptoms.  Being so, I would hate to see you spend the money on this repair and it doesn't fix the problem.  

Here is another option.  Since you don't claim any performance issues.  You could just drive this until it gets worse.  Then, do something then.  Meanwhile, save your money for the upcoming repair.  Or get another vehicle at that time.  Just watch the coolant and oil levels.
