    you are burning coolant.. check your oil dip stick for a milky color . If its milky head gasket is blown.

        Nothing he said confirms that.


        White smoke is coolant. It has a sweet smell.
        Blue smoke is oil. It has a "thick" smell. Very obvious.
        "Whitish blue" means nothing, unless you happen to be burning both oil AND coolant (possible with a bad head gasket.)

        It could very well just be condensation burning off, which has no smell whatsoever. That is actually more likely than anything else, since it only happens when the car is first started after being allowed to cool for a while.

        However, don't EVER assume that just because something has been replaced that it can't be bad. Any of the new parts could be bad, as could the installation. I've seen far too many people on this site over the years that refused to believe their new part was faulty, and threw an unnecessarily large amount of money at the car replacing everything else.

        There is no such thing as a "steam valve". If your buddy said that, he knows no more about cars than you do.
        If the head is new, no valve seals should be bad. If they are, then whoever sold you the new head either sold you crap, assembled it poorly, or lied. In fact, everything in the head should be new before installing it... so your issue, if it's not due to a faulty head or installation, is in the bottom end. If you're burning oil, it's more likely to be the piston rings (if there's nothing wrong with the head, of course.)

        Do as Ely585 said, and check the condition of your oil and coolant. If there is any evidence that they are mixing (a milky appearance), then it's the head gasket. Take it back to whoever installed it and demand they redo it properly.

        Otherwise, make a better effort to identify exactly WHAT is burning, and we can help better from there.

          I had the same problem with my buddies H22 head, and he had the machine shop replace the valve seals and 6 bent valves. What ended up happening was the valve seals where not installed correctly. So there for anytime the car sat for a while, oil would slip by the seals and puddle up on top of the piston. Then when he went to start it up, it would smoke at first because of the oil. He took it back to the machine shop and had them fix the seals, now the problem is fixed. Hope this help's.

            yeah that was the same problem, i had a mechanic look at it, and the valve seal was completely destroyed even though my other mechanic said he changed them and put new ones, but meh my baby should be up and running tomorrow after the seal gets replaced
