I'm guess that you are talking about smoke out the exhaust here, if I'm wrong... oh well. It could be fuel as well.
Firstly do some really basic checks... and answer these questions
Is there water in the oil?
Are you burning alot of oil?
Do you have much blow by?
Do you have air being pushed out the radiator with the cap off?
What is the compression like?
Have you done any mods to make the car run rich?
Then get back on here and ask the question again, because you are way to broad at the moment.

ok sorry about that.... 1st yes it's out of the tail pipe.
It doesn't appear to be water in the oil...but i'm not 100% sure how to do this. But in my last oil change (a week ago) i didn't see any appearance of water.
I have synthitic in, i wanted to try it...but it seems to be about a 1q or 1q 1/2 per oil change....normal oil, i don't know about the synthtic.
I don't know about the blow by help?
I haven't checked i'll do that now, so if i take the main cap off the radiator (the one dead center up front) i am listening for it sucking air?? won't that depressurize the system? or cook me with fluid??
I have to check the compression
I have not done any mods that should make it rich

To replace the valve seals read this thread about rebuilding your head:
http://www.mx6.com/forums/showthread.php?s=&threadid=39955
Removing the head isn't that difficult just a bunch of things to remove; intake manifold, exhaust manifold, egr pipe, distributor, timing belt, valve cover, drain oil and coolant, release fuel system pressure, and I am sure there are some other minor things. Get a hayes manual on the probe, it will explain what needs to be done in what order, plus give the torque sequences for the head bolts.

I didn't mean to suck air in the radiator.... me is silly, I meant push air out... I never read over my post. DUH!
If you have a blown head gasket you can experience different things going wrong with the car, and depending on where the actual break in the gasket and how big. Different things are required to check for depending on where the break is (and you don't know this yet).
IE - Water in the oil etc.
Sometimes you will find that the engine instead of pushing air out the exhaust the air will go into the water in the engine and hence come out the radiator.
To test for blow by, just start your car (in neutral or course
) Then take off the oil filler cap.... blow by is when you have loose seals on the pistons rings or the valves aren't closing properly... or both. This way the compressed air in the cylinders is slipping past the piston rings and out the top rather than out the exhaust. Now, being 13years old, your car probably will have some blow by. There is no real amount where you say... I need to fix this now. But in my opinion, if it is starting to smoke, and you can't find any other reason, and you have oil being thrown out the tappet cover... then you may know why
Hope this helps.
