1988 mustang gt smoking
I have a 1988 mustang gt. I just bought it and the guy that had it before me had said it was overheating and as soon as i got it i have it a tune up and put a new radiator in it and i have it running and i had my friend fallowing me driving it and when i get on it i have blue smoke comming out of the drivers side exhaust and the other side is just white but when its at a idle there is no blue smoke. And when i changed the plugs on it they were all ddry besides piston #8 the plug was covered with oil. Any ideas what this could be?

The white smoke on the passenger side is probably coolant seeping into a combustion chamber from a leaking head gasket.
The blue smoke is coming from the #8 cylinder, probably from bad rings, or an out-of-round or tapered cylinder wall.
Unfortunately, you will be needing some work done to it pretty soon. Keep your oil and coolant filled up until you get it to the mechanic, and while you are at it, check the coolant for signs of oil, and vice versa.

im thinking the valves are bad on the head so i went and bought some gt40p heads for it. so im going to put new gaskets and new heads on and see if thats the problem. but do you think the valve seals could be leaking?
#8
Cylinder could have an irregular wear pattern. When I rebuilt my engine, I had to get it bored because there was no way I could have honed out the groove and ridge at the top of my #8 cylinder. One or two of the others had a couple grooves, and some were perfectly smooth, but #8 was pretty bad. In general, the ones to the outside had the most irregular wear, the inside ones were mostly decent.
Piston rings will sometimes slop around a little at the top of the stroke as they get some wear, so there is usually some taper or grooving in a circular pattern near the top of the cylinder and a ridge at the very end of the piston's travel. This can let oil pass into the combustion chamber.
