After I turned my '96 up I noticed a little more blowby than before. Is that a normal thing or should I be worried?

Could it be it's getting colder and it's steam you're seeing?

More oil around the tube. I have'nt paid attn. too it while running. It has never blown out enough to make a drip, but it seems a little more oily. Maby it's just my imagination. Should'nt there be a little oil blown out?

The more fuel you add the higher the exhaust temperature as well as the firing pressure it's a balancing act. More blow by could be from higher firing pressure in the cylinders which could force more of the combustion gasses passed the rings to the crankcase and then out from there (vent tube or oil fill). The timing of the engine will also play into this.

When I tore my motor down last month the blow by on it was pretty bad considering it was lifting the oil dipstick off the tube. I had smoke coming out of the vent tube on the side of the block like it was smoking a cigar.

exactly what mine looks like and if you let it idle for prolly 15 mins or so it will leave a half dollar sized puddle of oil.

Mine is doing this too. The pressure is pushing the dipstick tube up and the vent tube down below is really blowing. Its right above the u joint on the front drive shaft, its covered with oil and I thought the seal was leaking until I looked up and realized it was coming out of the breather tube. What causes this blowby? Is there a vent somewhere that can plug up? The valve cover gaskets are seeping some oil too.
