What the heck is going on?!

[Polyal]

Ok, well for a while I was having issue with my car blowing smoke on start up for a good 30 seconds. Now that the warmer weather has come it has seemed not do it as often or so much. Which would explain why it didn't do it when I brought it this time 12 months ago.

Anyway, everyone said replace the valve stem seals, which I did, but it still did it. And when I took the old ones out they really didn't seem that bad at all. It seems once the car sits for atleast 5 hours that oil builds up somewhere and then gets burnt out. Meh.... :

So what do you think it could be? A sensor issue? I am a little over it but would like it fixed.

My other problem now is that it has been running rich basically since Ive had it, but on highways I will easily getting 600-650k's per tank, and around town when I take it easy I get around 450 which to me is acceptable.

But...there is a really strong fuel smell, sometimes i notice it but i think Im used to it, the GF complains about it all the time. She was driving her car behind me yesterday and said she can even smell it then.

I just cleaned the boot and its very very strong in there, so it must seep into the cabin.

Dont get me wrong, it still goes pretty hard, actually I showed up some done up HG? V8 ute last night, the outside looked like he had done some work anyway. :

My exhaust tip is very black, as you can see from these pics. Any idea whats going on?

Here are the pics (sorry photobucket seems to be down)
