hahaha my bad.... some times stuff dont come out right at 3am... but ya i can get new plugs too, and see if it helps any. basiacally im trying to figure out why im burning oil and cooliant. and so far it only seems to do it from time to time. just at start up's when its " warm" outside but not always? it hardly ever does it when i got to work " 5am'' but it also smells like theres fuel in the oil too?

If its burning coolant there could be 2 problems,one being a blown head gasket or a cracked head..

I would do a pressure test on the cooling system first and check the cylinders for coolant.

As far as the oil issue goes if your smelling gas in the oil its ring time..

ya im thinking maybe when we were cleaning my heads during the cam swap that we could of cleaned alittle too much off and made the head un even? and as far as the gas? ill try and run a compression test and see what it says. whats weird is that it only started doing this after my cam swap. o and we already replaced the valve seals....?

white smoke is usually a good sign of a blown head gasket or coolant leak of some kind. Oil will be a blueish type of smoke. Try running a catch can. Keeps all that oil and crap out of your intake. Thats what i run. Keeps your motor clean.

Funny smell and white smoke? Coolant for sure. You wouldn't miss an oil burn.

Next time open your mouth and lightly inhale it, I bet it has a funny semi-sweet taste to it.
