Still need to get at least a compression test done. If valve stem seals are bad, oil will run down around the seal into the cylinder. If the rings are bad, the oil will get pass the rings into the cylinder.

So I removed all the spark plugs and all of them were black. the driver side back had large amount of oil and the passenger side front also. But like i said all of them are black. Im thinking must be worn valve seals. i cant imagine every piston ring is bad and there is not any metal or enything in the oil pan.

Yup, definately sounds like valves. One of the reasons I'm rebuilding an engine over the winter. These engines don't seem to last too long from factory and wear out quickly.

Checked compression 120psi or close to it on all cylinders . Will probably go ahead with new valve seals this weekend. Haynes manual has step by step instructions .... Looks like a good weekend project for me lol

Thank you to everyone for helping me with your opinions

hey, nice results on the comp check, it does sound a lot like valve train with what your saying, one thing that caught my attention was the oil on your hand from the exhaust, is you get the engine problem fixed get that cat checked also, may be bad, my cat is toast after coolant when everywhere in the engine cuz of a lower intake manifold gasket blowing, it happened to go through the exhaust as well

Yah, the person that had it before me removed the cat. I would suppose they thought it was bad. Mayb they thought that was problem with car at one time
I ll probably put the cat back on after valve seals are fixed lol
