Leaking oil on cat. converter

[herblatham]

I switched over to full synthetic 10w30 castrol a little over a month ago, and started leaking oil on the cat. converter right side of the disco, causing it to smoke a lot. It started out not doing it but every once in a while, when i was at a stop light or gas station. It now has been doing it every time the car comes to a stop. I've searched to find where the leak is coming from, with no luck. any ideas on where to look for the leak, and how to fix it? or does this sound like something i need to take to the shop?

Sounds like a valve cover leak, this is normal with or without synthetic oils. You can change the valve cover gaskets or you can go off roading a few times and build the mud up around the engine to prevent leaks...

Just remember if it stops leaking it is out of oil.

changing the valve cover gaskets....what kind of skill does that take to change em out?and how much time?

where on the RAVE CD could i find this?
