Yes you can drive the car after the burp. I experience the burp every cold morning when I start the car. Just after you drive it for 30 minutes or so look under the hood and make sure that nothing has popped out of place or is leaking like the valve cover gasket. But I'm actually getting the oil seperator replaced today! Its at the shop, Already had my valve cover gasket replaced, it blew...That was a direct result of a severe burp one morning..

As far as the DIY. I know one member here has done it...I believe his name is lojack...GL.
