Well, I started buring some serious oil. 90% of my driving is interstate so I got really concerned... Checked my spark plugs, perfectly clean. Checked and replaced my PVC valve, as it was free with a gift card. Gave up and just pulled my tubo... WOOOOOOOW... it definently blew a seal or had a bad one on it. Had a huge oil burn spot on the exhuast side and has a bunch of blue poweder smoke stuff on the inside. ( I call it powerder because I really don't know how to describe it). So I called the company that took care of my turbo rebuild. They are going to replace it for free... just have to wait till I get my new on then it will be time to re-install everything
