p0306 oil in cylinder
The other day out of nowhere my van started acting up under load and the cel illuminated. I found p0306 Got home and checked for spark and it was good. Pulled the cylinder 6 plug out and found the plug to be damaged and has oil covering plug. I looked down into the plug hole and can see cylinder has oil in it. I dont have a compression tester but to me it seems that may be the case here. Is there a way to check it out without tearing the engine down? Im thinking its going to end up being rings...

With only one cylinder having oil, IMO a leak down test would be much better than a compression test. The compression test will tell you what you already know, but the leak down should be able to pinpoint the specific problem. And that will give you a much better handle on the cost of the repair. If you can't borrow or rent a leak down tester, a shop might charge a reasonable amount of $ to test only #6. With one of the front cylinders, it shouldn't take more than 15 minutes, in and out.
