Hi All, I have burnt and unburnt oil coming out of the exhaust on cylinder 2. Compression and leak down tests were both good. Looking for suggestions on how oil could be getting in/exiting the exhaust? Some searching suggests a worn exhaust valve guide?
The car doesn't have an exhaust on it, so I am able to put eyes on the exhaust port. Thanks, |

Compression test - you’re clearly burning oil
That could either be coming past rings or pulled in through a valve guide. If compression is good then it’s all the more likely the oil is pulled past valve guides. |
