The entire left rear of the block is wet with oil - not fuel. It starts just under the intake/exhaust manifolds and runs down the block.
My first thought was to change the head gasket, but I'd like to see if anyone had any ideas or had seen this before. Compression is even across all cylinders and I'm not burning an excessive amount of oil.
Anyone seen this before or have any ideas or guidance? Thanks! | | |

The leak seems to be coming from in between the bottom of the head and the block - where the gasket is. This seems strange to me, as I didn't think there was any oil circulating near there.
Maybe it's just a bad head gasket, but it just seems strange to have a leak in that area... | | |

Thanks for the reply. | | |
