Oil leak under intake manifold?
Could anyone help identify what seems to be an oil leak under the intake manifold? This is an M52 engine with single intake vanos.
The pic is taken at eye level from oil filter housing gasket looking into the manifold where the CCV resides.
Marked with red is an unknown line going inside to a sensor that looks wet with oil.
For reference there's a big leak coming from the oil filter housing gasket to the bottom and side of the block. The main vanos oil line with banjo bolt also leaks. Could this be spraying oil to the intake manifold?
I'm currently doing an oil filter housing gasket replacement. I'm not sure whether I should take the whole intake off while doing this.
