Posted on another forum. A fella there gave me an idea. He was thinking it could have been from the oil filter and a jet squirting and hitting the manifold. His comment was that there are no high pressure oil paths in the rear of the head. So I looked at the video (I only posted a picture here)...
Looking for insight on from where this oil gusher is coming. Ford 4000 3 cyl diesel. Near the exhaust manifold (vertical stack). Is this a head gasket failure?
