Well stock downpipe must have hole or something there's oil weeping out of it and burning is this sign of a blown carbon seal?

Yes. The exhaust side is an iron ring. It's not a positive sealSo it would dump oil into the intake then not the downpipe there's smoke coming off the downpipe smells like oil burning coming through the mesh on the downpipe
Not going to answer for Bison but I can speak from blown turbo seal experience.So it would dump oil into the intake then not the downpipe there's smoke coming off the downpipe smells like oil burning coming through the mesh on the downpipe
It's always something lolLol I just put the engine back in jeez.
Usually the thrust bearing is wasted and the groove on the shaft where the ring goes thrusts into the ring and it's down hill from there. This is assuming that an actual component of the cartridge has failed. There's an undercut on the turbine end that is tapered to a singer. That's what is supposed to keep oil away from the ring. Sometimes it gets carboned up and can't sling the oil as efficientlyIn your experience bison what is usually damaged when it leaks past the ring on the exhaust side?
