All,

I am getting a small but messy amount of oil from around the connector between the turbo and the intake manifold.

Of course, there are at least 2 issues here:

1. I have noticed that I can get new rubber O-rings for the connector. Since I have leakage there I guess I should do that.
2. But the bigger question is should I have this much oil at this point in the intake? I have removed/blocked-off the EGR and replaced the trap-ox with a bypass test pipe.

Note that I have a '85 KaliKar 300D, so my valve cover breather connections are different than most. I have tested with the oil breather line disconnected from the turbo inlet (plugged both the oil breather connection to the turbo inlet and the turbo inlet) and had the same results.

Does this indicate oil blow-by at the turbo seal?
