oil/fuel comming out the blowby tube.
fortunately this isn't happening to my truck, however, it is to a friends...
I friend of mine has a '92 with 177k on it. His truck recenty started getting oil comming out the blow-by tube, it also seems that there is some fuel mixed in with it. The truck isn't really bombed, with the exception of some screws on the pump turned. Any ideas as to what could be causing this?
My guess is there is a bad injector that is allowing fuel to seap out and making its way into the crank case, causing too much fluid in the crankcase, therefore causing excess pressure and pushing it out the blow-by.

thats a good guess .I would see if the oil level is High and by how much
the other thing could be exesive blow by from maybe a washed out cylinder.
Is it running good?

How about a bad lift pump or injection pump seal leaking fuel into the crankcase? The injector scenario would more than likely cause a single cylinder hydrualic problem if it were that bad.

I haven't looked at the truck yet, just relaying information. He said he was going to change the oil tommorow.
