Oil in EGR Passage

When the intake is in place on the engine, there is a hole that is located right under the intake EGR passage at the back of the engine. The hole is there from when the oil gallies were drilled into the block during the manufacturing process.

Check to make sure the freeze plug that was put into that hole is tight because if its not, then oil will go straight out of the block and up into the intake.

I had the same problem that you described (oil everywhere) and all it was was that freeze plug not being installed flush. I took it out, got a new plug, put it in correctly...end of problem.

Hope this helped.
