Question about 2004 Subaru Impreza
Engine shakes real bad it spit and sputters no horse power bogs down and now my spark plugs leak oil i changed the spark plugs clean the coil and spark plug wires
I just had this fixed on my suby today. The cause is that the spark plugs, go through the valve covers on the 2.5 l .When the o rings in the cover go, the result is oil in the spark plugs. The cost of the repair in Canada was about $500 including diagnostics as well as new plugs and wires About 1.5 hours labor and new seals and gaskets. It now runs like new. This is a common problem for this subaru engine as well as for the dodge neon.

Have you check to see if the piston rings still have a complete seal in the cylinder chamber?,
and is the oil leaking at all plug points?
oil leaking out of your plugs can only come through the piston chamber from my knowledge, and the only thing stopping that from happening is the piston rings, hope this info solves your problem for ya mate,
