Replacing Spark Plug Tube Seals 1990 Legacy LS Sedan

Featured Replies

I have oil soaked spark plugs on the bottom side and I think my tube seals are bad but how do I get to them to replace them? I can take the valve cover off but the spark plug holes are above the plate.

There are no tube seals on the 2.2.

Oil leaking from the power steering pump or the pressure switch on top of the block.

Could also be filler tube gasket leaking.

90 doesn't have spark plugs running through the valve cover so there aren't any tube seals
