northwestguy1 Posted February 17, 2016 Share Posted February 17, 2016 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. 1 Link to comment Share on other sites More sharing options...
Fairtax4me Posted February 17, 2016 Share Posted February 17, 2016 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. 1 Link to comment Share on other sites More sharing options...
mikaleda Posted February 17, 2016 Share Posted February 17, 2016 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 Link to comment Share on other sites More sharing options...
johnceggleston Posted February 18, 2016 Share Posted February 18, 2016 or if the oil is on the lower side of the plug boots, it could be the valve cover gaskets.?.?.?.? Link to comment Share on other sites More sharing options...
