Have a 95 ej22 . Been burning a lot of oil. Just replaced the spark plugs left side fine right side was in bad shape. Replaced pcv value old one had a little build up on it. There r no visible leaks coming from anywhere else. So it's burning up somewhere in the engine. There is smoke at first start up for the first mile them none, could it be the piston rings that r bad.
Also I replaced the guide value seals and still burning oil. About 2 1/2 quart per tank.
Any and all help would be great.
