My first post is unfortunately a "what's this noise post" but I am wondering if anyone could give me an idea of what might be going on.
Sound is a tick keeping tempo with the engine, almost like a diesel. Sounds like it might be coming from the belt area in the front, but I'm not sure. I held the screwdriver near the front Driver side of the engine and around the spark plug area and you can def hear the ticking going on in there. No sound coming from the rear plug areas. Also, it seems pretty loud from underneath the engine. I'm not sure if its a lifter or something more serious like a rod or bearing.
As im trying to type this, all these symptoms are leading me to feel this could be more serious than I thought.
Any help is appreciated. Oh yeah its a 02 pathfinder at 130k, not sure if it shows up under my name. Thanks
