03 350z ingested water and locked engine. Removed plugs and cleared cylinders, changed oil and filter. Now runs but has clatter. Sounds like coming from upper area near cyl.#2. On a pushrod engine would suspect bent push rod, damaged rocker arm or lifter. Removed valve cover and timing cover. No obvious damage.
Any ideas as to what is causing the noise? Don't want to pull the head and find nothing.
