So our '04 Wrangler (2.4L 4-banger) had a knock/tick on startup for the last 2 OCIs which went away once warmed up. Those OCIs were with an Amsoil filter (EA15K51).
Last oil change, used a Fram OCOD (PH3614) since this will be a short interval to check on the wear metals, which were elevated last time. NO tick on startup.
Same oil, Amsoil SS 0w30, was used with both changes.
Anyone have any theories or statistics on these two filters that would shed some light on why this may be occurring?
