As long as you are continuing with regular OCI, and your oil and filter are clean (no water, metal, sludge) You can leave it in there. As someone suggested, oil will circulate through there.

My recommendation, is pull it out at 5th oil change (25,000km) and properly flush and leak test. You have good OCI and good oil, you can increase that interval accordingly.
