So when we machined these oil caps we did use a valve cover to index the cap the correct facing position but finding out later that valve covers are not all made the same . You can see where we did machine a pin hole for indication .  Also the seal under is rubber so depending on you muscle arms out there it could be over tightened also. Go to Ace hardware or where ever you can to get a small oring to go under the factory seal I sent with cap. FUNNY THIS WAS BROUGHT UP . When I install the oil filter on my builds it does drive me crazy if I don’t see TOYOTA writing after installing .
