Aluminum Oil filter cap assy leaking
2018 4R SR5 at 30k miles.
Last oil change I replaced the original plastic oil filter cap with a TOYOTA aluminum oil filter cap bought from Amazon and advertised as Toyota genuine part 15620-31060.
Replaced the inner cylinder with the one from the original oil filter cap, bent the tabs back out, etc.
New gaskets, oiled before install, everything torqued to specs, I noticed the cap screwed in very easy all the way to the end. The plastic cap was getting really hard to screw in about half the way, and had to use the filter cap key to be able to screw it all the way in and torque it correctly. Didn’t think anything of it, torqued the aluminum cap to spec (even though it was kind of bottomed out), and away I go.
I kept on eye whether there is any oil leaks and after about 350 miles I noticed a light glinting below the oil cap. I dropped the engine skid plate and found that indeed this thing is seeping oil.
I ordered another identical part from Amazon to test, see if maybe I got a bad part …. Will get it tomorrow.
Anybody experienced this ?
