Recently my 1uz developed noticeable coolant leak down there (plug p/n 11492-50010, replacement p/n 11492-20010)
Removed the plug, it had signs of black sealant
Grinded the remains of the sealant off with sandpaper, applied new sealant, reassembled
After a while I noticed the bloody leak again. I can't spot the exact leaky point but it's definitely somewhere near the bottom stud
Opinions, anyone?

I suppose it may even leak from the stud, not the hole that's blocked by the plug
