If you want to replace the pan gasket, it depends on the vehicle. You may have to lift the engine to access the bolts ,lower the pan enough and remove the old gasket. For the year Rav you have , patch it with silicone is what I would do ,if you can.
The type of leak you describe does sound like a cam or crank seal. They tend to seal better once everything warms up. You say you replaced the cam seal already??? It might not be seated right??
These newer front wheel drive engines are still unknown to me , haven't had to do much maintenance on them.......yet!
i'm still not convinced it's the cam seal a friend of mine and i replaced, and i hope it's not after all the time i put in replacing the cam seal. I struggled to remove the engine mount, and again when re-installing it. there must be an easier way. somebody who works at my local parts store said there was a dedicated tool for this pesky engine mount ( he said he also worked at a toyota dealership), and that only the toyota dealers had the engine mount tool.
Besides, the leak is at the back of the engine, not coming from the side of the timing belt cover, thus in my opinion ( i hope so!), disputing the suggestion that it was a cam or a crank seal leak.
there is wetness near the seam if the oil pan in the back. i only see oil stain on the ground during warmups.
how about using a dye in the oil to detect the leak. i never used it before. there is a special light that's used to see the bleeding. i wonder if it's affordable or for rent. have you used the dye before?
