    2018 with 25k miles. I do have passenger side cam tower leak but while inspecting the other day after dealer verified cam tower i noticed a different leak towards front of the engine passenger side. The pics below are through the wheel well and the exhaust header is to the left and back of alternator to the right. My first thought is timing cover but also looks wet where head meets block, maybe just oil migration???

    It could be what you think and it’s Probably not the case, but... have other people checked your oil level? It could be drips from dipstick spatter when checking the oil (without a rag at the ready.) If so, there would likely be other random spots in the engine bay?

    I am going to get a better look from underneath with a mirror in the sunlight and see if I can trace it a little better.

    IIRC, the valve cover extends out over the front timing cover. It may be leaking at the valve cover/timing cover joint as you said, and then migrating down and then back along the head/block joint. If you're having the cam tower leak repaired, all that should be removed in the process and resealed anyway. I doubt that it's leaking oil at the head/block joint; if it is, you've got bigger problems than you think.

    Toyota has known about the cam tower leak issue for years yet it's still happening. WTF!!! I'm afraid to look at mine...
