    All modern engines seem to be more prone the leaking (partly because of water for oil, 0W-20), hell some new chevies don’t roll off the showroom floor without leaking rear mains.

    So my ‘11 has had a slight weep for a while but never bad enough to be concerned about. Recently I started leaking and leaving stains in the driveway and would swear it was the rear main untilI noticed an oil drop forming above my header today. I can’t see it running down the motor anywhere but that doesn’t mean it’s not happening. Have you guys ever noticed the oil from the cam tower leak collecting on the bellhousing and dripping onto the crossmember?
    Thanks

    Usually not. I’ve seen the valve covers do this though. Best thing to do is buy some good degreaser, clean the engine off REALLY WELL and let it run while watching if it’s leaking that bad. If not monitor it once a day or week to see where it originates from.

    Thanks. I’ve been degreasing it for a week and still don’t see it draining. I’m assuming they’re both leaking at this point but I’ll have to tear it apart this weekend to know for sure. But on a positive note besides the sun beating up the paint I haven’t had a single issue with it until now at 152k miles so I can’t complain much.

    Why TF isn’t Toyota using the black sealant to assemble these?

    toyota always has used the grey stuff from the factory. black is what we get at the dealer. its identical other than the color. difference is dealer we probably put it on a bit thicker than a robot does

    Alright. Well, maybe the leaking is just inherent to the design and doesn’t matter what sealant?

    Otherwise I would assume the robot using more sealant would surely be less expensive than warranty repairs.

    Maybe leaks aren’t all that common even if it seems that way on a forum.

    I'm sure this is a first....

    In July, I took my 2018 Tundra which I noticed was leaking at 6000 miles (now 15k) to Toyota. They confirmed it was leaking, didn't do the 10k oil change because they would be doing it when the leak is fixed. They ordered the parts and about 2 months later I finally took it in for repair. I dropped it off 4 days before appointment because I was out of town for a week. On the first day of repair, I receive a call from the service dept., stating the truck was ready.
    Here's a bit of our conversation....

    Me: WHAT?? What about the leaky cam tower??
    Toyota: "Our mechanic says there is no leak! The oil on the cam tower is from the rust protection overspray."
    Me: "I called 4 weeks before my appt and asked if it was a bad idea to have it sprayed 3 weeks before my appt, and you said it was fine?"
    Toyota: "That's enough time for it to stop dripping, again, the oil on the cam tower was from the overspray, not a leak"
    Me: "Can you ask the last mechanic who said it was leaking why he he said it was leaking?"
    Toyota: "That mechanic is on sick leave"
    Me: "Can I speak to the CSR who helped me and stated the truck will need the repair and parts will be ordered"
    Toyota: "She's on sick leave as well"

    So, the mechanic and the CSR who initially helped me are on sick leave and now my truck no longer has a leak? I also received a phone call from the original CSR telling me to make my appt because the parts were in. Of course I showed the new CSR my posts from this site/thread with a picture showing a leak at 6k miles. I also showed him a picture of the leak around 10k miles. Not good enough though, he wasn't buying it. I told him I will be back in 6 months with a leaky cam tower:mad:

    Ridiculous!!

    sounds to me you have a tech that doesnt want to deal with the job (it is terrible paying under warranty) I would look into a different dealer personally.

    On my 2021 the sealant around the valve covers is black. Is cam shaft tower the same as valve covers?

    No, they're not. I took a couple pics for a friend of mine when he was shopping a used 2010. Try to find on your truck the points (lower eyelets) where I have the stick pointing. These seem to be the locations where they most often (but not exclusively) show the beginnings of a leak.

    The first one kinda sucks to see, but the later two show the black sealant from when mine was resealed. There isn't any sealant on the valve covers.

    Thanks I watched a video on you tube. So on my 2021 the sealant for the cam towers is black. Almost looks like Permatex ultra black but its anybodies guess. that's a pretty involved job, if it wasn't causing issues I would let it leak if out of warranty.

    The Cam Tower fix calls for P/N 00295-00103, I have/had a tube of it around here someplace. It's about $20.
