Hey, what's leaking here? (Lower timing cover, valve cover)

    Oh, it is, but it's penetrated enough at this point that it'll be good for another 10k-20k miles

    I would say throw some ATP at205 in the oil after you clean it. Mine shows signs of VC leak way worse than yours, so that's what I did. Two tanks of gas and I already notice a difference. Waiting to torque the bolts down after another couple of tanks of gas. Mine were bad enough it sounded like an exhaust manifold leak, that's gone now.

    It's funny you mention AT-205. I had a mechanic friend toss this out over beers a couple hours ago. Swears by the stuff, "But only in the crankcase, don't bother using it for hydraulic or trans leaks".

    So I started to dig around to see if it's a gimmick, or what negative side effects I'd find for the engine. Instead, all I found is several glowing reviews, it's mentioned in a number of posts on Ih8mud, including this one from a Toyota guy which made me say, "aha!" ... the PCV valve on drivers side, and there's spontaneous leaking on driver side ... leaving me wondering if maybe I should toss on a new PCV valve, just in case this is pressure related. Not like it's that much $$ or hard to swap out.

    Oh, and I finally remembered the other thing I forgot earlier, never popped off the driver's side timing cover and take some pic. I swear, I've got the worst damn brain fog these last couple months. Really sucks.

    I should take a closer look at my VCs as I think at least my passenger side is leaking…too cold outside right now though

    I feel bad for all these low mile Tundras. They are going to die from lack of use.

    If you’re not going to drive it, let it go. Buy a Ford and get on with your low mile life.

    Sometimes the things you love you need to let go.

    Those NOK seals are begging for some love.

    Well, on the upside, I'm pretty sure it's only the VC leaking. I drove around quite a bit today, and when I popped the hood I'm only seeing fresh oil along the entire lower edge. I ordered a few bits from the dealership, including a new PCV valve. I'm ordering AT-205 this week, if swapping PCV does nothing, I'm giving AT-205 a shot, see if that works, and if not, I'll replace the VC gaskets when I do the plugs next go-round.
