Kudos for this video. There are a few other u-tube videos on this topic, so there are a heck of a lot of Toyota’s out there now that are having this problem, but this video doing the step-by-step process is spot on! And I do have the Haynes manual for all my cars, they are well worth the small price, it will payback several times over.
I had an 1999 Avalon and had the leaking and burning oil from the back valve cover and paid to get it fixed.
Now my 2001 Sienna Van with 264,565 miles (and going strong I might add) is having the same problem. I was leary to try to do this repair, but I will do a three for one fix; the valve cover gaskets, the plugs, and replace two of the coil-on-plugs as the eventually go, so I will do this once and be done.
Thanks again for the video lesson.

To fix the leaking rear valve cover gasket, first attempt to tighten all the bolts, they loosen up over time. You may need to move the brackets, take off the bolt and the bracket swings out of the way. And yes, gear wrenches 10mm and 12mm indispensable.

The hardest part for me was dealing with the wiring harness which skirts the rear valve cover gasket. I had to remove some connectors to get more play.. I’ve just removed everything, tomorrow i pick up some additional parts from toyota and start the assembly with the new gaskets , spark plugs , spark plug wires, half moons. I will probably be saving about $800 easy.

Thank you very much.

Bought Chilton. Bought the toyota repair manual. Your pics and explanation ended up helping more than both of them. Thanks a great deal.

Something’s holding it…. It has been years since I did this job but If I recall correctly there were more than 5 total, just have to feel around there until you find the one that’s not out yet. Could be a nut, bolt, plastic clip…. Sorry I don’t remember for sure.

I thought I poseted this earlier – so sorry if i did it twice…

anyway, the harness had a bolt that was hidden, 2 on the middle of the back valve cover, one at almost the end of the top of the valve cover on the drivers side, and then another that you pointed to on the drivers side. With those 5 out, the harness wont budge off of the drivers side, and I cannot see why.

Please, please help. I need to get this thing back on the road =(

thank you so much

First of thanks for such a great DIY.
I am stuck on removing the bolts near the firewall in the fifth photo of your second page.
There is a 14mm nut inside that metal bracket with only about an inch of room.
It is too small of space for me to get my socket set in there between the wrapped metal pipe and the formed bracket.
If you have any pointers on what I can do it would be great.
Again thanks!
