So unfortunately for me I have a passenger side cam seal leak. I noticed a leak in that area almost two years ago. I had just performed a timing belt change and during that maintenance I saw no evidence of a leak. Anyway the leak is definitely coming from the front of the engine just under the VVTI cam assy. I had recently changed the valve cover gaskets thinking that somehow it could possibly be the issue. No luck. So I'm looking for a Toyota shop or dealership in the area that has done this work before. Because its a later VVTi motor my understanding is that the head needs to be removed etc.
