Fluid leak. At a loss...
Hey folks,
My 400 decided she wanted to spring an oil leak last week. Brought her into the shop and crawled under the car and the entire underside of the car was covered in oil. I noticed the leak due to it burning off the exhaust at stop signs and red lights. She never really "leaves her mark" on the pavement when I park her.
Cleaned off what I could and noticed that the driver side valve cover gasket was leaking...check.
also there was an insane amount of oil on the one cross member in front of the trans and the oil pan was covered in oil and dirt ...check.
replaced both valve cover gaskets and pulled off the oil pan and put new RTV on it. The previous owner had that pan off at some point and seemed to have used wood glue to re-seal it!!
Either way, Took her for a drive yesterday morning after the RTV on the pan had adequate time to cure. First drive, no smoke....second drive no smoke....third drive....damn. Smoke billowing out from under the car again.
My question is, does the 1UZ have a cam cap/seal on the back of the head that you can't really see with the engine in the car? I've dealt with so many 1JZ/2JZGTE/2JZGEs, but this is my first rodeo with a 1UZ on a regular basis.
Inputs and suggestions are greatly appreciated. (today after work getting some UV dye and degreaser and I'm going to have an intimate session with her underside
)

I guess it doesn't matter that no one had anything to say. Found the issue. Cam cap on the back of the cylinder head was...well...GONE....new one arrives tomorrow.
