2006 2.7 under valve cover pics

Odometer reads 165k miles. The first 120k miles were on conventional 5w30 at 5k intervals: Chevron Supreme, PYB, Castrol GTX. The next 45k were on synthetic 5w30 at 7-8k intervals, mostly M1 vanilla. Used standard oil filters such as WIX, Denso, Motorcraft, etc. Did this job because the valve cover gaskets were seeping oil onto the cylinder head and into the spark plug wells. It's been like that for about 6 months and the smell kept getting stronger, couldn't put it off any longer. Job took about 3 hours because I did some cleaning and other distractions but now I can do it in about 1 hour or less. Didn't get any pics of the cover itself but it's pretty clean and unremarkable. The perimeter gasket was stiff but not brittle, while the middle gasket (for the spark plug holes) nearly crumbled in my hands and was very difficult to remove from the cover. Replaced the factory PCV valve while the cover was off because it is a pain to access on the engine. Enjoy.

 

Nice work, looks great!

 

Mine looked similar at 230k. I have always done 5k mile oil change intervals and it looked surprisingly good when i pulled the valve cover off. Changing your oil goes a long way to keep things clean

 

My old 3rz looked like that at 200k miles. These trucks just need to be taken care of and they will last!

 

I did my valve cover gasket at 140k and it looked about as clean as @DGXR 's. I agree that sticking to the specified OCI is key to engine longevity, regardless of oil or filter type.

 

Looks great! Fortunately for us gear heads the shitty oils of the 90s are long gone and current spec oils do a phenomenal job lubricating and keeping things clean.

 

wish photos were closer

an i seeing chatter on the cam lobes.....................

 

I'm not sure what chatter looks like. If you mean the light and dark "spots" on the surface of the lobes, that's just a reflection on the shiny surfaces. They are perfectly smooth.
