The EGR System is pretty aggressive on the MDX there was a thin coat of Carbon Build up in the entire Intake Manifold nothing was spared.. The EGR passages were un-obstructed either but considering how I take care of my MDX and only use Premium on it? It seems the EGR was tuned for complete overkill, My PCV valve was also healthy.
The valve covers and valve train itself is very stained on the front one.. The front valve train is heat stained to hell but the rear is pristine.. My TL-S had the heat stain on the rear and the front one was very clean but the TL-S was bought brand new so we had the maintenance done right.
The joys and glory of buying a used vehicle I guess? These are the kind of things you cant spot when looking at the vehicle before buying.
So your front valve train is with heavy heat stain just like mine and the rear valve train is cleaned as mine as well. I bet all MDX are like this because the PCV valve is connected to the front cylinder head. Make sure to check for worn lobes on the front camshaft!! I can't wait to find out!

I do off road with my MDX and México streets are all time covered in loose dirt.Dude, what's that dust all over everything? If my dog were half that dirty, I'd give him a bath ASAP. :grin:
I lived off a gravel road years ago, so I know all about dust shaming.I do off road with my MDX and México streets are all time covered in loose dirt.
Those areas are beneath the intake manifold as well so I cant clean it with a rag easily, They will get cleaned for sure because of this but at the first off road trip they will get all dirty again anyway.
