    Hi all,

    I picked up a used 4.7L 2UZfe engine from the wreckers with 150K. I noticed the driver's side valve cover bolts weren't torqued. After removing the valve covers for paint I see internally one really clean and shiny passenger side cylinder, and one dirty and dull driver's side cylinder (overall the colour is just darker and dull for all the components and looks similar to my old engine with 300k).

    The dirty driver's side does show signs of failed spark plug tube gaskets with some build up of oily dirt around and below where the gaskets sit (two rear tubes).

    Would the failed spark park tube gaskets cause the inside of the cylinder to look more aged as compared to the clean passenger side (where I don't see failed tube gaskets). Has anyone ever seen something similar before?

    Kinda worried I have an engine with one old head bolted on but it seems so unlikely that this would be the case.

    Appreciate it,
