I am in the process of changing the engine in my 2005 T-reg. I purchased a used engine that supposedly has 80k miles on it. Judging from the dirt and sludge in the intake manifold and in the valve train I am doubting the millage on the engine. Anyways my plan was to change the timing chains before I put the used engine back in but the chains are tight with no play and I cannot see any wear on the upper chain guide. There is also two red marks pained on the camshaft markings which leads me to believe the chains might have been recently replaced. Does anybody have any advice, what to look for or anyway of knowing if the Timing chains are original or if they have been changed?
