I have recently acquired a 1995/6 3.0 Elite but it has a few issues I want to sort out.
I have read through the forum but can’t get a definite answer on this one.
The first issue is that there is "tappet noise" when the engine is cold or has been idling a while. After I take it on a fast run it becomes quiet, but if left idle for a while the "tappet noise" reoccurs.
I have added Wynns Hydraulic Valve Lifter additive for a couple of weeks, given an oil flush and replaced the oil and filter with Mobil 1 full synthetic, but it hasn’t made any difference.
I also read this noise can be caused by a manifold leak? or are the lifters or cams had it?
Second issue is burning oil smell? but I believe this is the cam covers? so I will clean out the breather system and replace the cam cover gaskets and do the cam belt kit /water pump at the same time.
Third issue there is some brown sludge at the bottom on the header tank? Is this to be concerned too much about? The oil cooler is on the way out?
I was thinking of just doing a flush and refill?
