Land Rover Discovery Upper Engine Knock?
I got a 98 Dicovery with the 4.0 V8----I am starting to develop a slight "Knock" from the upper end of the engine on the drivers side----oil changes have been done religiously at 3500 miles with castrol GTX oil----Has anybody come across this before??? Are the rocker arms/pushrods adjustable, as this could cause it, but I dunno
