My recently acquired E30 M42 has 196K and I am getting an occasional but definite chain rattle/slap @ around 3000rpm. (Don't know how I missed that on the test ride. )
My Sprockets [Photo Link] certainly look worn, but are they TOO Worn? The intake cam sprocket looks more worn to my eye. In addition she appears to be leaking a fair amount of oil out the front crank seal.
I've have a new tensioner in hand but I'm hesitant to pop a new tensioner into a worn system especially with the "Rev to Pop Tensioner" procedure.
Any Comments on the relative wisdom of the following plans?
A) Replace Everything - Sprockets(3) chain and guides, seal, gaskets water pump. (~$550.00 parts)
B) Replace Everything except for Sprockets. (~$430 parts)
C) Replace Rails, seal and water-pump, gaskets but leave chain and sprocket as is. (simpler procedure? )
D) Pop a new tensioner in, hold my breath and see what happens.
Any knowledgeable advice on this would be appreciated. [LowerPan comes off for UpperPan bolt check tonight...]
Thanks!
