22nd Sept, took car for a good blast yesterday, didn't rev to limiter only 6000rpm max, got home after work
and noticed the faint tapping is back, very disappointing., mechanics say they can't hear anything.
Does not affect performance or oil consumption, does not use any oil between services (6 month oil services).
Still the 5w/40 synthetic oil has made the engine slightly smoother and quieter than before..
23rd sept.. Tapping noise gone again, the only pulley unchanged on car is aux belt idler, so that will be changed next week, engine much
quieter on new oil so will stick with 5w/ 40 from now on....
Edit;July 2011; Obsession with tapping noise over, last year changed manifold gaskets and bolts and noise gone and still 6 months on quiet as a mouse.
Conclusion, nothing at all wrong with a fram filter, and 5w/40 FS oil definately makes my engine smoother.
