Hi,

My 04 has a similar noise .
I get no tap at first start, then a tap tap under load when cold.
Once its warms up the tap is gone under load but notice this noise when i idle long periods of time.
Its a faint noise like a diesel sounds.


I have searched and some seem to have similar noise.
I run 0-40 , m1.

I am almost sure my oil pump is going to be the problem.
Im going to get a oil pressure gauge and see how that works out.
I searched but wasnt able to find any data on oil pumps for our cf.
Im assuming nobody has had to change it?
