Customer Question

Hi Mike
I have a Range Rover Vogue with a 4.4 M62 engine, upon start up from cold there is what sounds like a rumble for 2 seconds then drowns out under normal engine noise(this doesn't always happen), when engine temperature is at normal, from the o/s bank a tapping noise can be heard. I've replaced the vanos solenoid and have also tried thicker engine oils, the engine has covered 95k miles and has full service history, also when the engine revs are increased the tapping noise goes.

I'd 1st suggest measuring the actual oil pressure with seperate mechanical gauge - this can be plumbed into the engine via the current pressure switch port -

If you do have a low pressure reading then replace the oil pump and ensure that the pump pickup in the sump hasn't come loose or is blocked

my thoughts are that the rumble is a worn main bearing and the tapping noise is a valve / cam follower

both of these need a full level of oil pressure to function
