I have a 92 525i sport with 350,000 kms on the clock , my engine has rattled from cold since 150,000 , its your lifters draining down over night , it`s a milage thing , just keep your oil clean..no more than 6,000 intervals and forget it..

My 1988 530i takes 10 seconds from start up for the oil
pressure light to go out, if the car has been left switched off overnight.
A pressure gauge has been used to confirm the pressure switch function is correct. A new oil filter and oil have been installed. Cold oil pressure is
4.5bar and hot is 1.5bar, both at idle. 2000rpm sees 5 bar.
I am at my wits end. Can anybody confirm if this engine has a non return valve in the oil system.
Could the pressure relief valve be jammed open letting oil drain back.
Or is this normal for this engine.
Help
