Im experiencing loud ratling noises from my car's engine(BMW 328i M52 Single Vanos)My suspicion is that my hydrolic valve lifters are finished or may they just be dirty. Should I replace all or can I replace just the ones that are finished or can I just clean them?

Re: Hydrolic Valve Lifters.(Vanos) Replacing
The lifters can be cleaned by getting the engine nice and hot and then adding an engine flush to the oil and leaving the engine running at a high tickover for about 15 to 20 minutes, and then giving the car an oil and filter change.
Are you sure its the tappets and not the timing chain?

Assuming you have a 1996 328i convertible based on your photo as there were no US 96 328is.
It is located at the left front end of the the engine cylinder head under the plastic cover behind the VANOS solenoid next to the top of the oil filter housing. In addition to the new sensor, you will need new metal o-rings for the VANOS line, a new rubber o-ring for the camshaft sensor and perhaps a new socket head cap screw if you round out the internal hex trying to loosen this Loctited screw.
See Figures 1 & 3 at the following Pelican Parts link.
Is it a high pitched noise you are asking about..?? Probably a fan belt slipping.. Or is it burning oil That concerns you?? Or is it fuel getting into the oil that concerns you ?? 328I.. does it have the 6 cyl engine? one of the most dependable and long lived engines ever made..
Hi, not sure from that end but how many km you have on that car, cose if it done 100,00.000-120,00.00 km You realy should pay attention or replace your timing belt, cos the noise you hearing could be from there not your valves, but if not changed in time the damage from that could escalate on that car to anywer $2-3 K, eazy. Anyway it just a thout 4 you. G/luck.
If there is a ticking noise on the engine it may be that your engines hydrolic valve lifter's may be failing. The reason why it may be a running problem is that the valve lifters are part the VANOS system witch is BMW's answer for variable valve timing. you have the M44B19 engine witch only has VANOS on the intake cam shaft. I cant be shure with the infomormation I have if this looks right and you require more assistance.
