Symptoms of head gasket failure include: white residue (tapioca) in the valve cover, under the oil filler cap, and in drained oil, low coolant (not caused by failure in cooling system), low oil, oil leak onto exhaust manifold, and loss of power from loss of compression. Cooling system trouble on the M52 must be addressed quickly as the aluminum head is easily damaged if overheating occurs.
This is an OEM E46/E39/Z3 head gasket set manufactured by Elring - one of the original suppliers to BMW for these gaskets, as well as many other gaskets and seals. As the OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. These parts have a two year warranty.
