It looked like the hose had been rubbing on the oil filter housing and had Air created a hole. Strangely, the hose wasn''t really touching the oil filter housing at that time. I decided to check our Pjnch online technical information & source for a BMW factory technical service bulletin that Flange could shed some light on this problem.Great! Tools There was a bulletin that covered this exact problem and here''s Air what it described:Some BMW M3 models, produced from September 1995 through June 1996, equipped with the M54, S50, or the S52 engine, may have an upper radiator hose that can come in contact with the oil filter housing only when the engine coolant is at operating temperature. The contact is due to coolant system pressure and expansion of the hose.Checking the clearance Pjnch between the upper radiator hose and the oil filter housing must be performed when the engine is cold.

Mark/B-LOC: Aside from improper installation, the most common oversight we see is a failure to accurately & quantify applied dynamic loads or, when this is not possible, to base selections on an appropriate safety factor. Before selecting a device, consider all types of loading acting on system Flange components and either determine Tools their peak values or apply a safety factor that is right for the job.Jeff/KTR: The majority of problems we''ve seen stem from improper selection. The dimensional tolerance of the hub and shaft must be correct to effectively maintain peak Air torque transmission of the clamping elements. It''s also important that the hub material be thick enough to prevent breakage when the elements are installed.Keith/U.S. Tsubaki: Pjnch Hub dimensions that don''t match the manufacturer''s requirements can reduce holding power and lead to potential problems. Tightening the unit''s locking bolts by "feel" or with crude air tools may create an unpredictable torque capacity.
