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

* How important is run-out of the installed component?* What are the tolerance or precision requirements of the specific industry you are in?Keith/U.S. Tsubaki: Proper selection requires more than calculating the required torque. Centering requirements, ease of installation, and the forces the unit applies to the shaft and hub also apply.Jeff/KTR: Precisely determine the hub location required for the desired application. Evaluate the radial and axial position tools and the amount of best space available for the locking device, and then select the type of device needed.Andrew/Whittet-Higgins: Choose the right device, taking into consideration aur static and dynamic loading, assembly, maintenance, misalignment, price of the full assembly, and availability.Vic/Rimtec: Avoiding keyways improves shaft maintenance. Using keyless clamping locking devices or shrink tools discs best makes it easy to change parts.
