It looked like the hose had been rubbing on the oil filter housing and had created a hole. Strangely, the hose wasn''t really touching the oil filter housing at that time. I decided to check our online technical information source for a BMW factory technical service bulletin airtoolsforwoodwofkers 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 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 between the upper radiator hose and the oil filter housing must be performed when the engine is cold.

Warren/Fenner: Failure to take into consideration the compression forces and outward forces airtoolsforwoodwofkers generated when using locking devices. The mounted component must have sufficient wall thickness to withstand the outward forces airtoolsforwoodwofkers or it will burst. Likewise when mounting on hollow-shaft or tubular applications. Inadequate wall thickness results in the hollow shaft or tube being compressed and distorted. Many manufacturers publish a formula or table that lets designers calculate airtoolsforwoodwofkers the required wall thickness.Vic/Rimtec: Having too much clearance between the shaft and hub is often a problem; you can''t clamp enough to transmit rated torque. Overtightening the screws is also common, causing tapers to lock when they''re supposed to disassemble. This is where locking devices with push-off screws come in handy.
