When doing an oil and filter change on an SE5, note that the longer 6Mx35 Allen screws fit the smaller trans filter,and the shorter 6Mx30 screws fit on the larger engine oil filter. If you place all the oily pieces in a drain pan, you may get them mixed up (guess how I know). If you do so, the filters will appear to seal up, but the engine screws will bottom out just before a complete seal is achieved. The result is a slow oil drip from the engine oil filter, which may cause you to check and recheck the O ring for possible flaws. Just a word to the wise from someone who wasn't.
