First oil change on G5 last night. It took a while to get O-ring, Filter, O-ring, plate, O-ring, Washer, Spring, gasket, and cover with O-ring all in order and aligned with spring compressed to get bolts started. Had a thought: What if I made two studs with knurled nuts. Put studs in engine. insert filter, etc and start cover. retain cover with one nut on one stud. Remove other stud and insert bolt. with cover retained by bolt, remove second stud and insert other bolt. Studs should be short enough to allow cover to be moved side-to-side to align as necessary.
Would this make the process easier? The other alternative would be a thin tool to hold the spring compressed until the cover can be aligned and screws started. There may not be enough room for that. Next time I will make some measurements to check. What are your thoughts? GA-DK
