So like I stated in a separate thread, I had my last OC done at the dealer on my 2005 E46 and they put the incorrect oil (0w/30 FE) and I decided to change it myself. (I usually do OCs myself on this car but once in while I do take it to dealer when i have a coupon). This E46 has the oil filter housing on top of the engine. So I got my oil and the mityvac ready and used the usual oil filter cap tool with my 3/8 wrench and found that... I cannot loosen the oil filter housing cap AT ALL. I have always used the same tools and never had a problem with it. After some trying and no luck I was afraid I would damage the actual housing and/or the cap, I just gave up and changed the oil anyway, without changing the filter of course (the filter only has like 900 miles on it, so i am not worried about the filter really - just wanted to get the 0w/30 FE out and replace it with Castrol Edge 0w/40). No doubt the dealer service guy has overtightened the filter housing cap. (The housing cap has 25 Nm stamped on it) What shall I try next? should I just get another OC at the dealer and let them deal with it? I hate to waste the $ on another OC though. I don't want to ask them just to change the filter because I am afraid they would blame ME for it, if they break it while trying to open it. Is there anything I can try? (I did not try it with the engine warm, which i have seen suggested on forums - IDK if that plays a big role but it might?). Get a long 3/8 inch breaker bar and re-try? My 3/3 socket wrench is rather small. 8 inches max length probably. I don;t know how hard I should try though.... the cap of the filter housing is itself is not an expensive part, but I'd hate to break it. It is also not an ideal location to spray any type of penetrating oil/ WD 40/ PB blaster etc, and idk if it would even reach where the cap meets the housing...
