Hello again Folks. I've held off for a while asking this question fearing embarrassment, but I can't figure the darn thing out. I am trying to remove the engine cover on this car in search for the oil filter. I tried pulling up on it, but it doesn't want to come off with moderate effort. The cover on my ML430 pops right off. This one, is hanging on with dear life. Are there unfastenable clamps or screws holding this sucker on? Thanks. -Norm
