OK I thought I'd change the oil, thinking this would be an easy job. Draining the oil was easy (2 drains). The manual says to remove the heat shield between the oil filter and the exhaust... I found this impossible, but could move it partially out of the way. I then couldn't remove the oil filter after it was unscrewed... to make matters worse, this was the smaller filter (289571 of the later cars) not the larger 188814 thats specified for my model... I don't see this mentioned as a problem on any DIY threads, am I missing something?
