I decided to change the oil on my 2007 4.7 L but when I went to remove the filter I found that it did not turn. I tried the trick of pounding a screw driver into to filter but it still won't budge. I'm concerned that the filter may have some kind of locking mechanism. Since I so foolishly (stupidly!) put a hole in the filter I can't just fill up the crankcase and drive it to work tomorrow. Am I just not applying enough force or is there truly some locking mechanism?

I assume you tried a friction oil filter, or end cap wrench first? If not and you haven't totally distorted the filter try one of those first. If that doesn't work, then try a large pair of channel locks and see if that works.

Thanks! I actually did try those things but it still wouldn't budge. In the end, I had to drive a chisel through the filter and then pound on the ends of the chilsel for a full turn before the filter turned easily in my hand. Obviously, the mechanic at the Toyota dealership overtightened the filter or perhaps neglected to put a thin film of oil on the gasket before installing it. My new filter spun on easily and I made sure not to overtighten it. Before re-installing the skid plate I checked to make sure there were no leaks with the engine running. Everything looks ok and next time I probably won't have to remove the skid plate.

I hate when somone else changes my oil... it is very easy to overtighten the filter. I'm pleased to hear you got it off okay!

Wow, yea sounds like you had a longer than expected day.

Thanks for the heads up on the filter. Mine is due in about 200 miles and I always change it myself. I guess I'll allow a little extra time just in case.
