So I changed my
oil for the first time with this new billet aluminum
oil pan. When I took the drain plug out and the
oil rushed out, I thought I had most of it out. It seemed like not very much, but the thought never occurred to me that the trap door in the center of the pan was holding back the oil from the other three chambers. The oil was flowing into the trap like it was supposed to, and not leaking out of the trap, like it was designed to do.
Anyway, with out thinking about it, I decided to take the pan off, just because I could, and I'd wanted to see the inside of the engine. So I pulled out all the bolts. To my surprise, that bottom piece of the pan felt rather heavy. It turns out, that the other three chambers were chuck full of oil, as was the center trap area. So basically I only drained maybe 3 quarts of oil from the drain plug, and there was about 6 more in the pan still.
I guess what I'm getting at here, is for those who have this new oil pan, when you change your oil, you may want to take the pan apart and get all of the oil out. Either that, or drain the oil when its hot, and let it sit for a few hour or over night, just to make sure you get all, or most of the oil out.
Imagine what would have happened had I not taken the pan off. I would have only drained 3 quarts, then I would have added 9 more to the system.
Anyway, call if you have questions.
