I must be going crazy!!! I decided that I've been paying way too much to have my oil and oil filter changed on my '97 F-150 4.6L 4X4 truck (w/ oil and transmission cooler). So, I go ahead and buy the oil and filter, then drain the engine oil. Then I spend the next hour looking for the oil filter. I can't find it anywhere. I crawl around underneath the truck, in the engine compartment, look in every nook and cranny, but no oil filter. Finally, after it starts getting dark, I give up and refill the crankcase with fresh oil (with the old oil fitler).
Any ideas would be appreciated. I feel like an idiot.
