Hadn't heard from Sears about the rain check on the impact wrench. I called them and it was in. Drove 20 miles down to Eureka and picked it up. I've phoned all over about a 1 7/8" impact socket for the countershaft nut. Not sure if it needs one. But, it's rusty and left handed so it'll probably need all the help it can get. Got everything off the cam cover and it will come loose only enough to poop oil on the floor. Since I had done cams before and I studied the FM, I just whacked it harder and it came loose. What's that old phrase, "If in doubt, use a bigger hammer."
