Then one day on my way to work I blew th ereturn line from the oil cooler. Thinking it was just a leak and I could top it off and make it to work I was quickly proven wrong. Ended up heat seizing the motor. So in the middle of winter with no room in my garage my friend and I yanked the blown 4.3 and swaped in one from a '03 Sierra with just over 14,000 miles on it.
Worst part is, when I mounted the transmission I heard it clicked and continued to tighten the bolts. Even though it was seated I made the mistake of not turning it back to click again. I ended up crushing the pump on the tranny. Since I know nothing about trannys I sent it out for a nice rebuild for some heavy duty internals and a Corvette servo. Didn't want a shift kit, but the new servo does firm up the shifts a bit.
So nearly two grand behind my other mods would have to wait. But alteast I haqve a fresh new motor.
