I have the axact same motor as your Sonoma series, and used your videos to help boost me in the right direction on swapping out with a crate motor from AutoZone. I have just finished completing the swap, and did everything like you did. Had a plugin issue at first startup. Found it, and corrected it. Finely got to the startup procedure,and everything went well, had oil pressure, temps looked great, purred like a kitten. Checked for leaks, and any engine noises. Nothing, everything seemed to be great. So I decided to take it for a spin down the road. Drove it about a 2 or 3 miles away from the house, down a back road. Gauges looked good. Pulled into a driveway and turned around to head back home. About a mile heading back, I get check gauge’s light, and oil pressure went to nothing. Did not move at all. So babied the throttle to get it home. Got home, and motor still sounded good. Couldn’t get a oil pressure gauge. So to rule out oil pressure sensor, I bought one, and put it in. Still no pressure, and now it sounds like the lifters are ticking a little. I’m wondering if the oil pump went bad. I would like to mention, that I did forget to prime the oil pump like you did, watched some other videos and primed through the drive shaft with a drill, since I already had the motor in the car when I thought about it. I just hope I didn’t screw this motor up, I do have a 4 year warranty on it. But no telling when I will get another one. All help appreciated. Daniel
