I have an 88 C1500 5.7 TBI with a manual transmission. The odometer reads 260k miles. I bought it a few months ago and have not driven it much. The previos owner said the engine and transmission were rebuilt by his father in law, so he had no paperwork, which makes me doubt that is true.
I don't know if this is normal, but while slowly going up my inclined driveway (not super steep), with the clutch pedal almost all the way out and the car barely moving, I could hear a knock. As soon as I pressed the pedal all the way on, the knock goes away. If I give I pump the accelerator with the clutch pedal all the way in, then I don't hear anything. But if I let the clutch pedal out to that spot where it is about to start moving or shut off if I don't give it gas, the. I can hear that knock again.
Is this normal or the early stages of the engine developing a knock? The oil was changed a couple weeks ago, probably haven't driven it more than 10 miles since the oil change.
Here is a video I recorded. When I say the clutch is almost all the way out, it is at that spot where the truck wants to start moving, but I have blocks in front and behind the tires.
