Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Greetings and Welcome to Just answer.
Does the knock change with engine speed? what I mean is this, does the knock get worse with engine speed or does it stay the same?
OK, Does it sound deep and near the bottom or light and near the top?
What does it say about the oil pressure?
That will depend on the damage to the crank and rods. YOu will have to inspect and see for sure.
If you pull the pan, replace the oil. It really does not matter with a stock application. Factory will be just find.
these motors do not do well when they starve for oil. The bearings damage quickly, It would be more cost effective to either get a good used motor or a reman motor
for a used motor try www.car-part.com for a reman try jasper engines
