Well, changed my oil, checked all the fluids and this noise is coming from the power steering pump area but i dont think its the power steering pump, i think its a lifter. But it makes me think because its not a constant noise, could it be a oil pump going bad, i really dont know but here is a clip of the noise.



Please help me out, i hope its not too bad, if so i guess my build will start sooner than i thought.

Thanks in advance.

so ive heard a rod knock, rod bearing so far, only reason i thought oil pump as a possibility is because it comes and goes. It's so wierd. I thought a rod knock would be more of a constant thing.

to me that sounds like a rod bearing.. sounds like the piston hitting the head. I would tear the motor down. Oh, and when oil pumps go bad.. they dont make noise.. if you tear one apart and see how they work. you would see why they dont make any noise.
