Yeah it dose sound a little noisy at idle when oil pressure is low, but when i give it a few revs or its under loads it sound fine. If the oils a thin grade or not able to take the temperature this may make it sound a little loud. Also keep an eye on your oil pressure gauge to make sure that it has quick response to revs and good oil pressure. Had my hole engine rebuilt about 8 months ago and only have about 3500kms on the engine and i still listen for every noise.
