My thinking on it. At 2,200 to 4,000 rpm. He should have about 50 ~ 60 psi. That maybe what is needed for the VVL and Varivalve timing to operate there. Not enough oil pressure and things get noisy. Once he goes past 4,000 rpm, oil pressure goes up, and things quite down. He may have enough oil pressure to operate everything above 4,000 rpm's. Might have just enough of a leak to cause an issue between 2,200 and 4,000 rpm's. If I'm right. He maybe be catching it before the real damage starts. Won't know until he mounts an oil pressure gauge.
Remember to get one that reads from 0 to 150 psi.
