Just recently changed the Timing chain and the tensioner on my sr20det s14. the cam never made this noise before i changed the timing chain. I though it was a defected timing chain and tensioner so i changed it again with a new one but it didn't make a difference, same result. I'm getting good oil pressure nothing below standard. and i have checked the lifters and have changed them still the same problem.
after the car warms up the noise goes away same result when i have the rev at about 1500 rpm no noise. i thought about taking the cam apart to see whats going on inside but wanted to see is someone else has had the same problem with the intake "vtec" cam on a sr20det S14/S15 before i did anything else
