New to the group. I have a 2010 CR-V . 135k miles just bought it. Right after I start it almost instantly it makes a grinding noise for 1-2 seconds then goes away. I replaced the VVT solenoid. Still making the noise maybe even worse. It only does this on a cold start. After the cars been running it will not make the noise. Usually takes sitting for at least 4-5 or more hours to make the grinding noise. Oils been changed a few times so it’s nice and clean. What is making the grinding noise and how do I fix it.
