Review on 🔧 MITZONE Upgraded Yellow Aluminum Valve Covers (Front & Rear), Compatible with 2002-2009 Nissan Altima Maxima Murano Quest Infiniti i35 VQ35DE 3.5L… by Juice Jali

Spend time disassembling and cleaning the inside of the covers under the plastic baffles. There's a lot of aluminum filings in there. If you don't want this in your oil, clean them. If you have high lift cams (12mm+) it will hit the baffles. You have to crash against black plastic and screws. I used a small rotary tool with a barrel grinder attachment. If you use outdoor cameras you should be fine. Luckily I spun my crank by hand to see if it hit. It was like this. A pair of screws are inserted directly into the recesses of the deflector. Be careful.
