Review on Fel Pro VS 50770 Valve Gasket by Casey Tatum

The gaskets fit perfectly on the rocker covers on my 2008 G35 with VQ35HR engine and prevent oil leaks causing alternator failure. The o-rings that I assumed were for camshaft position sensors come in two different sizes and only the smaller of the two seems to fit the CPS. My CPS o-rings didn't leak at all and they're pretty easy to get to later, so I didn't want to risk replacing just one and remembering which one later, so I just didn't risk using those in this one Sentence. I haven't had a terrible leak in the spark plug tube either, so I decided to just replace the gaskets and reuse the rocker arm caps as they are hard to find and expensive to replace. Be careful when removing the rocker covers as they are plastic and can tear and prepare RTV silicone tubing for the front corners of the cover/gasket. I've been using Mobil One synthetic oil since I bought a used car with 80,000 miles and the camshafts looked brand new with little to no wear. You can also consider spark plugs and an intake manifold gasket. So far no leaks for a week or so! My new alternator loves it dry!
