If you’re familiar with the BMW E46, you may already know that they are notorious for leaking oil. As of the time of this post, E46’s on the road are 15+ years old, so most of them will experience oil leaks to some degree. The most common oil leaks on the E46 are at the oil filter housing gasket, the oil pan gasket, and the valve cover gasket. On this particular post, I will be covering the valve cover gasket replacement on the BMW E46, which will apply to all BMW 323i, 325i, 328i, and 330i models.

One very common issue on the 4th generation Toyota 4Runner is an oil leak that occurs at the front corner of the passenger side valve cover. Changing out the valve cover gaskets on both passenger and driver sides can be a bigger job, but mainly because it can be a bit overwhelming with the amount of parts you need to disconnect or remove. Therefore, it’s very important to be organized when removing parts and to document everything you take apart. Photos along the way help tremendously in guiding you to put everything back in the right order. I hope this guide helps you if you need to replace the valve cover gaskets on your 4.0L V6 (1GRE-FE) 4th Generation Toyota 4Runner.
