I replaced the intake cam gear seal on my G37 using an OEM seal from Z1 Motorsports, and the experience was exactly what you want when working on critical engine components.
The seal itself is high quality and built to OEM specifications. Fitment was perfect, and installation was straightforward with no issues. It seated properly and provided a clean, secure seal right away. When dealing with timing components and oil control, having parts that fit correctly the first time is essential.
This is a small part, but it plays an important role in preventing oil leaks and maintaining proper engine operation. It’s definitely not something worth reusing or replacing with lower-quality alternatives, especially when you’re already in the engine doing timing work.
Z1 Motorsports delivered as expected—fast shipping, well-packaged parts, and everything arrived in excellent condition.
Overall, I’m very satisfied with the quality of the seal and the purchasing experience. If you’re doing timing service or addressing leaks, this is a simple but important part to replace, and Z1 is a reliable source for OEM components.
