Nissan CA/RB Timing Belt Cover Washer/Grommet

thingiverse

This is a custom-made rubber gasket/washer for the timing belt cover on a Nissan RB25 engine. Replacing the old one can be done with minimal effort and cost. Many users online confirm that this replacement part also fits perfectly on the CA18, RB20, RB26, and VG30 engines. During my experience, I noticed that the original rubber grommet/washers had become brittle and some of them broke apart when trying to remove them from their mounts. In order to get a good fit, you need to carefully clean up the old metal washer before inserting it into the printed replacement parts. I chose to print this part in TPU (NinjaTek Cheetah) for its superior flexibility and durability.
