the honda one is like 5bucks just get a new one change it out it takes all of 10mins, and be done for another 4years while your thier change everything again. i just bought a top-end gasket set(with head gasket) for 54bucks.

the str has like 3-4 o-rings to stop oil from leak where as the honda is just the plastic, str is better. but for 5 bucks every 4 years go honda.
