AIB2C Head Cylinder Solenoid Valve Gasket 15815-R70-A01 15845-R70-A01 for Honda Accord Civic

First, this is a simple repair job. 2 bolts and the solenoid assembly comes off. Be aware that there are two dowel pins that hold the solenoid in place. It managed to lose both of them. However, they are just there for alignment which the bolts will also do once they are snugged into place. After replacing these gaskets I still had a very tiny leak. After about 10 minutes of running the motor, the leak stopped and it has not returned after over a month. I wonder if the gasket just needed to heat up for a few minutes to completely seal? Either way, this fixed the issue and was vastly cheaper than replacing the entire solenoid, which is Honda's only solution.

2012 Odyssey EX.146K. It stopped the leak but created another problem, poor idling and a permanent code no. P3497, check engine light on after it drove fine for few miles. Had to buy OEM front spool valve eventually. There is no way around it. All third party parts will fail 99% as per Odyssey forums

The gasket solved the leak but the unit failed when we put it back together. As it turns out, the pilot valve assembly is very sensitive to even the slightest over torque and the ECO mode will start acting up. I highly recommend installing the ECO defeat module, reduces oil usage and does not effect gas mileage. Do your research before you change out this gasket.

I think it has an issue even if I replace it and it still leak at the some spots must be it too think of the gaskets or my shim has a problem not shore so I replace the whole thing

This thing damn near ruined my Honda Odyssey just buckled and bought a new timing variable whatever for the oil stick. Do not buy.
