Review on AUTOKAY VTEC Cylinder Head Solenoid Gasket 15815-R70-A01 - High-Performance Gasket for Honda (15815R70A01) by Christopher Lott

Installs these again in October. It seemed to work fine for several months as I regularly checked the valve for leaks and it was sparkling clean. But now maybe 5 months later I have a fairly significant leak which I hope doesn't blow my generator again. In just a few months, they roughly doubled in size, causing the leak. My advice is to stay away from them and order an OEM control valve assembly and remove the OEM seals from that part. Those aftermarket gaskets may seem like a great deal, but they cost a lot when you have to repeat repairs and potentially fry the alternator if oil seeps onto/into it. If you've read some of the comments in the YouTube video for this repair, you'll see that other people are also commenting on these seals failing. I usually stick with OEM parts because you almost always get what you pay for. Unfortunately, there were no OEM replacement seals available other than purchasing the entire spool valve assembly. So I took a chance and they failed. Not very surprised. There are very few shortcuts in life.
