Oil leak around VTEC spool valve

It's not leaking anymore since I replaced the gasket. But ever since I replaced the gasket, it's been throwing that error code when running at highway speeds. Until it finally stopped working entirely.

I didn't replace the solenoid, only the gasket to fix the oil leak. I'm going to replace the entire solenoid assembly and change the oil this weekend and report back if still having issues.

Replaced the solenoid today and all codes are gone. Engine is running normally now.

Hello, sorry to resurrect an old thread, but the P3497 for bank 2 has crept up again. I cleared the code and it drove fine for a few weeks, then it came back again today. The front VTEC solenoid was just replaced 2 years ago but I don't drive a lot since I work from home, so it doesn't have a lot of miles on it.

Oil was just changed a few months back; says it has 70% life left. It has been cold this winter, could that be the cause of the low oil pressure? Or could it be the quality of the oil? I did have to use a cheap oil last change due to cost, but I did get the OEM Honda filter.

So far, the CEL hasn't come back on, but it seems to be sporadic. I'm not sure if it's just the cheaper oil combined with low temperatures, or if the VTEC solenoid is having an issue. But the solenoid is only 2 years old with barely any mileage on it so I'm not sure. I've read that poor quality oil can cause this error code as well. Should I change the oil again with a higher quality and see how it goes?

Yes it's full and still golden colored.

I'm in South Carolina. It's been down in the 20s at night and recently the teens. But most times when I go to drive it's in the 30s at least. I don't know if the cold is making the oil thicker and can't build up pressure quick enough? I hope the VTEC solenoid isn't failing it's not that old and I don't drive a lot.

I'd have to check if it has warranty, I got it from RockAuto.
