SMALL oil leak from VTEC solenoid area?

I cleaned up my JDM H22 really well before putting it in, so spotting any fluid leaks would be easy. Well, I'm glad I did that, because there is a very small amount of oil right below the area where the VTEC solenoid and VTEC presure sensor are. I know the cam seals on B-series engines are notorious for faliure, causing similar symptoms. . .does the H22 have this problem also? How are the VTEC solenoid and pressure sensor sealed from oil leakage? ANy other suggestions?

Hell yes. Things to look for:
- Oil pan
- Rear main
- Front main
- Cam seals
- Dist seal
- VTEC solenoid
- Balancer shafts
- Valve cover
- Valve cover donuts (plug holes)

I think that's about it. The solenoid is easy to get to and the rubber is cheap. I'd go ahead and do the dist one as well, and the rear passenger's cam seal (can get to it w/o removing the cam). Other than the oil pan and valve cover, the others are tough enough to get to that unless they are a big problem, just do them when you do a timing belt (or clutch job, for the rear main).

I think the only items you mentioned that are anywhere near my area of concern are:
  • Dist. seal (I removed the distributor to rewire it, so it might not have re-sealed correctly)
  • Valve cover gasket (removed valve cover to replace the leaky plug bore doughnuts while installing engine
  • VTEC solenoid seal (never touched it)
  • Cam seal

I don't leave any puddles on the ground, and the oil level hasn't gone down since the swap (or course, it's only been driven like 10 miles). My first guess would be the dist. seal or valve cover gasket (since I recently removed both of those). Guess I'll just replace the solenoid seal and cam seal at the same time.

I wasn't indicating that I thought these were your source, merely that they are the "usual suspects" when it comes to leaks.

Generally the problem is not that things don't seal back up, it's that the seal deteriorated. As the rubber ages and is exposed to repeated thermal cycles and heat, it hardens and can crack. After maybe 100k miles or 10 years, just about all rubber is pretty well shot. You can't trust it, at least, and I would recommend replacing all of it.

My guess is the VTEC solenoid if that's where its leaking. I'd go ahead and replace all that you can get to since you're talking about $50-$75 in rubber from hparts.com, max.
