I'm getting drips from this area at the top front passenger side of the engine. I can't tell for sure exactly where it's coming from, but it's somewhere around this part in the photo below. You can even see some of the oil drops on the floor beneath it. Anyone have any idea what here would be likely to be leaking, and how to fix it?

 

Valve cover gasket? The VTEC solenoid is right there too. They leak commonly, but I'm not sure they'd create that big of a mess.
What's the age & mileage of your car?

 

It's a 2002, 142K miles.

If the solenoid leaks commonly, I'm guessing maybe that's it. Do I need to replace it?

 

The gaskets at the very least.

 

Buy both:


And the DIY:

 

I'd also replace the valve cover gasket. The way the oil trails all the way along the head makes me think it has to be more than the VTEC solenoid gaskets.

 

Thanks!

 

Can be:

Vtec gasket
upper vtec gasket
tct orings
vtec pressure switch
oil light switch
valve cover gasket

 

Any suggestions how to troubleshoot the cause of the leak? Or to tackle them in a logical order that minimizes repeated work?

 

The last one on your list should be the oil pressure sensor. Do all the other ones as they're easy to replace and not expensive. Chances are you'll need to replace them all eventually might as well do it now and never have to do it again for 10 years.
