SOURCE: replace expansion valve
The only expansion valve that I can think of that you may like to replace is on the air conditioning unit....This valve is found usualy mounted onto the AC unit....You'll have to remove the dash board and centre consul....This is qute a job....You should then see the expantion valve on the cabin side of the AC housing....where the pipes go thru into the engine compartment....NOW HOLD EVERYTHING.....before you can remove the valve you need to depressurize the AC unit....That should be done by an expert....The gas is dangerous and you must wear safety googles at ALL times....Once you have removed the valve, you must seal the system so that as little moisture as possible enters the system....If it is left open, you'll have to replace the dryer unit too....when you've finished your replacement, assembly is the opposite as disassembly.....You'll then need to have the system recharged....Don't try to engage it until that has been done....It wont work even if you tried ,as there are pressur switches which will inhibit the opperation....If you have had practice, it will take about three quarters of a day......if not, three or four days
Hope that this helps you

It should be on the valve cover. It should b "L" shaped and inserted into a rubber grommit and connected at the top is a vacuum line.

Sounds to me like you have either forgot to put back on the breather tube that runs off of the top of the valve cover, or, you did not set your valve cover correctly, or the torque is not correct on the cover itself.
8.7ft/lbs and the torque sequence is inside to outside (torque the inner-most nut between cyl 2 & 3 first, then the one above it then alternate sides on the outside ones). Recommended Hondabond is on the corners and the cam cap areas.
