After using WD40 and rust dissolver, only one screw was able to be retrieved to remove the evap canister and purge solenoid from my vehicle.

The screw to get the solenoid off the canister will not budge. How do we find out what the screws/nuts are so we can get new ones and just replace both pieces, which don't come with any screws?

 

I supposed I should add this is for a 2003 Acura TL Type-S

 

Since you added that, I have moved this thread from the 1G RDX DIY & FAQ to the 2G TL Problems & Fixes Forum.

 

I had the same problem. I wound drilling out the old screw and then used a self tapping screw to replace it

 

I bought these screws from Acurapartswarehouse.com. They cost $0.62. The canister cost about $50.00. The screw inserts in the canister are metal and the canister is plastic. I was able to get one screw out and not damage the metal insert. The other screw was an issue. I got the screw out after grinding off the head and putting a pair of vise grips on the stud that was left. In the process, I stripped out the metal insert from the canister. No problem! Now that the insert was "free" (although unintentionally) from the canister, I locked it in my vise and proceeded to torque that stubborn screw right out of it.
OK. Now I sprayed brake cleaner in the canister mount for the metal insert to clean it out. Brake cleaner on the insert, too. Now that they were free from oil/grease, I dabbed some mix-to-cure epoxy on the insert and hammered that thing back into the canister. Waited 30 minutes for the epoxy to cure, and then installed the new canister vent valve (the thing that failed) onto the canister. Put the whole shebang back on the car. Total repair time: 90 minutes. EVAP code P1457 cleared after driving a short time.

Hope that helps

 

If you plan on working on JDM vehicles, I strongly recommend you get a set of JIS screwdrivers.

Long story short, JDM cars use JIS screws while others use regular Philips. It makes a huge difference (I didn't believe it at first either), but it has saved me from stripping some screws. Even saving one screw is worth it, because drilling is a nightmare.
