That's the plan tonight. Not to sound like an idiot, but free spin = bad, lock in = good.
And just to be clear, the problem child part is this one, correct? https://www.amazon.com/gp/product/B0042ORWNI/ref=ox_sc_act_title_3?ie=UTF8&psc=1&smid=ATVPDKIKX0DER
i replaced a bad check valve on mine and it stopped about half of the noise. then i replaced the solenoid, which didn't fix anything but i left the new one on. then i replaced the factory vacuum line with Napa vacuum hose and it fixed even more but not quite all of it. the final fix was a 2 part; 1) i added a redundant check valve right next to the original figuring how hot that engine bay gets and the cheap ass rubber diaphragm they put in those it would only be a matter of time before it fails again and... 2) dorman IWE replacement.

They come lightly coated with rollerball grease. I striped them down as much as i could, wiped the grease out and re-packed them with Marine greasehttps://www.amazon.com/Lucas-Oil-10320-Marine-Cartridge/dp/B005973H5Y
The whole system inst very big, are you getting at least 15" vacuum from the engine? does the solenoid work? its the check valve going in the right direction and does it hold at least 15"? are the lines tight? disconnected from the system using a vacuum test pump or smoke machine, do the IWEs hold vacuum?
