Have had issue wioth ;plugged nozzle mniost anytime car sits and yes that is more than should be. Alwaysd had not matter how much blow system down , top end lube or not. Actually worst with tope end lube. My brain kicked in and remind me of how use to check.

Wondering if anyone here has done same thing? We always blow down system and while ir hooked up we dbl checked BV leak. Most of time nozzles disconnected when leak testing. Accidentally found out leave it connected throw bv open. If number changes and drops one or more plugged. Back then I did this everhy week b4 loading car.

Anyone else do something close to? If give it a try let me know results too. Always good to get multiple results
