CoolFlex hose blew off!!!!!
 

Coolflex hose blew off (upper radiator) and with it went a bit of the radiator neck!! It was on no tighter than the original Mazda hose?!?!. (Note: the aluminum billets were installed in accordance with the instructions to prevent this from happening in the first place). Well, I reattached it and now the oil pressure that I lost when it blew won't come back. Basically, I need some help/suggestions with both issues.

Thanks,
Brock
