I don't know what your issue is. just for S&G I went ahead and called my local ford parts house and gave him the exact part number I posted for a quantity of four. this is what I got today.....i got the info from the parts bin and ordered 3 parts, the cdr valve, the hose to the valve cover and what i thought would be the hose/gasket to the air intake.
2 out of 3 were correct.
i posted the numbers in the "parts bin" years ago.
check out the tech articles...there's a shitload of info there. really.
E8TZ-6A892-A Retainer (rubber tube under cdr)
E3TZ-6A892-A Retainer (grommet that connects cdr to intake)
your point is?not to toot my own horn but...
