while checking out my car i decided to check vacuum. i tested 17 inches of manifld vac at a couple of ports, but at the port for the vacuum line that goes to the "T" for pcv i am only getting 10 inches. i cleaned both connections out and replaced the line to no avail. can these intakes and throttle bodies get that dirty inside? also how much vacuum should i be getting. i was planning in changing the intake man gasket anyway so now i will probaly spend some time cleaning the intake, T.B., and idle motor.

once again thanks for your time...dan
