Message The Gaskets are there to seal them while they are moving ( However Little ).. Yes Gaskets will degrade over time and Distance Moved..
Also.. Things are never flat.. and if the gasket was not squished in that area because of some minor warp.. it will start leaking..
I like to look at the O2 Sensor Voltage to tell what my mixtures are doing.. Wideband is even better.. as better resolution..

I was chasing an Upper Intake to Lower Intake leak on my '95 NA a few months back.. Could not find it.. Built a fixture to be able to pressure check the lower to head/Injector area..

I slathered a little Non Hardening Permitex on the Surfaces on the last assembly.. no Problems.. so something was a little off..
