can I block off the egr and run it that way..?

but the port from the intake doesn't seal off the vacuum?
please explain, this. more details.

the port in the egr that comes from the intake manifold does not seal when the egr is closed. so it has a vacuum leak through the egr (where exactly is this LEAK)


the 1995 had 2 systems used, early and late seen here,, part ID 50 is missing it is early 95. (what I call the quad port)

https://fixkick.com/EGR-Gen2a.html

it idle and not moving the car, 0mph there is no vacuum ever past the VSV valve.
hose 16 is ported vacuum "P" at idle The TV in the TB is closed and there is no vacuum to the hose 16.
the nose 16 and 19 /22  are dead if engine not hot (180f coolant) car not idling, (and not moving) the EGR only works moving hot engine, over 0mPH.
then opens and ported vacuum lands at modulator 8. (using cat back pressure to see engine load)
if the cat is not missing or hose 13  missing or mpt cracked, then part 8 , sends vacuum to EGR MAIN #5 opens, and opens based on CAT back pressures, (then at WOT, the vsv closes)
hose 13 is exhaust back pressure , is what I call the bark tube,  #4 exhaust only Putt Putt Tube. this does the modulation. IF THE CAT IS DEAD so be BARK SO BE MOD SO BE EGR.


late is yours. edited

if any of  this fails DTC 51 happens. (if you just unplug hose 23 and put screw or golf tee in the end , EGR main stays closed and stays that way for ever. code 51 full time.
