Default Disable EGR

Hi! I have a 2.2L 93 Camry. I couldn't find this information so could
anyone please tell me how exactly can I disable the EGR system? Is it
enough just to unplug the hoses?

Thanks,
Erhan

Dont do it keeping exaust gas in the oil will ruin oil shortly, plus
your car wont likely run right.

Umm, why would you want to disable it? If you're in a state that mandates
vehicle inspections, it would never pass, for one thing, and secondly, your
car won't run right if you do. So why?

EGR = Exhaust Gas Recirculator. It takes exhaust gas from the exhaust
manifold and runs it back through the intake. Nothing touches the oil.
The idea is to cool down the burning fuel by introducing an inert gas,
which in turn reduces NoX emissions.

To disable, one needs to unplug the hose to the EGR diaphragm and plug
the hose. Doing so will increase combustion temperature (enough to
cause damage? Beats me), fail emissions on NoX and result in a
Check Engine light.

The first response is getting EGR confused with PCV. PCV (positive
crankcase ventilation) removes blow by gases from the crankcase
by running them through the intake. Most cars require that extra
air/gas to run right. My cars idle real rough without their PCV.
