Possible to bypass an EGR valve??

[MrAvant]

dilema.....

Due to go on holiday next week and the Kia Sedona Diesel is throwing out black smoke from the exhaust. The turbo is ok and i have a gut feeling that its the EGR valve.

Not enough time to have it replaced and we need the sedona....

Any help would be great.

Thanks

unbolt it, take a old coke can, flatten it out, take the gasket, trace it out on the coke can and cut the shape out but leave the port solid blocking the egr, bolt egr back on with your nice new blanking plate.

Thanks.

What i did already is just take the vacum pipe off.

Its seems to have cured the smoke and given me back some lost power.

The question is what are the implication of driving it like this?

You could always just clean if with carb cleaner and a toothbrush - if you can get to it.

if its sticking open removing the vacuum hose wont completely stop it, but it might be enough to get you by. side effects of doing away with egr is better mpg, more power, a cleaner intake and better reliability. downsides are worse NOx emissions, and some cars sense the egr is blocked by looking for a drop in airflow with the valve open and might put on the check engine light.

The car does drive much better with the vacum hose disconnected and thankfully no Check light on. It will only be driven approx 300 miles. It will take 10 days for the new one to arrive so i am not able to wait for it.

Fingers crossed the cars ok for the holiday.

Thanks all for your advise.
