i been told by many people that it dont harm the engine. even the mechanic at my local hyundai dealer said block it off, it helps the engine breath clean air instead of its own S**t, plus helps turbo spoll up quick which is less turbo lag. the egr on i30 is electronic and runs at the back of engine from turbo. FRom my experiance the car runs smoother , alot quieter , and alot more torque and power. people have different opinions regarding egr valve. But when my local hyundai mechanic says block it , that said it all for me. i used coke can as tempory shim just to see if it caused any warning lights. and it hasn't... if you do block your egr valve block from exhaust side not the valve itself, and leave valve connected to loom. then it wont bring up any faults cos ECU thinks its still doing its job. Thanks guys i will keep you posted if i get any fault lights come up
"knocking" in a direct injected diesel?
EGR blocking is common on many makes, I believe Hy use a different term for similar technology but I DONT see any Threads about poor "EGR" performance / failure on this site.I had a new EGR on my last car, a Fiat Grande Punto, 1.9 MJet, at around 50,000 miles as it became completely choked / blocked & the solenoid operation plunger had seized with soot. Many Fiat owners ask about & discuss the advantages / draw-backs of blocking off the EGR. Bottom line is that there is no performance or economy benefits over a fully operational EGR, however, if there were issues related to a partly ineffective EGR then blocking i off MAY seem to improve things. In reality, he EGR provides a cooling effect on the incoming charge for combustion as well as reducing the NoX content of a modern diesel, probably the same for a petrol engine with an EGR... Some schools of thoughts suggest blocking the EGR may be detrimental to Turbo life....
That would be a very good & informative test. I'd love to close mine off too, but not on the strength of other people's opinions, something more scientific is required.
I see quite a few fans of this concept on the site.. I do wonder though, if there are no downsides, why it is not like that my default
Hi XamaxyWhat exactly did you gain by blocking the EGR..?
