I am getting ready to perform a full egr cooler delete from First Coast. I ordered my modified manifold with the EGR valve orifice left open "unwelded". I plan to reinstall my EGR valve and plug it in to retain the stock appearance.
My questions:
I originally planned to weld the EGR valve shut to avoid any possible opening under WOT as I've read some do. Since I am completeley removing the up-pipe that feeds the valve and installing a blocked off up-pipe, is welding it necessary?
Is there a way that the smog guys can "test" if the valve is functioning during the smog test and know that it is welded, if indeed welding it is the way I go?:rofl:
Everybody be careful. This guy is a tool. He has no problem bashing you on an open forum if something doesn't go rite. This guys an idiot. He just needs to get his thing together and keep moving to another forum.:thumb:
But in short, it keeps your EGR cooler from leaking coolant into your exhaust and intake and burning coolant in the engine, which could ultimately if dirven too long could ruin the motor.
The EGR cooler fails from the mulitiple reasons. Oil cooler goes, and takes EGR cooler with it, Excessive idling will overheat the cooler, and performance reasons, Higher EGTs and higher exhaust drive pressure, will pop the EGR cooler. SO the EGR delete is to stop the gasses from getting to the intake, and eliminate the coolant from getting into your motor where its not supposed to be.
The EGR cooler is a POS, and will fail, letting coolant into the intake, and eventually taking out your headgaskets. Just a crappy design from International
