raviolli Posted August 16, 2013 Share Posted August 16, 2013 anyone on here ever bypassed their EGR? i know it could possibly make my cylinders run a little hotter, but anyone know if it'd be significantly higher? pros? cons?Ive got an '88 with a 2.5L tbi, and...well...funny story actually. i swapped in a 4wd ax-5 to replace my 2wd ax-4 and in doing so, i forgot to route my exhaust ABOVE the trans crossmember. (exhaust was unbolted at the cat) so instead of dropping the trans again, i decided to unbolt the exhaust from the manifold and re-route it that way. well...it is a jeep...so the first bolt snapped, and the second one rounded off before also snapping. in other words...'twas time to see what my lil four banger looks like without manifolds so i can get to these broken bolts. well my egr tube going from the exhaust manifold up through the intake and to the egr valve also broke. could just get a new one, but the end that bolts to the exhaust has a rounded off bolt that ill have to drill out, and the hole on the intake is completely stripped out. i think it was cross threaded. SO...for me to keep my egr...id have to buy a new tube, AND take my intake into a machine shop to have it reamed out, insert put in and rethreaded. or i was thinking of the simpler route and just deleting it completely since I'm thinking of getting a header. i would just put a steel plate over the hole on the intake manifold and for the time being (until i get a header), do the same to the exhaust Link to comment Share on other sites More sharing options...
kazam Posted January 16, 2022 Share Posted January 16, 2022 Greetings, I read your post and have some of the same questions regarding performance/functional changes if the EGR system is deleted. I have a 2.5L (1987). Anyone else have experience with the results of such a modification? Thanks. Link to comment Share on other sites More sharing options...
kazam Posted January 16, 2022 Share Posted January 16, 2022 I just found a similar thread: https://www.jeepforum.com/threads/egr-delete.2157009/ Thanks. Link to comment Share on other sites More sharing options...
omega_rugal Posted January 16, 2022 Share Posted January 16, 2022 plug the holes in the manifold and exhaust and call it a day... the engine will run better but it won't pass emissions so beware Link to comment Share on other sites More sharing options...
cruiser54 Posted January 17, 2022 Share Posted January 17, 2022 No downside. except emissions visual inspection maybe? Will run just fine. Link to comment Share on other sites More sharing options...
