Subject: Re: EGR theory and high flow exhausts by bogus on 2013/6/14 4:48:06 Bob - It's funny, but the ports on the intake, tho black and gnarly, are usually ok... it's the bends around the valve that get coked up. Counterpoint, tho... Honda engines back in the 90s had issue with EGR. They used a rather high-tech solution for EGR injection; these little 1/8" diameter holes that ran above the intake runner. They would get coked up and clog. There were two fixes... one worked on the I-4's, and that was to drill out the casting riser, and drill the tubes clean. The other option, and the only fix for the V6, was to remove the intake and hot tank it. |
