EGR Tube

Since I am keeping all emissions and keeping the motor stock (for now). I needed to figure out the EGR Tube. This tube basically takes exhaust gases from the manifold and send it back into the intake to be re-burned for a cleaner exhaust/emission. Many delete this as putting dirty hot exhaust into your engine is not something most of us can imagine. However, if Ford and all other Mfgs do it and engines seem to last, I guess it isn't all that bad. :confused:
In short the stock tube needed to be extended to the front of the engine. Also had to have clearance for the engine mount, the oil filter/cooler and make a sharp turn into the fitting on the manifold.
So how to solve this one. First the Terminator has a very good exhaust manifold and from reading different articles performs pretty well considering what it is. The manifold is flipped so the opening is at the front of the engine. The manifold had a treaded compression fitting for the EGR. It is an odd tread and fitting not easily found, so I used the fittings for both ends of the original EGR tube. I also got a second EGR tube donated by jcurti2 to help with the extra bends and to have a backup for the just in case. The EGR tube is stainless steel 3/4 tubing. I also used a section of the donor Fuel Vapor Return line which was the same size SS tubing. My brother helped me cut up the pieces and fit the jig saw puzzle together. We got it all rough cut and ready to be tack welded to fit perfect. Problem was I don't have a TIG welder and renting one was not going to be cheap or easy. Ugh, another problem to solve.
Thanks to a great FFR community. I put out a plea for help on the other forum for a TIG welder in my area. By the end of the day I got a response from Stage7 (Roberto) who responded to my thread. The following Sunday he came to the house and TIG'd up the EGR tube pieces I had rough cut. Stage7 had his work cut out for him as the OEM tubing is not a nice mandrel bend, more like a triangle. He did a great job considering. All he asked of me was to provide a bottle of gas. Oh and the best part, return the favor and work on his RCR Superlite. :) Thanks again to Stage7, great guy with some great welding skills and new car buddy.
Here are some pics of it all. It is now ceramic coated silver and has a heat barrier. Another problem solved.
