Hi guys! New user and a lucky (?) owner of a Savana 1500 with a 350 Vortec. First of all, since English isn´t my mother tongue, I apologize for any misspellings and whatnot. Anyway, I´m currently working on the vehicle which my family and I are going to use as a "holiday-car" during this summer and, hopefully, many to come. As of now, I´m in the process of replacing the intake gaskets (got the Fel-Pro ones as a replacement) but I am struggeling somewhat with the EGR-tubing.
After a great deal of hassle, I realized that the fitting on the intake manifold wasn´t going to come off, even though I´d soaked it with rust-spray, heated it with a blowtorch several times etc, it was just stuck. I ended up cutting off the EGR-tube by the intake manifold as well as by the exhaust manifold and now it is finally removed (the fittings as well, even though it took me a great deal of effort to remove the nut from the intake...). So, I was just thinking...is it really necessary to order a new tube a re-fit it or could you just "plug" the holes in the intake as well as on the exhaust. I would obiously use some hardware with proper threads (emission control here isn´t that thorough, so they would probably not raise any voices), but would this sort of operation interfere with the PCM or other bits?
I would in that case still have a EGR valve fully connected, only without the actual tubing. Would it work? If so - better or worse than before? I am not searching for any sort of mpg or hp benefits, just want a solid trustworthy vehicle....what do you say? Is it worth shelling out a 100+ dollars for a new tube or should I try to just block it off...(without any PCM tuning or likewise)?
Again, sorry if I am not explaining things right or using an excessive amount of words to get to my point. Hopefully, you´ll understand anyway.
Thanks in advance and best regards from Sweden!
