Hi all, I'm in the process of removing all the egr crap, and installing a non-egr manifold. I'm wondering if anyone can tell me if the three electrical/vacuum parts in the photo can be removed. What do they do? Will removing these cause me any grief? Thanks for your answers.

 

As long as you plug the line coming off the vac pump to the EGR stuff, you'll be ok.

 

Sweet, there gone!

 

10th post, yay. Yep, nix that stuff. Just make sure that your EPR (drivers side exhaust manifold) is in the open position, vac will shut it. Also, like Ram said, have vac go only to your climate control (runs in behind the fuel filter). Unless you live in a hippie-commie-liberal state, you should have no, zero, zilch, negative, none, niente problems with no ERG system. Enjoy!

 

Awesome!!! Thanks guys

 

More than likely the egr on the intake bridge is froze up anyway.

 

Yeah, probably. The previous owner really neglected this poor thing. Looks to me like he just drove it until it started having issues, then he parked it for who knows how long. Just doing the simple stuff like changing all the filters, adjusting the timing, and removing the egr crap has made a huge difference. Next will be the intake, injection pump and injectors. It's amazing how people use these things, makes me wonder how many diesels get parked in the weeds just because they didn't maintain them.

Does anyone happen to know if those nifty looking exhaust manifolds off of a military 6.2, hummer, will fit in a blazer chassis? I picked up a set cheap, and I'm hoping they fit. They look like they will flow better than stock.

 

They should fit the motor, but not your stock exhaust system. I'm assuming you're talking about the header looking manifolds. Have you thought about installing a turbo? I didn't at first, but the sound, power, economy, availability of parts, and cool factor have me convinced. That's the current project for my Blazer, a GM8 turbo with 4" exhaust dumping out behind the rear passenger side tire, so I can listen to the turbo whistle as I pump fuel.

 

Yeah, I've thought about the turbo. I am thinking about taking all the parts from a 6.5 in the junk yard but I don't know if I want to spend all the cash for that right now...but eventually I will turbo it!

 

I'd ceiling a 6.2 turbo budget to about an even grand, but I've seen people do it way cheaper. I wouldn't spend more than 150 on a used turbo (make sure it's not for a van, humvee, or dirtymax) because you might have to rebuild it. It's only about 90-110 bucks for the kit to do that, and amazingly simple. After that you'll need the 6.5TD exhaust manifolds, the 6.5 intake manifold and plenum, turbo-back exhaust, boost and EGT gauges, slightly turn up your injection pump, some mods to the A/C airbox (or swap w/ one out of an s-10), body lift is a maybe, rig up the wastegate, and make sure your giving the turbo oil and filtered air. That all seems daunting, but if you get the idea out of your head that this will be a one day project than it is very simple. I am getting all my parts piece by piece. I'm still hunting for the turbocharger I want. The local yards here both 1) will not let me carefully pull the parts I need myself, leaving it up to the guy with the torch, and 2) want to charge me GM factory pricing for new parts, though they're coming out of a wrecked (used) truck. About your junkyard, it's probably not a chain buisness, meaning prices are not set in stone. Point out a few other vehicles in his yard and say you're interested in "the axles in that truck" or "the engine in that (whatever) would be perfect for my next build." Chances are, he's probably been sitting on that 6.5 for a while. Offer him cash in hand (below what your budget is) and then talk him down. Hand him the cash directly and say "here, I'll give you $XXX for it right now." When/if he says no, politely (with your hand out, but within your personal space, where he'll have to reach) say "thank you for your time, but could you hand me my money back please." I've spent a few years securing a beach house in Hell by being a salesman and studying the psychology surrounding it. This has worked for mme and saved me thousands!
