For those of you who have the NBS Silverado/Sierra.

 

I need to go through the firewall or down through the floor with some wire. I would prefer to go through an existing rubber grommet or if I ABSOLUTELY have to, drill a hole. I have not yet looked at the firewall <-- I'm lazy. But when I last had the hood open I had plenty of space in the engine bay. Like a ridiculous amount of room to mount stuff yada yada yada.

 

The wire I am running through the firewall is maybe 1/4" thick. I just looked under my dash near the passenger side and didn't see a whole lot. I'm sure there is more room near the drivers side.

 

Just curious as to where you guys went through at?

there should be a huge rubber grommet that the steering column goes through. i poked a hole in small hole on the side of the grommet. I put about an 1/4 inch amp power wire through it and it works good.

I looked into that option, and mine is a very heavy duty thick rubber boot. I don't feel comfortable going through it at all. Instead ive found a couple of paths to go through the front drivers side fenders from inside the cab. I really had to look hard to find it.

Any suggestions on how you found this route? I need to run a speaker wire for a siren to the engine compartment and I don't want to drill another hole. I already have a good size one drilled for my other accessories. Any help (or pics if possible) would be great.

      I'm suborn like that Ed. There's a plaque in my doctor office that says, "Don't quit, take a break." Works for allot of things.    Reality is, the wife loves her SUV and even given it's issues, she'd buy another if she found one with low enough miles. Then again she has me to maintain it.    Most of what ails this thing is GM shooting themselves in the foot and by extension the buyer. Besides a ridiculous breather system the cat warm up strategy, IMHO, is the dumbest thing I've ever seen an OEM do to a vehicle they warranty. On cold start it r-e-t-a-r-d-s the ignition to like -17* ATDC and dump fuel like kicking over a pail to force combustion in the CAT's for rapid warm up. This literally hoses the oil off cylinder walls and creates enough varnish precursors to stick rings in even well maintained engines. THEN if that wasn't bad enough they recommend using a wanting fluid specification at equally stupid interval.    Common to all GDI motors I'm aware of is this silly practice of driving the HPFP off the cam giving a leaking pump direct and unchecked access to the crankcase. And sir, eventually the ALL leak. Your job is to "catch it if you can". Yes, these are the same people that removed dipsticks from engines and transmissions in belief Joe Average wasn't capable of checking, reading and maintain his own vehicles fluids. Sadly  and in large they were correct. Most people these days can't tell a sparkplug from a fire plug.  Great ideas one and all.    Every move and every error calculated to defend themselves from the law and their own customers.

      Most online suppliers and Amazon. All have noted "not for use with Bose speakers".

      Very interesting thread. Definitely didn’t expect to see this kind of mileage out of that engine.

      Just did an injector/HPFP replacement on Pepper at 192,400 miles; close enough to 200K, RIGHT? (If 200K is considered life end and to me it isn't). But hey, to each his own.    Have never run a catch can on this vehicle. Back side of every valve looked like a new valve spray painted semigloss black. Port walls looked 'neat' (all a normal result of passive EGR via VVT) Zero build up even in AFM cylinders. Just color. It uses no measurable oil and never has.    At 155,000 I put her on E-85 and a borescope of the cylinders at plug change showed very clean pistons and valve faces. The replaced injector tips looked new. (It was the pump piston seal that was leaking). Oh well, have six good backups.    Still gets 28 mpg on gas (highway average) and over 20 (highway) on alky. UOA's look good and runs as good now as it did when I bought it. Better in fact.    What improvement would a Catch Can provide this motor?     And given all this I expect that IF I installed one I'd see some water/gas/oil vapor accumulation. Byproducts of normal combustion.   Having said that, IF my motor used an appreciable amount of oil I'd consider it a useful 'crutch' until I had the situation corrected OR if bore polished, until I junked it or rebuilt it to stave off repeated plug fouling.    I'm not telling you what I THINK. But what its DONE.

      Love the look. I'm a SCSB lover myself.    Two items. 1.) A spacer changes scrub radius but this also changes when we use wheels of different offsets. A little isn't a big deal. 2.) Steel wheels, alloy wheels all have different thickness. Same effect on the stud and lug nut as a spacer. When hub centric the wheel isn't supported by the stud. It's supported by the hub. The stud just keeps it all together.
