Hello, If someone could give me some advice that'd be wonderful. I own a 2014 Chevrolet Silverado 1500 5.3L and im purchasing a straight pipe/standard exhaust converter. the converter requires a vacuum line to tap into, anyone have any ideas? thank you

What?

 

There are basically zero vacuum lines on these engines. The only two lines that go into the intake are for the PCV system.

 

You can't run a vacuum line down to any part of the exhaust, that would create a vacuum leak and to be honest I have never heard of an exhaust converter needing a vacuum line.

its a converter from ECSTuning. they are designed for European cars but the universal system in the link works with any vehicle if it has a vacuum line you're able to tap into so you can swap from straight pipe to regular exhaust in the press of a button. https://www.ecstuning.com/b-ecs-parts/build-your-own-universal-vacuum-actuated-exhaust-cutout-kit-single-cutout/020923ecs01~dk/?pdk=AAAAAQQEAQ

So it's a cutout, not a converter.

 

You can run a vacuum source down there from the brake booster line. You should be able to find a "T" fitting with two large nipples and a smaller nipple so you can run a line down to the cut out.

Im having problems with locating the hose behind the manifold because I’m having that same problem on my 2017. Where exactly is that hose connected to?

I cleaned mine and then ran a 4gauge wire with it because I have a Rockford fosgate power 1000watt and jl 400 amp, and clean the one under your alternator, and driver side wheel well to

The hose is a transmission breather vent along side of the transmission, the other one is a ground next to the mud flap, and another one on the driver side same position

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.

      I can't believe that could possibly be the case. It should be 36mo/100k miles from installation. Then again, it also seems like since a dealership installed it, it'd all be in the system and you wouldn't need to worry about registering, either. Shows you what I know. 😄 Hope this one outlives the warranty!

      I haven't seen inventory recovery from COVID.    In the few random times I 'build my own' truck or SUV, no one has the exact one I want.   GM has been working to lower incentives too for a long time.    A $500 incentive isn't getting me off the couch to go truck shopping.
