I have a 2010 Silverado 1500 with a 5.3 that has 260,000 miles on it. It only uses 1 quart of oil in 6000 miles. My question is how long can the injectors go and what would be the symptoms of them needing to be replaced?

There is no specific life time for any component in an engine. I would keep doing exactly what you are doing. Whatever it is, it's working.

I guess I don't see the correlation with fuel injectors and oil consumption, but 1 qt every 6K miles doesn't seem terribly for that mileage.

out of curiosity, first tranny or rebuild?

Given that many manufactures now a days say that 1 quart every 1000 miles is acceptable- I think you're doing pretty good.  The injectors are doing well, but who knows when they will start to give out.  Some go at 70,000 miles, some may go a million miles.  Put some $$$ away each pay check you get dedicated to your vehicle be it repairs or a replacement vehicle someday.

Guys have been telling me they've done injectors on '17-'19 trucks with less than 7k on the clock, so consider yourself lucky. They do fail regularly on the '07-up trucks, and usually will cause rich codes, rough idle, and hard starting. At that mileage, you could be on the 2nd - 4th set.

 

On a modern vehicle, injectors would be the last thing on my mind at that mileage. For starters, you're probably 60% through its 2nd replacement engine & transmission, and the rear differential should be close. The front end, if you live in the Northeast, has probably been overhauled 4 times (or much more) so far. Not to mention all the electrical gremlins that usually pop up much, much sooner, especially if you live in the rust belt.

If that's actually the OE engine, you'd better play the lottery!

That is the original engine only thing I have done is 2 sets of spark plugs, 1 set of plug wires and oil and filter changes.

Yours is the very first 5.3 in a 900 series that I've ever heard of making it even remotely close to that far, without major valve train repairs.

 

You bought it new?

It was my work truck and when I retired they gave it to me. The truck looks and drives like the day it rolled ohh the lot.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
