As the subject point out I have a 2007 cadilac escalade with a 140K on the clock and I am starting to get what appear to be a VVT system failure. I am prepareing for the worst as I have not tried to read the oil pressure on a scan tool yet since I can not get it on dash. As much as a cam gear assembly, cam valve, cam magnet, chain and all the gaskets cost plus the amount of labor I am thinking about just buying a pullout engine since I have already thrown alot of money on this engine's oil leaks and other problems. My question would my ECU know the difference if I droped in a L94? I am not trying to add AFM to the truck it is just that L92 are a lot harder to come by with low miles since they were not in a very many trucks compared to the L94. I figured the AFM vavle rests on V8 mode and my ECU would not know what to do with and just plain ignore it. Are my assumptions correct? Either way I need the truck to last another 60K and just want to spend the extra money for piece of mind on a 40k pull out. Hell I even thought about removing the VVT and getting the ECU tuned with out it.


Also at this point I would not mind putting a 5.3 if it would work, just depends what is available locally.

Dealer time.

With the quotes I have seen for this job, no way. It is over 10 hours labor which could put upwards 2K which is damn near 50% of a pull out.

Big question is can I replace the valve through the timing cover? from my diagrams it apears to be open once the magnet is removed.

Been working on engines for years, and this is the first I've heard of a "WT" system ...

 

With that in mind, I'd find another engine WITHOUT the fancy, failure prone parts, install it, and be on my way. Just my .02 ....

I think he meant VVT, as in variable valve timing.

      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.
