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.

      Some Assembly is Required

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.

      Gas Prices

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
