    Need some Advice on Engine tear down

    I'm tearing the engine down to the block. I wanted to know if there's anything worth replacing while I have the heads off. I'm currently replacing the stock lifters with LSX performance lifters from ZZ performance and the pushrods with hardened chromoly push rats from Texas speed. I'm also going...

    Is there such a thing as front shocks for a Z55 Denali that aren't going to cost me all the gold in FT. Knox?

    Hey B-train, I am in position where i'm being offered a set of 2019 tahoe complete front strut assemblies. I would be placing them in my 2007 Denali. when you put yours, did you need to modify anything other than the adding of the resistors? do you know if they's work with the existing auto...

    That helps tremendously! You say the ground is at the black of the head? As for the bad fuse block, will it be in the fuse box? Im new to the truck platform. Its my first big truck.

    Still having misfires on bank 2, need some help

    So, my bank 2 Cat died and caused a whole mess of issues. Misfires galore on 2, 4, 6 and 8. So had the cats replaced and then replaced plugs and wires. Cleared up for a bit and then began having misfires on bank 2 again. Did a smoke test, because i figured I had air intrusion and found the oil...

    All bank 2 cylinders misfire

    Ok, I have an update. First, I'm pretty sure I don't have a FM. The plate underneath the intake manifold doesn't look "lumpy". I posted a pic of the plate as best I could take. Next, I hooked up the smoke machine and I'm getting a ton of smoke coming out of my oil fill tube extension at the base...

    All bank 2 cylinders misfire

    I'm right and around 106k maybe 107 k. I checked all the wiring and it was intact. I'm not too sure on the maintenance I just bought the truck about 10 months ago and it had around 97k. I've only changed the downstream on the bad cat side. I'm planning to change the other three this weekend. I...

    Catalytic converter help...

    That is definitely a good question. I was wondering the same thing myself but I think that some stuff did make it down into the muffler. Either way, it's an excuse to buy a new muffler!

    All bank 2 cylinders misfire

    I only changed the down stream on the passenger side, which was the destroyed Cat. I also checked all the wiring for the injectors and coils. The wires were intact. But, I just slapped the scanner on the truck and I got a new trouble code, p0174. So apparently I'm not showing a lean condition on...

    All bank 2 cylinders misfire

    Hey there! So I'm going to need some help and I'm hoping I can find it here. Here's the background, I was driving home on the expressway and I started getting a flashing check engine light and I know I had misfires. I hooked up the skin tool and found that the entire bank 2 cylinders were...

    Vigor air ride shocks?

    Update, I've had the vigor air shocks installed since about march. They've been holding up just fine and I have no issues whatsoever. No leaks to report and they ride very well. So far so good. I wish they made them for the front too...

    Not sure what I have in there...

    I've recently replaced my rear shocks and now I need to work on the front. I'm not sure what's in there now but I took a picture and it does have a resistor connected. So I'm assuming I don't have to run air shocks in the front now? But if I can get some opinions, it would help tremendously...

    Catalytic converter help...

    So here's the back story. I was driving home on the expressway and suddenly start seeing the flashing check engine and I'm feeling misfires. I had my scan tool with me so I plugged it in and found out I'm misfiring on the entire Bank 2 cylinders. A couple days before I started hearing a sort of...

    Lifter Squeak!

    My truck actually does not have AFM, which is a load off my shoulders. I believe it o ky has the VVT. I'm debating on whether I want a stage 1 or stage 2 cam at this point. I want a solid daily driver and I don't really want a choppy idle. I do plan on re-ising the stock rockers, as long as...

    2013 Tahoe LS P0300 code

    Sometimes you can tell if you have no compression by listening to the exhaust. sometimes it will sound like you've added a cam. It happened on a yukon i was working on. It sounded like it was cammed. from there, we pretty much knew what it was. the compression test confirmed an issue. it ended...

    New Member from Illinois 2011 Yukon Denali, love it but where is the power?

    Did you happen to run a VIN check before your purchase? I've been looking to upgrade my fleet with an escalade and have noticed that a lot of people are turning back odometers. This is in Chicago by the way. I would try an confirm that your mileage is accurate. From there, i'd have an exhaust...

    Need some help...

    I'm replacing my head gaskets and while I'm in there I'm going to replace the lifters and push rods. Can anyone confirm the stock push red length? As far as I can tell it's 7.400" unless I'm incorrect of course. I have the L92 without AFM. As always, Any help is greatly appreciated!

    Updated valve covers

    I'm new to the big body SUV ownership thing. I have a 2007 Denali with the 6.2L engine. I've heard a few people tell me that I need updated valve covers and I'm not too sure what they're talking about. I believe it has something to do with PCV location. I would love to get some information on...
