We Went a Little Too Hard.. Tearing Down LSXcalade's 427 To Find The Problem (Cutting it Close)

What happens here

After disconnecting all lines and cables, the presenter removes the intake manifold, noting that some hose clamps on the manifold side were difficult to reach during initial installation. He then inspects the underside of the intake manifold, pointing out an IAT (Intake Air Temperature) sensor and the brake booster connection. He mentions a regular hose clamp for the brake booster hose that replaced a factory clamp due to a previous incident where the original clamp failed under boost pressure. He then shows custom modifications he made to the manifold, including a drilled and tapped port for an extra port and a custom-made throttle return bracket.

Goal: Successfully remove the intake manifold and examine custom features.

Tools and materials

  • Allen Wrench — Removing bolts on the intake manifold
  • Brake Booster Hose — Connects the brake booster to the intake manifold
  • Hose Clamp — Securing the brake booster hose
  • IAT Sensor — Measures the temperature of air entering the engine
  • Intake Manifold Holley — Engine component that distributes air to the cylinders
  • Throttle Return Bracket — Custom fabricated bracket for throttle control

have not been touched in two years all right let's get this thing off of here I I think I got everything disconnected except this never mind yep all right there we forign a lot of these have hose clamps on the man manifold side that are impossible to reach with the manifold on so I have to clamp these on on the manifold side and then install it and do the actual um fastening on the other end of the hose this one here okay I think that's good boy all right that's a lot of stuff Dale so you see here um why does my engine bay look so clean well it's cuz there's all this other stuff that's all under here and you know makes it really hard to work on but it looks good when stun though case vent line the whole steam crossover all the injector harness all that runs under here second branch of the harness fuel whe return um it's good time to check these there's any chafing either all the O2 sensors connect back here the coil pack extensions like oh well there's so much room in here everybody says that I'm just like oh it's like that Meme of Homer Simpson whenever in the front he looks go but behind him is is all the crap like just so you can't see it that's that's what this is right here I'll show you what's going on with the intake manifold so you got i8 sensor back here this is where the brake booster goes onto you can see the stop clamp is still on here I got a C regular hose clamp there cuz the first time I ever had this out and turned with the Boost even past like 12 lb was atct Bristol the very first one I went to and I still had this Factory clamp on here well I turned the boost up and the first thing that happened was just blew this right off so me and my friend Justin had to go to Walmart and get a hose clamp that came with some like Prestone coolant flesh kit we was bought it just for the host clamp there's actually a video on that if you scroll back on my channel to August I believe yeah about mid August there's one is like from The Archives first time out street car Take Over Bristol that video is the very first time this thing ever came out and you can see some of this goofing around and how this ended up like that we fixed it on the side of the road and that's how this Factory clamp ended up up staying on there just kind of for fun one of those bolts end up staying in here cuz this this boss here makes it hard to get it out I had to drill and tap the manifold for an extra Port down there for that part and I made that throttle return bracket drilled…
