Replacing the Purge Valve pulled my fuel trims back in line and resolved my poor idle issue. I should note that the poor idle still existed. Set the oxy-acetylene torch to its lowest level of heat, and place the tip of the silver solder against the crack of the damaged exhaust manifold. Use a size one tip solder and place the torch very near to melt it onto and into the crack. This is a low-rise model; the port exit dimensions are 2.

You'll need a couple of wrenches or deep sockets to remove the manifold. Not only that, leaky coolant will also cause air from the outside to get into the engine through the seal.

While a crack is easier to detect, gasket issues are harder, so before you do go unbolting your manifold, just take a quick look at the vacuum lines and component that are connected to see if the issue of pressure is not sourced elsewhere. The intake manifold is attached to the top of the engine by the intake manifold gasket, which has to be monitored as it is susceptible to cracking under the heat and pressure and allowing coolant or oil to escape. There is a great write-up in the tech section about using a timing light and a vacuum gauge to tune your rig properly. Emery cloth or some very light grit sandpaper is perfect for this, but we've found that a small scraper works best, especially in tight confines. To look for a crack, look closely at the manifold, particularly where it bolts up to the motor and where the most heat will be. If you see any leaks or signs of a poor intake manifold gasket, get it repaired immediately.

Although your intake manifold could be the source of your engine troubles, it might not be the only component you need to take a look at. However, most exhaust manifolds are made from cast iron, and there are limited ways to mend such items. The exhaust smell may or not be noticeable from the interior of the vehicle but will be more noticeable in the engine bay and the areas around the manifold. The vacuum draws gases emitted by the pistons that are then burned with the fuel and air mixture. On smaller-displacement engines in front wheel drive cars and most engines in rear wheel drive cars, replacing a leaking exhaust manifold gasket is quite easy. Once you recognize this, you can proceed to fix the problem without wasting any more time.

There is more rwhp and rwtq to be made with aftermarket cylinder heads vs. This cast aluminum alloy model is for single, square-bore 4-barrels, with a power from idle to 6,000 rpm. If you see this, then it means the seal will not hold and will be susceptible to leakage.

And there is no permanet fix for this problem. You can pick up these scrapers from Home Depot or Lowe's. Intake manifolds fail because of the high levels of constantly-changing heat and pressure they are subjected to on a daily basis. Epoxy adheres accurately to a rough surface as opposed to a smooth one and as such, the area should be sanded down properly at least 2 inches from the site of the crack. Patrick Murphy rejected the Dex-Cool class action by ruling that the magnitude of the class action, combined with the wide array of state laws involved, would make it impossible to cover all claims under one national class action.
