Locate an Exhaust Manifold Leak on a 460
Although the sketch of the 460's exhaust manifold remained the corresponding throughout its Industry, there were variations of its fasteners. Some manifolds used isolated retaining bolts, while others instead featured studs and nuts. With either diagram, both types of wrenches are chief to remove the fasteners. Appliance the open-end wrench to access the fasteners that the socket wrench cannot access. For this grounds, a inexperienced gasket should be installed straightaway.
Instructions
1. Remove the exhaust manifold's securing nuts or bolts with a socket wrench and with an open-end wrench.First off produced in 1968, the Ford 460 used a yoke of one-piece exhaust manifolds to frank the engine's exhaust gases to the exhaust pipes. Between the cylinder sense and the exhaust manifold is a gasket designed to prevent exhaust leaks. When the gasket fails, regularly a puffing sound can be heard as the exhaust gases leak away of the manifold. Besides repeatedly than not, on the other hand, the anterior comment of a manifold leak is the enduring odour of poor exhaust gases inside the vehicle.
2. Pull the exhaust manifold off the cylinder tendency to access the manifold's gasket. Tap on the backside of the manifold with a rubber mallet to dislodge it provided the manifold is stuck.
3. Peel the exhaust manifold gasket off of either the cylinder intellect or the manifold, depending on which surface the gasket adhered to. The abundance of the gasket which failed can be identified by a clouded burn site.
4. Position a virgin exhaust-manifold gasket onto the manifold or, provided the engine instead features studs, slide the gasket onto the studs and against the cylinder head. The 460's exhaust-manifold gasket is self-sealing, meaning that gasket sealant must not be applied to the gasket.
5. Place the exhaust manifold against the cylinder head, then tighten the exhaust manifold's fasteners to between 30 and 35 ft-lbs. of torque with a torque wrench.
