tick tock, no clock
car: 1973 Dodge Dart Swinger
engine: stock 318 with 2-barrel Carter problem: I am hearing ticking, but not valve sounding, more like exhaust leak. It increases with High speed/rpms. Question(s): How do I located the problem (sounds like driver's side bank)? If the manifold is cracked, what are my options? If it is a gasket, well that shouldnt be too hard. If it is the down pipe from the manifolds to the y-portion of the exhaust, well then what? thank you ahead of time people. caesar |

Hey caesar;
This is allways a pain. To help and try to locate the problem while the engine is cool, do a visual check of the manifold(s) area. Clean well with solvent and brush if need be. Start engine and run your hand around the area under suspision. (SP sorry) If you can not feel or see anything, grab a water bottle with a spray trigger. Like an empty windex bottle, just add water, no windex inside. (ECK!) Spray (steam) around the area to see if the water runs down or gets bubbled/blown away from the mating areas of the exhaust, or if idle goes up on the intake. If you find a pipe cracked, a muffler shop can handle it easy. If it's on your own, you can try to weld it or prep for surgery and cut out the bad length and graph in a replacement tube. A replacement Y pipe isn't ever cheap, but probably the best thing to do. |

Could it be the heat riser? They can get noisy.

How many years has it been since heat risers were used? I'm guessing since FI and computer controls for fuel and ignition. Maybe the TB was the beginning of the end for the HR.

True, very true. Seeing that I can't leave stock alone, and usally hotrod the rides to some extent, that part is lost.
On headers, I end up without it or custom bend tin to fit a tube. |
