This forum is specifically for exhaust system questions about any car. This includes catalytic converters, mufflers, tailpipes, hangers, bad smells, 02 sensors, smoke and possible drivability issues related to bad catalytics. The forum is NOT for modifications (See our new "Speed Shop" Board!!)or for engine problems....just from the exhaust manifold on back, folks! |

It sounds like a chopper, has no acceleration, & is killing us with carbon monoxide in the car when our family is going somewhere. A leak in the exhaust near the engine would explain the carbon monoxide coming into the vehicle. The chopper sound, too, is under the front end. What I can't explain, is the lack of power & how that correlates with an exhaust system. Am I on the right track? Should I let a pro tackle this one? I can do a few things, maybe. magilln

Replying to: Mr_Shiftright (Aug 04, 2005 7:39 am) If it were my van, and it were otherwise mechanically sound, I would just spring for a whole new exhaust system (from manifold to tailpipe). Again, this is assuming the van is in otherwise good shape, and you think it can provide several more years of reliable service. |

Replying to: 1racefan (Aug 04, 2005 7:53 am) The symptoms (exhaust in the engine bay, loss of power, sounds like a chopper) are classic cracked header issues. I know because I just replaced the very badly cracked one on my Jeep's straight-six (these engines are notorious for this problem). I knew it had a tear near the collector but it had another worse one higher up:  Look around the header as best you can with a flashlight, especially where it attaches to the engine block. This is not a cheap repair, though, but it's the labor and not the technical part that makes it so expensive, it's all grunt work. I was quoted $800-$1000, equally split between parts and labor, from the stealership and two different shops. I went aftermarket instead and picked up one from 1A Auto Parts for $160 or so, including a lifetime warranty on the part, and had a local boy-racer type install it (he did have ASE certification) in his garage for another $160 cash. Got it back yesterday and all problems are solved, I've got at least 20 more HP back and it's so very quiet now.
