exhaust fumes again

[wa5ngp]

I need to figure out how to post a pix cause it looks ridiculous now. I had an old truck exhaust system in my junk pile. It had huge chrome tips. I sawed off the end and it is jammed up into the turbo muffler end and sticks way out about a foot. I'll clamp it lightly so I can remove it.

We'll see what happens to the smell now.

My Z started showing the exhaust issue back in about 73, so I didn't think it was the seals on a 2 yr old car. Eventually, someone convinced me to have an extension made which bends to the side and directs the exhaust into the air flow along the side of the car. It has worked ever since. The car has the original exhaust except for the rear muffler. I am thinking of getting a new extension made which will look a little better than the old one.

Then why do i,with a 36 year old car,who's tip is flush with the bumper have no issue?

This means that you're saying every Z car had this issue.

I did not say that but, you can if you want. Of the four cars with this problem I have worked on all four were cured the same way. Entend the muffler outlet pipe..

I did not have this problem with mine for years. I had to replace the muffler and then it took a year to figure out where the smell was coming from. My stock muffler had a chrome tip on it the replacement did not. Replaced the tip and no more problem. It could be as simple as the location of the outlet on the muffler itself.

This could be due to various causes, and possibly not if they don't apply:

1) You're a smoker and aren't sensitive to exhaust smell. No flaming intended, just an observation that since I quit smoking my sense of smell seems better.

2) Your job at the railroad exposes you to stronger fumes than what you smell in the Z and therefore don't notice it.

3) The humidity (or lack of it) in your part of the country (AZ) creates different effects. In the NW with all the moisture, we get moss and mildew, and they can smell pretty strongly, yet some people don't notice it. I'll bet that you might notice it.

4) As Jim mentioned, the location of your muffler tip in relation to the bumper and other items on your car may be affecting the air flow around your car such that the exhaust isn't a problem for you. Maybe you have larger mirrors, or larger mud flaps, or larger tires, or you don't drive with the windows open, all those are possibilities.

The end result is that just because you don't have the problem as stated, while other people and cars who have had that problem have found this solution works for them, is no reason for you to deny that the solution is correct for them.
