#415 of 874 Ratpatrol, Post #412 ----- Eventually This Odor Will Not Be An Issue With The 4Runner
Nov 10, 2003 (4:42 pm)
Keeping you old F150 and picking up either a BMW Z4 or a 2 year old Boxter is not a bad trade off.
From what has been written on this forum, some people never experience these odors and others complain of the smell all the time. I would rather buy a truck that never breaks and find a solution to this only problem.
I spoke with the owner of a detail shop about his experience with his 04 V6 Limited 4Runner. He pulls a 3000 lb. boat with ease. He is very satisfied with this truck. He traded in a 2003 Dodge pickup and really took a beaten, he did not say how much of a loss but said it was substantial. The Dodge had some quality issues, so far his Runner has been perfect.
I asked him about the sulfur odor. He said when he accelerates hard with the back window down he gets an odor only one time, after that he has no problem. He went to a muffler shop and they advised the fix was to cut the tail pipe and replace the tip with a curved pipe that diverts the exhaust to the side. Cost was about $80.00.
This is the same fix that others have suggested in this forum. I agree that Toyota should repair this if it is a real problem.
I have decided that if I experience the odor with my new 4Runner, I will not wait for a recall or a TSB to correct it. I will either try the $80.00 fix or most likely have the Borla system installed which also is side exhaust.
Has anyone had their exhaust diverted to the side to correct the odor problem? How well did this work? Where did you have it done? Cost?
I do not believe, for the money, there is a better midsize SUV on the market then the V6 or V8 4Runner. At this time, I will never consider anything other than Toyota/Lexus or Honda/Acura products. I have had costly experiences with other makes and I do not believe they are anywhere close to Toyota or Honda quality. Just look at resales. When my new 4Runner arrives I will sell my 2002 4Runner (have it presold) Sport Edition with 37,000 miles for $24,500.00. Two years ago I paid a little over invoice, $31,259.00 for this truck. I do not consider this a substantial loss. And a dealer would sell this same truck certified for around $28,000.00. Try getting that value out of a two year old domestic.
My truck may not arrive for a month. After I break it in, I will post if I do or do not have an issue with the sulfur smell.
#416 of 874 Long-term exposure to CO
Nov 10, 2003 (5:22 pm)
rcgator, my understanding of this hazard matches yours. CO is not toxic in the ordinary sense, it's just that it binds much more tightly to the hemoglobin in blood than oxygen does, displacing the oxygen that keeps the brain alive. If the CO exposure is temporary or slight, the blood concentration of CO goes up for a time, but doesn't get high enough to be a problem and it eventually falls.
That's why the treatment for acute exposure (high CO concentrations in the blood) is a hyperbaric chamber, where the high partial pressure of oxygen can drive the CO out of the blood much more rapidly than at normal pressure, preventing further damage.
As a practical matter, of course, it's undesirable to have much exhaust get into the cabin, even if CO is low. That's why Toyota's choice to place the exhaust outlet at the back of the vehicle instead of the side continues to be a puzzler to me. They're an engineering-driven company and usually have a reason for what they do, but I can't fathom it here.
#417 of 874 CO is toxic because it binds the hemoglobin
Nov 10, 2003 (7:55 pm)
it binds it like cement in a drainpipe. hemoglobin is pretty good about releasing oxygen to cells, and taking up CO2 and releasing it in the lungs... but when it gets sludged up with CO, it is very difficult to get it to release the poison and take up either CO2 or O2 again. best results for CO poisoning are received when the patient(s) are locked into a decompression chamber that is overpressurized with medical oxygen.. and left there for a day. HCMC is the only hospital around these parts with a hyperbaric chamber for the purpose, it holds 8 patients at a time.
it's pissy nasty stuff. you don't want any if you can avoid it.

For what it is worth. I have been having the horrible smell INSIDE the cabin of my V-6 2003 4-runner since day one. I have tried every manufacturer of gasoline and every grade of gasoline within 50 miles and the problem still occurs. In addition, these stations are in the reformulated section of the country. So lets hear some more about how gasoline is the problemÖ
I have never been in a vehicle, other than this one, that you could smell your own exhaust while driving. Can one of you car salesman or service managers on this posting tell me how this happens? Notice I didnít say problem, since Toyota thinks this is NORMAL for a vehicle and not a problem.
Windows up or down it doesnít make a difference.
To bad the only thing that is ever going to resolve this issue is class action.
#419 of 874 You're going to get laughed
Nov 11, 2003 (5:19 am)
at if you approach a lawyer with the only proof being your own nose and statements from people on an internet chat board.
To initiate a class-action suit, there are several stages - without solid evidence, the first couple of stages will not happen. The final stage is getting it certified by a judge, where the suit is allowed to proceed. Won't happen without more that idle gossip.

I bought my Runner from the dealer with the Borla dual side exhaust installed at the factory/port. I have noticed on rare instances the sulfur smell. The smell can be induced. Just stomp the gas pedal from a stop with the rear window down. But, I do not have a lingering smell problem. Not enough of a smell problem to start a vindetta with the dealer or Toyota. So, in theory, the dual mounted side exhaust works. Before you spend $$ with an 'ambulance chaser', I would check out Borla. You can buy the dual Borla for about $605 and it can be installed easily in your garage using a 14mm socket wrench and rubber mallet. Or, any local exhaust shop can install it in their sleep.
#421 of 874 Anyone Installed The Borla Exhaust System To Solve The Problem?
Nov 11, 2003 (6:09 am)
Has anyone had the Borla Exhaust System installed on their 03 or 04 4Runner? Did this eliminate the sulfur smell?
And has anyone had the exhaust pipe modified to exhaust to the side? Did this eliminate the sulfur smell?
Any other fixes -- different gas brands, catalytic converter replaced, dealers repaired something else?
If a simple fix like modifying to side exhaust or replacing with the expensive Borla system solves this problem, maybe Toyota will use this information for an eventual recall.
Nov 11, 2003 (6:23 am)
$605.00 to install yourself is not bad. Plus you have the benefit of additional HP and Torque. You stated in a previous post that this added more power?
This may be one solution, probably diverting the pipes to the side will also work.
Nov 11, 2003 (7:43 am)
Well, Borla claims there is an increase in hp and torque of 10%. I can say the system has IMMEDIATE throttle response. I don't recall my test drive with a non-Borla OEM V8, so I can't compare to what I have. But it sure sounds nice and the 'punch' will definately push you back into the seats similar to the Cobra SVT that I used to own.
Price of $605 was found by another member in another 4Runner forum.

Driftracer, why are you on this message board? Please show me one posting of yours where you have contributed anything to the discussion except the Toyota is wonderful mantra?
Unfortunately you are right with regards to class action. Itís not worth the effort.
I guess that is why most people feel like the only form of life lower than a lawyer is a car salesman (or the associated service manager.)
