I have a 87 F250 with a 302. Every time I drive it I smell like exhaust. Doesn't matter how short or long the trip, but the longer the trip the stronger the smell when you get out. I found 1 loose manifold bolt and tightend it, but no difference.
View 13 RepliesI have a 87 ford ranger pickup, it is running extremely ruff. You can smell the exhaust and it smells super rich and is even spitting fuel out of he exhaust. when I bought the truck the wires were cut on he oxygen sensor, so I put a new oxygen sensor in it hoping that it would lean out the fuel. The truck has duel tanks on it, but the back one is off and it is draining fuel out of the line when it is running. I don't know if the catalytic converters are plugged too, the truck only has 65,000 miles in it. or maybe its a vacuum line leak?
View 4 RepliesThe truck in question is a 93 F-150 X/cab 4x4, has 5.0 5spd. So yesterday i replaced my exhaust with pre made magnaflow "y" pipe/cat with a flow master 44 then new pipe all the way out. When i start the truck up this morning to let it warm up a little it started to give off a funny smell almost like brakes/electric burning smell. I was wondering if this is common for new pipes to burn off any oils that may have collected on them from the factory. I look under the truck and nothing is touching the exhaust, but the shiny new pipe is starting to change colors. So do you think it will go away in a short time? I have to an appointment about 30 miles away on the freeway think this will burn off?. BTW there was no smell prior to the exhaust change.
View 1 RepliesI have been thinking about toying with my exhaust. I don't have a crazy amount of money. I got a 94 F250 with the 5.8 liter 351. Heres what I was thinking. Get rid of everything after the cat, and then run a single 3 inch pipe from the cat to a flowmaster 40 series, and then exit either right before the back tire or right after it.

View 2 RepliesMy car has an exhaust smell coming into the car; seems to be from in front of the passenger side of the engine. Mechanic said it was from leaking valve cover gaskets, which have been replaced about a month ago. The smell is coming back and getting stronger. When I am in stop/go traffic, I have to open the windows. What else could this be caused by?
View 6 RepliesI have a 2008 6.4L F-250 and occasionally when I come to a stop I can see a faint white smoke coming out from under the truck and the hood. The smoke has a heavy diesel exhaust smell. When I step on the pedal nothing comes from the exhaust and it does not happen all the time. What is going on?

View 5 RepliesHow many O2 sensors does a 2.3 fi 4 cyl. have. I think just one on the manifold, but I'm not completely sure. Engine is running very rough and seems to miss at low RPMs, has no power and drinks gas like crazy!!! Emissions light is on on the dash. I'm thinking O2 sensor......tried replacing, but couldn't get enough torque on the sensor socket wrench to loosen, may be rusted.
View 6 RepliesI've owned this 1987 BMW since February, and after immense and expensive repairs, it became roadworthy. Recently there has been moderately high pitched hum coming from the Drivers side, approximately under the rear door area of the car. It seems to be coming from a part of the exhaust system(?). This part is white, vibrates, and is cylindrical in appearance.
The car only had one previous owner. He kept all record of the car over the year, so I know of no wrecks, repairs to the exhaust, and/or body work done to that area.
It is a menacing sound but doesn't seem to be affecting anything, and it only happens occasionally. I have noticed it mostly when idling, but it still occurs some when in first and second gear.
How to identify this part? I've looked through a few diagrams, but I am unsure. I need to know the importance of this hum, and whether I should seek a mechanic.
I tore it apart and there was no gasket or donut ring in the flange. Is there supposed to be a gasket or donut ring? I can feel the leak with my hand. I have retightened & it still "tick-ticks" real bad.

View 1 RepliesI have a 90 bronco with a efi 351w and im missing one nut for the manifold to exhaust pipe flange. I have looked all over the net and can't find the size I know its a 1/2in socket but I need the thread pitch and size, had the parts guy try to sell me the stud and nut kit seem really expensive for just a nut and to install the full kit I have to pull skid plates and the trany supports just to start to get room to do the job, seems like a lot of work to replace 1 nut...
View 1 RepliesI just purchased a 2003 V10 with 270 000kms. The truck had had regular maintenance. It has an exhaust leak and runs a little bit rough. Could the exhaust leak cause the truck to run a little rough or am I dealing with another issue?
View 2 RepliesMy F150 exhaust seems rather quiet when I first start it up, but after it gets warmed up good, the exhaust is much louder (which I like). I started wondering if I had a crack up front that widened out when it got hot, so looked under it when I got home today with it hot and still idling, but didn't see any cracks. Also I did not hear any noise like a leak. All sound was coming from the side exit pipe. So... what is the phenomenon that would cause this?

View 5 RepliesI am having an issue with exhaust coming from somewhere on top of the engine. I've been smelling it on start up for a couple of months and thought it was a rear window or door seal.
Well, with this (insert long string of expletives here) cold weather, I was having starting issues. Turns out all my battery terminals were loose-ish and a jump would get me going. Anyway, yesterday while getting a jump, once it started I noticed exhaust spouting from the top of the engine somewhere. With the engine fan and the wind, it was impossible to figure out where exactly it was coming from.
It has the stock boots on it (ordering from RR today) and the rest is in my sig. Stay warm! I did service the battery cables/terminals last night and made sure the batteries are charged. Im hoping for the best after work today.
Ok, probably about 1/3 times i start my 96 f150 4.9 with true duals, the left pipe has a higher pitched howling noise, its a steady tone whether I rev the truck up or not it just gets louder. It will do it for about 6 seconds and then stop. The truck doesn't run badly because of it, but i took her to autozone to get her scanned and they said that the oxygen sensor on the first manifold bank has a slow response on startup. Is that what causes this strange noise, I don't even know how it would make it, it sounds much different from the engine. The right pipe doesn't do anything.
View 9 RepliesLeaking exhaust manifold? The truck has a much louder than normal "knock" when accelerating. At first I thought and had some bad fuel in the tank. I eliminated that with a full take of good fuel and some STP but the "knocking" continued. Then I thought that perhaps it wasn't firing on all cylinders but it felt like it had full power. I took it to my mechanic and he said it as a exhaust manifold leak. He said that he has never replaced the exhaust manifold but that it was a "nightmare" and expensive. He also said that it's not a safety issue but on the long run the leak would cause the truck not to pass its emission test. He said the problem was with rusted bolts that would be difficult to remove.
