Ford F-150 - 1997-2003 :: 1999 - Gasoline In The Engine Oil?
Sep 16, 2013
newly rebuilt 1999 4.3 liter engine in a 1997 truck.
The truck fired right up. After 15 minutes of running, we shut it down and checked the oil. There was a slight white milky fluid in it. I drained the oil which produced more milky fluid. I suspected anti-freeze.
I poured this into a one-gallon oil container and let it sit for a few days. A friend of mine opened the container and immediately smelled gas in the oil.
He mentioned this could be a vacuum issue allowing unburned gasoline to work it's way back into the oil.

With my windows up I occasionally get a slight whiff or smell of gasoline with the engine running. Doesn't matter if A/C is on or off. I crawled all under the truck and can't see any fuel dripping. (2005 5.4)

I own a 2003 Hummer H2 with a 6.0 liter vortec engine with only 62,000 miles. At 50 to 55 mph 1500 to 2000 rpm the engine surges 300 to 400rpm with foot steady on the throttle. There is no engine light on and I,ve checked for codes with a code reader from the auto parts store. No error codes. I've cleaned the mass flow air sensor and throttle body with no change. My next thought was to replace the throttle actuator control sensor or accelerator pedal position sensor. I do enjoy working on my own vehicles so have been reluctant to take it into the shop.

My truck is leaking behind the engine. There is not any coolant on top of the engine. It's leaking above the transmission and running down the passage sides. Are there any hoses that could be leaking behind. Sometimes it leaks a lot other times it doesn't leak at all. The shop thinks it's a freeze plug but wouldn't it be leaking more if it was?

1999 4.6 (106K miles) will stumble / miss when at 35-50 mph under a mid throttle load (just before reaching the downshift point). Has been doing this since I bought the truck at 70K miles.
Computer has no codes, engine runs fine under all other circumstances, and gets a decent ~20 MPG on the highway.
Done the standard tune up items (plugs / motocraft) and cleaned MAF, replaced TPS, tranny flush/ filter. Replaced the left O2 sensor 2 months ago, but it dumped a code and was really noticeable when it went out.
I am about ready to dive off and replace the MAF, but at $100 a shot would like other alternatives to try first. I am really convinced the engine is leaning out and misfiring under this load.

i have a 1999 F-150 2x4 witha 5.4 liter v-8 with 151,000 miles. Last week the truck began to run rough when i accelerated (ideled fine)and felt like it wasn't fireing on all cylinders and was puffing white smoke. A few minutes later the battery light came on and the truck lost all power and shut off. I replaced the battery and alternator and everything ran fine for a week. Now the issues have come back but i'm not sure the alternator and batter have gone bad again. What could be going on? Have the coils gone bad?

I own a 1999 F-150 V6 4.2 and would like solving what sounds to be a chirping noise coming from the engine. Noise is pretty consistent at which occurs at first startup while in park, drive or reverse and definitely every time I hit the gas from a standstill. The noise is pretty faint but bothers me just enough to where I want to ask the experts. Anyway noise began roughly days after I washed down the motor. I sprayed some degreaser on it and was very careful - making sure to cover the fuse box, alternator and high flow k&n intake air filter.
I stayed away from cables and just used a garden hose. Recently I had the lower idle pulley bearings replaced, serpentine belt and alternator. When I took to Ford for a new belt (it was old) and to inspect the chirping noise, they said # 6 spark plug was loose and that was the reason for the chirp (they called it a ticking noise). First of all how does a spark plug just come loose? They hand tightened it back and I drove the truck for less than a week then the noise was back. Any possibility this sounds like something specific that is wrong? My research says that it could be anything from the belt tensioner to the cam sychronizer to the heat shield around the cat converter.

I have a '99 F150 w/ the 5.4 and 4R70W, with 226K miles. I am experiencing what I believe is a TC shudder after the tranny shifts into OD between approximately 40-50mph. This sounds like a pretty common problem with this particular tranny, but some of what I've read describes the shudder as feeling akin to driving over rumblestrips, but what I'm experiencing is a very sharp, bucking. Is this how the TC shudder feels, or am I actually dealing with a misfire. Btw, I did completely change the tranny fluid with Mercon V, and added a friction modifier, but no change. I also read that the TC unlocks when the brake lights come on, so I tried lightly hitting the brakes when the bucking was occuring, but it continued.

Engine will start and run but will miss in a pull and die sometimes but will start back, we hooked it to a scanner and it said (intake wiring) it wasn't a dealer hook up just a gas station garage, we have already done plugs and wires.

How does one get to the top mounting bolts to engine? Are special tools required? Is there an access plate?

I have a 1999 F150 4x4 5.4, I pulled the heads due to blown head gasket. Prior to pulling heads truck started and run fine other than miss on #1 cylinder. I timed the engine according to Haynes manual and posts on this site. Truck is now hard to start and idles very rough. I does seem to smooth out when reving the engine and seems to have plenty of power. Cant find any vacuum leaks or unplugged wires.

My '03 Tacoma Prerunner V6 has 116K miles and recently lit up its Check Engine light, returning a code for a failed up-stream air/fuel sensor. I recently drove across country, using many different fuel formulations ranging from CA gas to midwest ethanol to whatever they put in the gas here in the NY-NJ area (a mystery ingredient that seems to turn motorists irate and confuse their horn as a turn signal.)Anyway- age, or fuel, what killed the sensor? If fuel, will it happen again by time I get back west?

My trucks symptoms include a illuminated service engine soon light, sometimes a high rpm idle, and sometimes a rough erratic idle. When a scan was done it indicated the oxygen sensor was defective. The issue is: which specific one (there are multiple oxygen sensors) or how could I check or determine the faulty one for sure. I am trying to economize and replace only the bad one myself if possible. I own a good multimeter, can it determine the bad one? 1999 F-150 4.2 Litre V6 oxygen sensor dillemna....

I have a 99 f150 with the 4.2l v6 with a 5 speed 173000 miles. I picked it up not to long ago. When I first got it it had both the P0171 & P0174 lean on bank 1&2 it was also siting for a while. I replaced the fuel filter which was filled with black fuel, also changed the PCV valve, cleaned the MAF sensor, and changed the oil. I cleared the code, drove it for a little bit and the light came back on after 20 miles.
I then proceeded to replace the upper and lower intake manifold gaskets. Upon doing that i noticed that i was missing one of the linkages for the IMRC. I went to the junkyard and pulled off another linkage rod off the same motor. ordered new plastic clips, put the IMRC on cleaned everything up and began putting it back together. I also cleaned the Injectors while i had them out as well and put in new spark plugs and wires.
Put everything back together. code was cleared since the battery was disconnected. drove it and then the engine light came back on again. this time it was only the p0174. so i then both the upstream and downstream O2 sensors on bank 2, reset the code and it came back on again. I'm lost.

I have just finished changing head gasket. I started up the engine works fine. But I hear a little clik sound form the converter. I put it in gear, but it can't move either forward or backward. It ran 2-3 liters of oil out of the converter when I took the engine out. I have filled new oil in the gearbox but not in the converter, dosnt it came form the gearbox into the converter?Is there air in the converter or what's wrong?
it is a F150 4x4 4.6 1997 automatic.

My husband drives a 97 Toyota Corolla. Great little car with one problem, it stinks. It smells like gasoline after its started. I never smell it from inside the car, just after its run when I exit the car. Took to a mechanic.... they couldn't find a leak and of course they didn't smell anything. He told me the LEFT OUTPUT SHAFT SEAL needs to be replaced but wasn't very positive that had anything to do with the gasoline smell. He only suggested replacing the gas cap, again, not with much confidence. Should I take it back, take somewhere else, anyway of narrowing down the possible leak areas myself or other suggested areas for them to look for the leak???

My wife has an '03 Ford Expedition with 110k miles on it. It began dying while driving. Sometimes while moving. Other times when stopping or idling. She would describe that sometimes when it began acting like it was going to die she could "give it gas" and it would revive, other times that wouldn't work. It would usually restart after one or two tries. Our local mechanic did a tune up and replaced a coil. During the trip she began hearing a sound of "metal shredding" and the car died and wouldn't restart. She had it towed to a ford dealer. They replaced the IAC valve.
After that the dying would continue but instead of dying right away it would "lose acceleration, and eventually die within a few seconds" Took it to another ford dealership and they replaced the fuel pump and relay. It would work fine for a few weeks and then start dying again. Another local mechanic noted the error code P0231 "Fuel Pump Secondary Circuit Low" He kept it for a few weeks and was able to get it to die for him once but not again. The dying continued. Sometimes it would work great for weeks, other times it would die continually on the same trip. Took it to a 3rd dealer and they couldn't find anything wrong.It dies in the cold and in the heat. Usually after driving at least 20 minutes into a trip. Once it dies once it will typically continue to do so until resting for a day or so. Sometimes with a full tank of gas, sometimes with a low tank.

1997 200 SX SE coupe. It has the 1.6L engine and is a 5 speed.
I recently purchased this car and it had the CEL or check engine light on. The part store stated the codes were: P0304 X 2 and P1445.
Here is my problem that occurs mainly once the engine is warmed up- it started bucking and hesitating whenever I push the gas pedal. It doesn't do it when the engine is cold- at least it is very slight and hard to notice. On the highway at constant cruising speeds the car rides and purrs great. While I'm idling at a red light the rpm is constantly dropping about 100 rpm every second.
I have tried the following:
-Replaced distributor cap. The cap was slightly corroded.
-Tested spark plug wires by applying then to metal and looking for spark.
-Did a dry compression test and all cyl ranged from 150-160 psi. (Good levels??)-
-Sprayed carb cleaner around manifold to see if idle changes - nothing
I am fairly a novice at mechanics so I'm still learning. Perhaps the car has stale gas? Not sure how long it has sat, or even if it has been sitting. bad injector? Bad fuel pump/ filter?

I have a 97 Geo Metro two door that just stalled on me one day driving up a hill. It was low on fuel and so I thought it might have just ran out of fuel. I put more fuel in it but it would not start. I had it towed back home and disconnected the hose out of the fuel pump to see if any fuel would spray out. It did not. This lead me to conclude the fuel pump is bad. I replaced the fuel pump but this still did not fix the problem. I had an electrical guy looking at it run a bypass wire to the fuel pump and it still did not work. His conclusion was that the ECM is bad. Does this sound like a logical conclusion?

Almost every time I start my 2001 Ford Focus, it won't start. The starter functions but the engine won't start. I have to pump it, give it gas, and once it starts, it's perfectly fine, no stalling, no problems after that. That is until I turn the engine off. When I go to start it again, say after doing an errand or two, it may or may not happen again throughout the day, the problem only occurring when I attempt to start it.
