I was checking my COPs and the first one I pulled out of my 2002 f150 5.4l had a clearish liquid on the coil boot. I looked down in the spark plug hole and it was filled almost to the top of the spark plug itself. I smelled it and it smelled like gas. Why this would happen and what should be done to fix it?
View 3 RepliesThis a 02 with 5.4, had codes po306, pulled and checked sparkplug had moisture in it. Fixed that ran ok for a little bit then started again, no codes now and smells a little like rotten egg.
View 1 RepliesI have a 2001 ford f250 6.8 v10 with just about 183,000 miles on it my wife has been driving it and she told me it was running kinda rough so I took it for a drive and she was right so I pulled #1 COP and found it was full of oil and the same with#2 and #3 had a little bit of oil not as bad. What is causing my plug holes to fill with oil?
View 14 RepliesI purchased a 2000 F250 SD with 5.4L Automatic for a project with my daughter. After removing the fuel rail and the coil pack on the driver side I noticed two spark plug holes had oil in it almost to the top of the plug. I'm guessing it is a bad rocker cover gasket that is allowing oil to leak into the plugwells? Nothing I could find on the internet relating to this.
After removing the rocker cover the silicone gasket was intact but wet with oil. I purchased a replacement Felpro gasket but now understand they might need grommets for the crazy bolts Ford uses to hold the cover on the head.
My dad was changing his plugs today (2000 passat 1.8t) and he found some oil down in the holes for the plugs on the front two cylinders (closest to the front of the car) and also on the plugs themselves, and needless to say hes a little concerned. he doesn't think there should be any there. headgasket?? He has 105k miles...
View 5 RepliesI have a 1997 F150 4.6 V8 and as we all know these trucks are notorious for the spark plug blowing out. Although when I bought it I never had an issue until we put motorcraft plugs in. After a couple weeks of having these plugs in the porcelain blew out of the plug with the threads still in the head. The spark plug screws into a threaded insert which then screws into the head. We replaced the plug and nearly a month later the porcelain blew again. Replaced it, same story a week and a half later. Before the motorcraft plugs I had autolites in it, and I never had the slightest spark plug blowout problem. Should I just put an autolite in the cylinder that's blowing them?
View 4 RepliesI had a plug blowout last Thursday on the freeway. I wasn't sure of what happened with my truck, it was a shutgun going off. I had to towed to my local Firestone.
My truck is a F-150 4.6 2003 with 206,000 miles.
The short of the story, plug #3 blowout. It trashed the coil and I needed a new plug. They used a Helicoli and I have been reading that they shouldn't have used a Helicoli. They should have used a Time-set.
What's wrong with the Helicoli's? Is this fixed going to last for awhile? They said the helicoli worked well. The truck had 7 NGKs and 1 motorcraft. It has all new motorcrafts now.
1997 f-150, 4.6, 147K miles. This morning I started the truck and the engine light was on. Felt a miss in the engine. Drove 1 mile and back then checked the wires. Found one not firing. Traced it back to the plug. When I pulled the plug boot off I noticed water in the recess, surrounding the plug. Once I blow out the water, I'll checjk the plug but I would like to know if this is a natural occurrence. I thought the boot would prevent water from filling the recess and sitting there. Or does the water just evaporate when the engine gets hot?
View 14 Repliesi just purchased an '01 expedition with the 5.4. I was told #5 spark plug blew out. Upon examination, it appears to be #6, second from the front driver side. Anyway, as I was looking, it just didn't look right. There was a spark plug socket stuck in the well, with the plug still in place. How to get the socket out? I can get an extension on it and it will turn, but it's tight. But I can't pull the socket out.
View 9 RepliesOkay so I was getting the misfire in cylinder 3 so I pulled the plug out and it had coolant in it. Does that mean it needs a new intake manifold gasket? That is what the guy told me at the parts store. Also can I drive it like this or will it damage the engine?
View 1 RepliesI have an 01 f150 with 5.4 triton. This has been great truck, never really had to do anything to it. It has 195k on it. Week or so ago it started running rough. So I replace the plugs and coils. I noticed some of the plug wells had oil in them. Got done and the truck is running like new.
Not sure where the oil is coming from. Not the piston as the plug was dry on the tip and truck not smoking any. I has began using a quart or so between oil changes. I have always changed it every 3k. Is it just time for new motor. Like I said it is running like new.
I found a leak today on my 2001 Ford F150 Super Crew, 5.4 engine. In the picture, it was leaking to the right of the spark plug, behind the hose. It was bubbling up from the metal. It hasn't been overheating except when I got home and idled with the AC on. What I'm facing?
View 12 RepliesMy son has a 2001 F150 with a 4.6L V8 that's blown a sparkplug from # 3 cylinder. The plug looks as if struck by lightning and has a burn groove as deep as a kitchen match stem the full length of the threads.
How difficult is an engine swap/change using another 4.6L? Neither of us have extensive mechanical backgrounds but plenty of aptitude.
Last weekend my number 4 spark plug blew out while on the highway. The truck stayed on long enough for me to get off the highway and pull over before it died. I towed the truck home. Last night I repaired it with a helicoil and replace the spark plug and coil. Now the truck cranks but won't start. I noticed that my theft light flashes fast and doesn't stop after a few seconds or during cranking. I still haven't tested relays or fuses because it was late after the repair. I will be checking those tonight.
I will be reading and taking suggestions and posting my results tonight while I'm working on the truck. I will be checking the fuel pump and PCM relay tonight. I will also try 2 different keys and checking the Inertia switch on the fuel pump to see if that tripped. The truck is a 2001 F-150 Lariat Supercrew with 150k miles on it. 5.4 liter engine.
With the many discussions on F150 spark plug blow outs, is there any consistency in which Cylinders usually go or is it completely random. In my 2003 F150, 4.6, 2wd, I've replaced #3 cylinder with insert and now #2. Currently I'm at 154,000 miles but want to travel cross country with a load. I don't want to stall out on the hwy, would it be wise to go and insert the remaining cylinders - not cheap. My mechanic is willing to inspect with a bore scope the threads and re-torque. Is there a point at which if it hasn't been a problem it won't be. Truck is used primarily for commuting and to pull a single jet ski in the summer. Both blow-outs happened at a stop-light about 20,000 miles apart with no load.
Follow-up. Did inspection, found cylinder #7 nearly stripped out - it was actually pushing up the coil. Funny thing is, this plug had already the small insert which was coming out with the plug. I bought the vehicle new. Was this a factory repair? or did my previous mechanic strip-it when replacing all my plugs at 95,000 miles? Lucking the large inserts my current mechanic uses was able to find some metal and make a good repair. Looking at the cylinder order, I have now replaced 3 of the inter four cylinders (2,3,7) should have I done #6 too, this is probably the next high risk cylinder or not?
My Truck : 1999 Ford F-150 Extended Cab 4x4 5.4L V8
So the other day I was driving the truck and it just dies on me. Tried starting but it just cranked and cranked. Got it pulled over to a parking lot and then tried to start and I got it to run again. Died a couple mins later uo the road and it will not start at all anymore. I got it towed to my driveway and I've started diagnosing some things.
I dropped the tank thinking it was a pump I replaced awhile back. The pump wasn't running but jumped to conclusions and took it back to the auto parts store. They bench tested and it works fine. I checked for voltage at the pump connector. NOTHING. So I'm not getting power to Fuel pump. Then I checked the fuse and relay for the fuel pump. Everything was okay.
I did some research and decided to check for spark. NO SPARK. Another thing I noticed the other day was that the odometer is displaying all dashes. So I'm really unsure on what to really troubleshoot. I am going back to the truck tomorrow to check a few other things. I'm not sure if the Theft light is blinking or not so I will check that tomorrow and get back to you.
What to check? Any other relays or fuses besides the fuel pump? What about any modules to check like PCM, GEM, etc. Or I've heard the crankshaft sensor could be an issue.
My truck broke down on the freeway last night. I heard a cracking noise (metal breaking) and it sounded like a backfire. The engine was running fine, good RPM's. I rev it up and the noise got worse, It sounds like a bad lawn mower or go cart. I was also smelling raw fuel.
Could I have broken a exhaust flange or the manifold? It sounds like the exhaust is bad and not burning the fuel.
There were no codes or a check engine light. I only went 1/2 mile after it broke down. I had to tow it to a local shop.
It's a 2003 4.6 with 205,000 miles.
I've got a 2000 f150 4x4 extended cab, and the rocker panels under the doors are getting rust holes in them. I would like to get mine fixed/replaced this spring. My truck is in great shape other than the rust holes under the doors.
View 14 RepliesThe spark plug in chamber 2 blew off while the vehicle was in motion (approx 35 mph). Purchased replacement plugs and when I went to install, there was nothing for the plug to grab (i.e. appears that all of the threads on the block/casing are gone . Not sure what my options are.
View 2 RepliesI took a long trip this last weekend and before the return trip I checked the oil and realized I need some. I put two quarts which brought the level just about even with the top mark on the dipstick. the return trip was fine. Next morning I started the car and right away notice that the engine was misfiring. I checked the spark plugs and noticed that one of them was loose and had some oil in it. I checked the oil and now it showed the level to be well above the top mark on the dipstick. Could too much oil cause the spark plug to get dirty, get loose and misfire? This car is a 1997 and has 206,000 miles. This is the first time this has happened. Could the same thing happend with a 1999 Honda Civic?

Driving down the highway today, I notice my truck was jerking forward a little, hard to notice almost felt like I was hitting very small pot holes. I revved up a little to see if I could notice any noises and I got a loud pop. after the pop, got a noise like an exhaust leak so I pulled off to the side of the highway and popped the hood (engine still running). Noticed the noise coming from the passenger side most forward spark plug. Then noticed the part that the coil attaches too had broke off from its bracket and was unseated, shut off the engine and pulled it out to find the coil cover had melted to the coil.
The spark plug inside was moving freely so I took it out thinking it stripped from the header. Come to find that the plug had actually separated from its threading completely so just the core part of the plug had shot out from the cylinder, the threading and socket attachment portion still fully attached. I installed a new spark plug and new coil harness and coil. Seems to be running as good as new now. Is there more to this than a simple blown plug that I need to worry about?
