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 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.
My 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.
I 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 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 RepliesLast 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?
I used to have a 1999 Mercury Mountaineer 5.0. Loved the truck but sold it because I didn't have a place to store it.
So I bought a 2000 E.B. Explorer! I love it thus far, I was doing a tune-up and now I hate it. I was changing the spark plugs and one of the spark plugs had a lot of rust around it. As I was chipping the rust away so I could get a socket around it coolant started to come out right below the spark plug
I have attached pictures too.
I don't know what this could be. I have done my research, anything from the lower intake manifold gasket to a cracked head. Need info about this type of leak? its no where near any gaskets, I have a friend that says I could have hit a coolant chamber but I wasn't banging hard at all.
I've noticed a spring of coolant shooting out of a connector that I'm assuming is connected to the bottom radiator hose via a smaller hose. Is there a hose that splits off the bottom radiator hose that is smaller. The leak is not coming from the hose, but the connector it's hooked to. Is this a replaceable part? What is it for?

The 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 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 Replies01 F-150 7700 ed. I have a 4R100 Tranny with a 139K miles. It has been rebuilt. Ever since the rebuild (over 10 yrs ago), if I park the truck for a week or so or more, I will end up with a decent size puddle of trans fluid underneath the truck. I took it back to the shop that did the rebuild a couple times, but they could never find anything. It leaks enough to where my fluid level drops enough to cause the transmission to slip in a U-turn because the pickup tube becomes uncovered. I have a couple theories, but am wanting to hear from the collective.
Theory #1 When I park it on my slightly sloped driveway I don't regularly use the parking brake, so it rests on the gears, which eventually forces fluid out an overflow or breather tube.
Theory #2 (a very thin one) due to pressure changes associated with the weather, fluid is somehow siphoned out a breather tube due to some blockage internally in the tranny to where it's not equalizing with the outside air and has a high pressure within...
So my 2000 F250 has 182k and I am not sure when plugs were changed. Its got the 5.4. My 2001 Excursion has 102k on the v10 and I've read a few threads about blowing plugs and now I am scared out of my mind. Do I need to worry about breaking them or stripping anything?
View 6 RepliesI have an 01 supercab. 5.4 Triton 135k. I have begun to smell coolant the last couple of days. Have seen nothing leaking and truck doesn't run hot.
Will investigate more this weekend. Where to start looking for this. It has to be leaking somewhere. Windows don't fog and the smell is there all the time. I live in florida so don't use much heat.
Not the heater core. Heat works fine and no smell from the vents.
I 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?
View 10 RepliesI have a Toyota 2001 Echo and after about 5 min of driving, it starts to stutter when I step on the gas and shake back/forth. It gets worse going up hills. Once it starts, it continues at any speed and doesn't have the normal power but doesn't die. Stepping on the gas harder doesn't increase the RPMs like it should. Thinking it might be the spark plugs, I removed the cap on one plug and found the well with about 2 cm of clear, yellow oil. Is this bad? if so, how bad?
