I've seen some discussion about the 4.6 motor not blowing plugs, so I just wanted to add to the confirmation that they do. 106k miles on the motor, #5 came out today on the freeway.
I was looking to repair myself, but the Timesert kit is expensive.. I'm thinking I now want all 8 done so I don't have to deal with this again.
I recently became the owner of a 2000 Ford Excursion V10 (limited) with lots of extras (5.5 inch lift, dual exhaust, 37 inch tires, a 2005 front end, etc).
The intent is to use the excursion as my winter driver, towing vehicle and people hauler (things my 2010 mustang is terrible at). Unfortunately, my 5th time ever driving it, I was pulling out of my driveway and accelerating when the engine blew a spark plug. Since I do not have the tools to install a helicoil, I have taken it to the local shop to get repaired.
I am now concerned about the remaining plugs, and the general reliability of the motor. It has ~200,000 miles on it, and multiple previous owners. I have no way of knowing what work was done on it in the past. I did check all of the fluids when I first got it to ensure they where still good, but are there any other common issues with these V10's that I should check? Can I do anything to prevent any further spark plug blow outs in the future?
Here are the details. Just replaced my HPOP, IPR and ICP and while driving at 75mph I hear a loud pop under the hood. Several seconds later CEL comes on and I have no power and the engine is shutting down as normal. I pull over, get out and there is a massive amount of engine oil everywhere, I get it and the first thing I look for is the HPOP area and the "non-serviceable" plug is GONE.
I was able to find the metal piece that goes in between the plug and the ball, but no ball. I find the dimensions of the tiny ball (.25") and replace it. I order the long thread fix from RIFFRAFF install it and now I have a no start issue. While waiting for parts I change the oil and filter, clean the oil soaked engine and pray that nothing else was messed up. I do not have an AE or OBD-II, the truck has 300k on it....
My F150 with 175,000 miles on gave me a the ol' P0305 code indicating misfiring in cylinder #5. I changed the plugs and wires using Motorcraft wires and Motorcraft AGS34FM plugs.
Now the truck idles fine, does not give a OBD code but runs rough at 2,000-2,500 rpm. Tried it out on the highway and it started "bucking" a bit. Not sure what to try next.
I'm 2 hours from home #10 spark plug blew out I pulled the injector cable and coil cable is it safe to drive home that way?

View 2 RepliesI have a 22R sitting in my celica and my problem is that when I was driving home from school I stopped at a stop sign..... Well I started to take off from the stop sign and as I did Spark plug three blew out of the cylinder... (WTF) well anyways I started it back up and drove it 2 blocks to where I live and it backfired and now I have no spark to any of my wires or spark plugs I checked the Main Engine Relay works just fine, For fuel problems anyways.. other than that I believe my timing skipped during that bad backfire so Woohoo for that but any other problems that could have caused "no spark" like my igniter blew out or my coil.. I would like to know where the fuse is (if any) for the igniter.
View 2 RepliesI have a 97 F150 XL. The lighter plugs stay on even with the key removed. I just bought this truck and this seems to be odd behavior to me, yet I can find no modified wiring.
View 4 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.
I went to unscrew the radiator drain plug but the head broke right off leaving the rest of it inside.
I drilled out a little bit of it so I could drain the coolant and bough a replacement plug but there are still pieces stuck inside and I cant get them out.
Should I just drill out the remaining pieces or is there a better way to get them out?
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 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 RepliesI 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 2001 F150 4.6 threw the #3 plug on the passenger side while going down the road at 65 mph. It threaded back in and tightened up to make it the last 7 miles home. I have read that Time serts are the best option but I need this truck daily at work. Has anyone tried using the Heli Coil system as a temporary fix? I am going to order the Time Set kit but since I need the truck now, I was wondering if it were possible to pick up a Heli Coil and insert it until my Time Sert kit arrives?
View 5 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.
This 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.
