F150 Engine Problems

[huntnphool]

If you had any oil on the dip stick you need not worry about oil loss, my bet is along Jackelopes line, check the coils, sounds more like you have a bad cylinder.

If it's got oil and coolant in it, drive it to your local O'Reilly's or other parts store with a scanner and see if you have any fault codes.

70k miles is typically the timeframe that I would lose a plug or coil.  I try to change them on that interval no pro-actively.  To me that is what it sounds like.

i had a 97 f150 that I drove 195k miles and lost a few plugs and coils along the way

I have an 01 f150 that i have 110k on now and changed them all at 70k and will again at 130k -140k mode.

When I lost them, it typically ran really rough and went into limp mode as soon as the light came on

I was planning on stopping at one on the way home from work tonight and borrowing one for a little bit. If they wont let me ill just get more coolant to add to the system.

Im now concerned that i might have too much oil since i added about 2 quarts while it was warm.

Ill look more into it tonight after work.

Best $20 I ever spent when it comes to diagnostics!

have one, they use oil. if you long trip or tow.. wouldn't worry too much unless it becomes an issue... lots of blanks on the oil issue, interval change, type oil, truck use ect...

the plug/coil discussion is first. change 'em would wires too... only 2 coils (one per side) not too $$...
for the sake of money, plugs first then wires, if still present go for the 2 coils.... probably burnt off electrode/ big gap from many miles....
passenger back plug sucks..... proper torque on plugs, they rattle out if you don't and can result in pulling thread$$ from head.

after this, bad fuel, filter, fuel pump would be next direction... water in EFI will result in skip/missing but not kill the motor...

any idiot lights/ has it thrown a code?

An '01 f-150 4.6 has 8 coils, no plug wires.

sorry mine was a '99/00 going off that info...
with that in mind, easter egg with 1 coil would be cheaper than 8X $$ cost... after replacing all plugs...

Knuter valve?

Catastrophic converter?

Muffler bearings?

Piston return spring broken?

Was a full moon tuesday....

Halogen fluid is low.

got it to oriellys and tested. Missfire on cylinder 3. Went to swap the coil and it just fell off. Then went to pull the plug and it was just laying there. Not threaded in at all. Now i cant get a new plug to start threading. I know a couple of you guys mentioned having blowing plugs. Is there a way to fix it without having to pull the head and retapping the hole?

[jackelope]

There's a special helicoil kit you can use to put a threaded insert into the hole. It's not really something is recommend doing if you're not experienced. It can be done and it's not cheap but it's a hell of a lot cheaper than a new head. A shop will probably charge you a couple hours labor iffffff they can do it.

Send coach a pm, he owns his own shop.

Pretty common issue . I recommend pulling all the plugs on a cold engine and replacing them and helicoil as needed . the kit isnt too bad on cost and can be done in the truck . the #4 and 8 cylinders can be tricky but done . Dont use gobs of anti sieze just a pinch . I have the kit if you want to borrow it . I see your up in Everett Jermy up at Auto and truck is a pretty good guy if that works for you . If you wanna give me a ring its (206)522-6100. Corey

My brother had this happen to him, blew the plug and threads right out of the head. The problem is FORD is pricks and knows they have a problem and wont fix it. Problem being the plugs only thread in about 2 turns and thats it. My dads I replaced all the plugs and could actually unthread the plugs by hand. It was only a matter of time before they blew out also.
