Ford F-150 - 1997-2003 :: Truck Running Rough / Intake Manifold Gasket Blown
Mar 31, 2014
I have been having some issues with my 97 ford f150 4.6 liter, started out running rough, then hydrolocked with no serious damage, blown intake manifold gasket, fixed that, alternator over charging do to bad voltage regulator, fixed that. and airbag code 52, still working on that, as well as failure to connect when trying to do diagnostic scan. now I am wondering if the engine diagnostic is still even working. still running good just a very slight vibration when warms up. I am not getting any code. or my check engine light is not showing any codes. What I want to do is force a code. What would be the safest way to force a code or force engine light to give a code?

just got finished putting her back together from a blown intake manifold gasket and run for a few miles to get rid of any cob webs and then my battery light comes on. just replaced the battery last week. and I tested the alternator and it charging at 14.5 volts bat reads when disconnected 12.9 volts so I am not sure why my battery light will come on.

I've got a 1997 F150 with the 4.2L V6. Before I got it last summer I did some research, but apparently missed the issue with the intake manifold gasket leaks on these early engines. It seems to be a very slow leak, but obviously I want to get it fixed. I called Ford to see if it had had the recall work done on it, but all they could tell me is that there wasn't an open recall on my truck (with the exception of the recent fuel tank strap recall). Their system apparently only goes back 10 years, so they couldn't even see the freakin' recall. So, I've got a few questions:
1) I know I didn't post much info, but does this seem like an intake manifold leak?
2) Are there any special tools needed to change out the gasket myself?
3) Can you all recommend any replacement gaskets? I found a few different manufacturers of gaskets, but I'm sure some are better than others.
4) Can this issue cause the computer to throw the loose gas cap code (P0455 if I recall correctly).
5) Would it be worth it to just get a new truck? I really wanted a diesel in the first place, but I also hate to give up on a nice truck with only 115,000 miles.

My 97 f150 5.4 started missing on 5,6 it had antifreeze on top of the spark plugs but i cant figure out where its coming from my truck has been loosing coolant and it seems like the system is holding pressure because every time i take the cap off the radiator overfill i can hear it hissing then i see the antifreeze level plummet there's no visible leaks that i have seen when the truck is running an missing it steams out the exhaust but when its no missing it doesn't seem to be there's no milky oil or anything the thermostat doesn't seem to be leaking either the truck has over heated a couple times due to the antifreeze disappearing or the temp wont move at all then it shoots all the way to hot and cools down within seconds to normal i just put a new thermostat in. Also it sometimes misses on 4 and my exhaust smells like straight gas i put 4 gallons in it got 29 miles out of it .

I have a fudged-up looking oil leak that my oil change guy says is probably a blown intake manifold gasket. Is this the same as a head gasket? I thought a head gasket was around the pistons. I see there is a product on the market that you can put into your radiator that plugs up leaks in the head gasket (Steel something). Is this an OK fix? It would cost $90 for a bottle of the stuff. And what is a reasonable, or low, rate to replace this gasket? And, how long can I drive the car with this condition? It has lost a quart of oil in the past month, driving about 600 miles.

Ok I got this truck from my mother-in-law for free with a blown head gasket cylinder 6 driver side. I did the replacement had the heads machined put it all back together by the book. Now I can't get it to fire on all 6 cylinders only 5 I think. Thought maybe bad gas (it sat since late November) put 5 gallons (over double the gas) fresh gas and half a bottle of b-12 chem tool. Dubble checked all plugs wires connections (coils plugs wires all new). I drove for about 10 miles oil pressure and temperature stayed perfect but no change in running truck shakes a lot and no real power. Don't sputter or backfire no engine codes other than imcr bank 2 open. Engine is 4.2l v-6 170k miles.

I took my Monte in for the annual Missouri Safety Inspection. Note: I had no known problems with my 2003 Monte SS 117K Miles. After the inspection, which passed, I was informed of a variety of problems: Intake Manifold Gasket Replacement, Valve Cover Gasket w/Intake replacement, Thermostat w/Intake Removal, Fuel Injector O-Rings w/Intake Removal.
My question is should I have all of this done? It's not cheap..roughly 1000 bucks. I know very little about this and I don't want to just tell my mechanic to do it without some research. Are these common problems with Monte's of this age/mileage and just part of the cost of owning this car. I am the original owner and have avoiding costly repairs/maintenance..it's been a great car.

Replaced head gaskets on 2003 f-150 5.4. Now I can hear a ticking noise in middle of intake by #5 port. Maybe timing is off 1 link?

I have a 1998 F150 4.6 2wd regular cab with 255,000 miles on it. Lately it has had some problems. The first is that it will run really rough when under a load, meaning when I step on the gas. It runs smooth at idle and at cruise but when I step on the accelerator it bogs way down and almost shuts off. I have changed the spark plugs, spark plug wires, coil packs and fuel filter. Now I'm thinking maybe fuel pump?
The other issue is that when the truck is having to work a little harder (i.e. pulling a trailer or running in the summer with the AC on) it will start to run hot. I have changed the thermostat, flushed the coolant, cleaned out the radiator, etc. and it still does it. Could both of my issues be related to a fuel problem??

I am about to replace the intake manifold and gaskets. I know all of that process, but first question is if there is anything i should do whilst in there. Second question; what can I do with my intake to get more power? Mainly just kind of wondering before I get my parts ordered.

last year it did this n i put a nother hose clamp on that rear tube and just happened to stop . n now back but the ting is that its not wet at all at the hose but at top of head bottom intake hmm . this is all just during the initial start of truck stops even before truck really gets warm

I have a 2001 F150 4.6L auto. This truck suddenly started running rough. Cleared all codes and re-scanned after starting truck. The codes are as follows; P0135, P0155, P0443, P0740, P0743, P0758, P1451, P1460, P1747, and P1760.
My question is; is it normal to have this many DTCs come up at once? Could my PCM be faulty causing this problem? Can you swap a pcm from the same year truck with the same options without reprogramming?

I just bought a used 5.4 for my 99' F150 4X4. My current engine has a blown head gasket. Anyway, I was able to hear the engine run before I bought it, and was able to check it out some. (oil, anti-freeze) I was told that this engine was bought from a salvage yard with 50K, and 50K more put on it before I bought it.
I was also told that the intake manifold is newer, from Autozone, and it has newer Accell coils. My question for you all, is ..... What do YOU think I should do otherwise before I install this engine. Oil pump? water pump? seals? ...

I was replacing my spark plugs and one screw holding the ignition coil stripped while another snapped. I have change 3 plugs (the easy one) and could have more problems. I spent half a day trying to drill the screws out to no avail and also noticed the intake manifold is plastic. I was thinking of swapping it out. This would alleviate the broken screw problem and make pulling the plugs easier. It also looks like it's just 8 bolts. Would swapping a new intake manifold in add any performance gains? Is there a manifold others recommend?

2001 F150 4.6. Just replaced all 4 oxygen sensors and spark plugs. Replaced rubber grommet on brake booster as it was leaking vacuum.
Truck is still running rough hesitating.
Pulled codes came up as PO141 oxygen sensor heater circuit. PO171 passenger side cylinders running lean. Fuel trim outside limits.

I have my 4.6L engine on a stand in the garage. I think I have a blown head gasket. I am ready to remove the heads.
My Haynes book says: "Caution:Use the required camshaft retaining fixtures to lock the camshafts and leave the tools in place."
A google search shows nothing. Why, what does it do?

I just purchased a 2003 F150 Supercrew 4.6 that had been wrecked, but somewhat repaired. I knew the owner said it had a blown head gasket. It has water in the oil (small amount asi it is lightly milky) and water starts dripping from the exhaust after it has run for a few minutes. I did not run it long, but throttled it up to warm the engine. It started dripping soot filled water from the exhaust connections. I bought it to put a 4bt in it anyway, but want to sell the motor with the ability to tell the buyer the skinny on it. I drove it on the trailer and off with no apparent loss of power noticeable.

If the exhaust manifold gasket is broke / cracked will it making a ticking sound?

I have a 98 f150 4.6 4x4 with 175.000 miles, I suspected the intake gasket is leaking, I'v never done this before. What is involved with this type of repair? Will the intake gasket leak bad enough to leak antifreeze on the floor? Is it okay to continue to drive with this problem? Bad weather is on the way.

I have a 03 5.4 F150 SCrew... The intake was leaking on the passenger side (water outlet tube meets plastic).
Putting in the Dorman replacement and noticed that the front cylinder drivers side (#5) had a decent amount of coolant in it.. None of the others did. I've drained the coolant already and was wondering should I just put this back together and see?
The water outlet crossing has a hole right next to this cylinder and I can't see any cracks and not sure if the gaskets were leaking under it.
Seems like if the head gasket was blown I would see it in more cylinders? It never smoked or run bad before I got this leak... Drove it maybe 10 miles with it leaking out onto Cyl#1. Ran fine, never missed.
I just don't want to put this back together if the head gasket is blown but I don't know what to do.

I have a 97 f350 crew cab xl stock everything. 351 windsor in it I do believe. as of right now He is broken down pulled apart in my garage. Due to a much requested headgasket replacement. In any event long story short I got him all apart to discover that there was someone in it before me & had broken the infamous exhaust manifold bolts (5) and two of the lower intake bolts, (of course I've tried the correct route in removing these broken bolts/studs but again the year of the truck (1997) & its bone stock no way their moving...
So of course I tried the next best thing (on a budget) which is to drill them out, but I went to far into the exhaust manifold bolt holes, And now I believe that I've ruined the heads is this so? If so who knows where i can get a decent set of bolt on heads ready to go. yes this is my daily driver & since He's been down I've been going deeper in dept.
