Ford F-150 - 1997-2003 :: 1998 - Engine Ticking Noise Very Noticeable At Startup
Jun 20, 2012
I have a 98 F150 Supercab 4x4 with 4.6 and an auto trans. I have 107,000 miles on the truck. Recently developed a engine "tick". Upon start up the "tick" is very noticeable. Seems to go away after its been driven a few miles and everything comes up to operating temp. I have checked the exhaust manifolds, all studs and nuts are still there. There are no noticeable holes that I could feel in the manifolds. Read some other posts here that have the "tick under load". Mine goes away once everything warms up. What to look at or for?

I've got a 2003 f150 with the 5.4 and 128,000 miles with an engine tick. Its not an exhaust leak I know that for sure. It has came up in the last 20,000 miles. I've used motorcraft 5 20 w/ motorcraft filter. I've tried a kreen engine treatment with no change. Heres the description/syptoms:
-Slight clatter for 2-3 seconds upon cold startup (happens very rarely)
-top end ticking that is loudest and most noticable when warm (quieter when motors cold)
-not timing chains/tensioners etc because the noise is coming from the top end and most noticeable on the passenger side.
-at idle the tick is present-when you rev at idle, the noise goes away.
-Driving (or having the engine under any load for that matter) the noise gets louder.
-Anytime I accelerate, tow/haul, go up an incline the noise gets worse
-Sounds like a "whirring" sound from within the dash.
With all that said I am thinking the lash adjusters are getting noisy. I had a certified gm tech that has 40 yrs mechanic experience under his belt and builds prostreet muscle cars on the side look at it. He listened to it to it and that was his diagnosis as well as its not that bad so just live with it. The noise at idle doesn't bother me, its when im driving with the windows down. The noise drives me crazy and is a little annoying to me.
Heres a link to a video of the sound and keep in mind it is much louder now : Triton engine noise/tick - YouTube

So on a cold start I keep hearing this ticking noise. Not every time, but more often than not.
I have two thoughts:
1) Low oil pressure causing timing chain tensioners to allow slack in the timing chain. Oil pressure builds up after about 1 minute of driving.
2) Oil Restricter in the valve cover starving one side of the valve cover?

I have a 2001 5.4 V8 with 55K miles and the tow package. On acceleration the engine makes a ticking noise. Engine seems to run fine, no misfire.

My F150 at startup is reving real high, almost max rpm's, like the pedal is on the floor. What could be going on?

About a week ago my 1997 F150 4.6L 2WD starting a ticking noise. I had used high mileage full synthetic Mobil 1 and a Motorcraft oil filter for the previous oil change and yesterday had another oil change using regular Mobil 1 synthetic and a Motorcraft oil filter. Had never used high mileage oil before.
Since the high mileage oil is supposed to have extra cleaning agents in it to remove the sludge buildup in the engine, could the sludge have found its way into the oil pan and possibly clogged up the oil pickup tube? The ticking was not continuous and would be at idle or acceleration.
No rhyme or reason to when you would hear it. I also wonder about an exhaust manifold leak which could sound like ticking. If the problem is an oil pickup tube being clogged up, can the oil pan be removed with the engine still in the truck?

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?

97 f250 4.6l engine pegs the temp gauge after start-up. the oil pressure light comes on then after a few miles down the road anti-freeze blows out the pressure cap (15LB) then the temp goes down ,the oil light goes off and everything is normal. no its not the thermostat, i changed that and it still does it. whats up with that?

We have a 2002 F-150 4.6L 4x4. The engine went bad and we bought a new engine (remanned ATK). Had this engine installed and a year later it was bad and was determined it was a manufacturer defect so they sent a replacement engine under warranty.
We had this new engine installed. The mechanic fired it up and it backfired through the intake. They claim that the compression is good, the fuel pressure is good, and the timing is correct. Can they check these things when the truck is not running? The mechanic is completely frustrated with the situation...
Everything I read leads to a timing issue but they say they checked it so before I go in there screaming I want to make sure it couldn't possibly be anything else...

My wife is talking to someone about purchasing a 1998 4.6 4x4 EB Expedition. The owner says the only issue is a tick coming from the driver's side head. He claims the shop told him it was "just a cam stator". Now, say what you will, but I've dabbled just enough with mod motors (2v and 3v, 4.6's and 5.4's) to feel like I'd rather stick to old pushrods. I've never heard of a "cam stator" on a 2v 4.6. I also realize that stator is a word that gets tossed around a bit by people who don't fully understand what it is.
Now, this is a relatively high mileage engine (something like 220k I think) so I know it could be a whole slew of things from cracked/leaking exhaust mani, lifters, timing chain, etc. But, in all my searching, "2v 4.6 cam stator" keeps leading me to people troubleshooting pushrod distributors, 3v VVT troubleshooting, and alternator related posts. Is this such a thing, what this shop may have been trying to refer to? He claims it's done it for about 5 years now, and runs perfectly fine. I'm leaning towards lifter, but the truck is 3 hours away so I haven't got to check it out yet....

Just got new tires Friday. Now I have a very noticeable shaking right at 35-40mph. Doesn't do this at any other speeds and test d up to 80mph. Took back to where I got the tires and told them and they rebalanced them and yet it still does it. Could it be a bad tire? What am I missing?

Have a 1997 2wd F-150 XLT auto trans with 305,000 miles that has developed at vibration that is most noticeable at 55-60mph. It seems to start at about 35, but at 55 you can feel it in your seat. When it's vibrating shifting into neutral doesn't change anything.
Drive shaft u-joints: two rear replaced not too long ago (5+ years?), front joint by transmission seems to move freely, but isn't excessively sloppy, carrier bearing okay. Have done the following with no improvement:
Re-balanced all tires, no problems noticed during the balance;
Replaced first right and then left rotor and wheel bearings, no change.
Several mechanics have driven it and made different pronouncements, it's not: transmission, rear-end, tires, u-joints or carrier bearing. One mechanic ran it while up on his lift and didn't see a driveshaft balance problem. Last suggestion was that the left wheel bearing were "on their way out", so they were the most recent change. It's drivable, but not fun and it produces a lot of noise in the cab.

2003 F150 5.4L Tow Package 140k miles... Had coils, all plugs/wires replaced two years ago due to vibe climbing hills. Now at startup in the morning for a minute or two during idle, the engine vibrates severely then subsides and runs fine rest of day. Doesn't do this every morning. Truck lives in FL. The issue is either temperature related or moisture related. Ford service has the truck presently and attempting to diagnose from an overnight stay. They already 'fixed' the problem last week by replacing #1 plug/wire and resetting the power control module (pcm) but two days later the problem came back. Tech said today that the plugs currently installed are Bosch (any issue with these plugs?)

My 98 F150 4WD with 83k on it has a significant pull to the right most noticeable on the highway. I have to keep the wheel turned to the left to be able to go straight. It use to be intermittent but now is constant. Had a frt end alignment done twice with no change. Recently after a long drive on the highway on a crazy hot day, I pulled into a rest area & noticed the L/F wheel was very hot to the point where I thought the plastic center cap might start melting.
The R/F wheel was only warm. This makes no sense to me because with something causing the L/F wheel to heat up I would think it would pull to the left. This has bothered me so much that I've driven with 10psi less in the L/F wheel hoping it wouldn't pull to the right so much but it had no effect. I did recently have the left upper control arm replaced because it was clunking. It was doing this pulling prior to that & it continues.

My aunt has a 1998 F150 with the 4.6 V8. with only 40,000 miles.
Two years ago when she tried to leave work the truck would not start, it would crank over, but it would not start. She had the truck towed home and we figured out it was her fuel pump went bad. She did not have the money at the time to fix it, so she let it set and drover her nissan around.
I know after sitting for a few years the piston rings will stake (rust) to the cylinder walls. Usually take the plugs out, and pour in some oil, PB blaster,etc....and let it sit for a day or so, then turn the motor by hand to free it up.
Well She decided to get it fixed finally, and had it towed to the local ford dealer after sitting in her driveway for two years. Ford calls her later in the day and tells her the battery is dead and wont hold a charge, and the engine is siezed/locked up. They tell her it needs a brand new engine and could cost $5000. + after all is said and done.
She calls me asking what she should do. I told her BS! it only has 40,000 miles, and it does not need a new engine. It just needs to be broke free from sitting. I told her to have it towed to my house and I will fix it.
So today she had the tow truck bring it out to me. Tow truck driver tells me that ford said it has a bad fuel pump ( we knew) and that the motor has a spun main bearing in the motor..and asks me if I was going to rebuild the engine.
I tell him the story on the truck and he shook his head..and said yea..Ford is Full of it! I call my aunt and tell her what the tow truck driver told me, so she calls Ford..and asks what they did to the truck? Ford said, the truck has a dead battery, bad fuel pump and a spun bearing. She asked them how do they know it was a bearing?
Ford said they got the truck to run but the engine made a horrible noise like a bad /spun bearing inside.
I asked her, how did they get the truck to run with no gas/no fuel pressure if the fuel pump is out? The only way they could is with spraying Starting fluid ( ETHER) into the motor and fuel injection motors HATE that..they will run like total crap...
Bang, etc. because none of the sensors are working correctly..and makes the computer go OH CRAP. It's the end of the world!
If they (ford service) broke the motor free..I wonder how bad they did it. Did they FORCE it and break something internal ( bent a rod, wrist pin..)? I can't prove it, if they did.
So the truck is at my house and I am going to check it out. I am still going to pull the plugs and put oil inside, turn the motor by hand to make sure it is not locked up or messed up internally from them "working" on it.
I have never heard of a bearing going bad by just sitting. I have never worked on a 4.6 mod motor..and I know nothing about how good or bad they are... but I am soon to find out!

I have a 1998 f150 4x4 with a 4.6 triton vin #w and only 150,000 miles but its smoking. On first start up everything is good to go but when the engine reaches operating temperatures it will smoke.
It does not smoke all the time, just on takeoff. Such as after taking off after sitting at a red light it will puff a cloud of smoke from both sides of the engine. The engine is smoking blue so I know its oil its burning.
I pulled the valve covers off last week and the engine is clean, no sludge or gum. Power is good, runs good, and has good compression. Why its smoking.

I have a 98 F150, 4.6L with approx. 245,000 miles on it. recently it started, then studdered a little bit and died. I managed to get it re-started, it then shuddered a little more although I was able to drive it back up the drive way and park it. Now, it will crank however it does not even attempt to fire. The sound that it makes when trying to start seems odd to me. Like the engine is just turning against a constant resistance instead of the normal starting sound. I tried shooting a little starter fluid into the throttle body and nothing changed. I pressed on the shrader valve and got a spew of fuel to come out so it seems that it might not be a fuel problem though it sure sounds like one. Just curious, what are the symptoms of a truck with no compression?

I have a 98 f-150 4.6L 5spd that has a weird rattling noise coming from what sounds like the engine. The noise will only happen when the truck is in gear and under a load. It will not happen if I keep the RPM's low, unless I am going up a hill. When I rev the truck in neutral, the rattling noise isn't there. Also when I'm driving and hear the ratling noise it will go away when i push the clutch in(which im guessing takes the load off) but will come back when i let out on the clutch. Seems to happen most when I'm in gear and trying to accelerate.

When I turn left a "clicking" noise appears, it's rhythmic and I figured it was the CV joint at the drivers side going bad. Bought a new one and installed it. Clicking seemed to get away for maybe 5-7 days. Then it occurred again. Because the package in which the cv joint arrived was very roughed up I thought maybe it took damage during delivery and bought a new one. Installed and guess what? Took a drive after that, NOTHING and now it's clicking again. It's so loud you can hear it when you drive behind my truck and I'm turning. Doesn't seem to make a difference if I brake or not.

I have a 1998 F150 with a 4.6 engine and is a 4x4 now the other day when I was backing out of the garage I heard a clunk noise and it seems like it is coming from the right front, so I tried it going forward it made the same noise but not as bad. There is no road noise and all the u joints are good and tight, the noise was when I gave it a little gas. My question is the front cv u joint would this make the noise? And what about the hub? What is the proper why to check the CV joint and the hub? The noise was when I was in 2 wheel drive.

I recently sold me 91 F-250 and got into a 98 F-150. It's a SuperCab 6.5' bed, 4x4 off-road, 3.55 gears, 5.4 v8 auto. I love the truck, but I am having an issue with a noise at startup.
Every time I start the truck it fires right up but it makes a grinding noise AFTER it starts for about 3-5 seconds. I thought the starter wasn't disengaging in time so I replaced it. The starter I took off was fairly new. It's teeth had just a little wear and the flywheel had no visible wear. I put in the new starter and there was no change at all.
I also changed the oil and filter using Motorcraft 5w-30 oil and a Motorcraft filter. I also started it without the serpentine belt to rule out a pulley bearing. What the noise could be? The truck runs absolutely excellent, by the way.
