Ford F-150 - 1997-2003 :: Knock At Morning Startup
Feb 25, 2014
1997 F150 4x4 210,000 4.6L Windsor 5 Speed. Engine totally rebuilt 15k ago (besides for timing chains and tensioners). No codes thrown.
This morning when i started my truck, it made a knocking sound (almost like metal slapping) that seemed to be coming from the bottom end of the engine. At first I thought it was a spun bearing, but then the sound went away after a minute or 2. I have Google'd the problem, and have found a few diagnoses such as: oil draining back from the filter (or something like that), or an exhaust manifold leak that stops when the metal warms up and expands, or even the starter motor not being aligned right and not disengaging properly...
This is the first time this truck has ever done this. I changed the oil and filter about 1000 miles ago with 10w-30 oil and I believe a WIX filter. Also, this is the first time using the WIX filter
The weather this morning was around 51*F, so not too cold (to me).
Also, a few weeks ago when I changed my oil, I noticed milky white stuff only on the bottom of the oil cap, and in the feed neck. The rest of my oil looked like perfect used oil. After I noticed the milky stuff, about 2-3 times a week I would clean the stuff out of the neck and off of the cap. Just recently, there hasn't been as much milky fluid. My coolant level has not changed since I marked it during the oil change. A few buddies have said it might be condensation, but it's never been like this before.
I guess my question is, is this something that could put my truck out of service if left untreated? I'm assuming it's not a spun bearing because the noise goes away, but is there a possibility coolant could be leaking into the case but stay the same level in the reservoir?

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?)

I've got a 1997 Honda CRV. Recently when you start it up in the morning there is a terrible clatter coming from the engine. Yet, once the car warms up, the clatter totally subsides and the car runs and drives normally. Turn the car off and then start it again, the clatter comes back - but then in a minute or so the clatter is gone and all is well. I've checked the fan area and belts - nothing is caught in there. Seems like the sound is coming more from the engine. Can't figure it out. By the way - did I mention that the car now has 338,000 miles on the odometer? Other than that, the car runs fine. Is it time to give up the ghost?

So my truck a stock 2000 7.3 started smoking when I would start it up in the morning... figured it was a glow plug issue. Checked the relay it was good, checked the glow plugs found 2 were bad replaced them.
Thought I was done, well I started it up and took it for a drive. still smoked... thought no big deal I know some oil leaked into the cylinders doing the glow plugs.
Then it started rattling like a lift went out, no more smoke though because the truck was warm... shut it off at my buddies. Limped it "it actually still drives ok" 5 miles home.
From my research it sounds like an injector. I have tried a buzz test and they all sound the same.

My 1997 f150 4.2L 2 wheel drive truck has been running rough only in the morning. In the last year I have changed the plugs, wires etc. As soon as I start the truck and attempt to drive, it is very hesitant, runs rough etc., but if I only give it a little gas and not push it - the truck will run fine. This will only last about 45 seconds and then it runs normal for the rest of the day. I do not have original FORD sparkplugs and someone told me that might be why. I spoke to a mechanic (did not work for Ford) and he told me it wouldn't make a difference.

F150 2001 265,000 Super crew 5.4 Fuel Injection ... Runs great. Good gas mileage. Outstanding workhorse.
The problem only occurs on cold mornings. The engine turns over easily and fires right off. Most of the time it will idle fine without any throttle. Hower, the slightest pressure on the gas pedal that the rpm drops and the engine stalls. It starts right back up same problem.
I come back later in the day and it starts and runs fine with and without load. No codes and the the fuel pump, fuel filter, and been replaced--no change.

I have a 2000 f150 4wd 4.6. It wouldn't start this morning. A few years ago I had to change the inertia switch so my first move was to bypass that, which didn't work.
After that I gave it a shot of ether to see if it would hiccup and tell me if I had spark or not. It started up, ran rough while the air cleaner was off, then cleared up and ran fine, and is now starting/running fine again.
The problem is that I have to take the truck on a trip Saturday, and I can't figure out what the problem was if the truck is starting. What it could have been? No check engine light or anything either.

Had it before, code p1401. Changed out dpfe and it worked for 6 months. Now spark knock again. Now though I have no codes though. No vacuum leaks that I can find. New egr from before I had the problem. I applied vacuum to the green hose and it stumbled so the ports should be ok. Snytime I go above 3000 rpm i get the pinging. I replaced the dpfe again and no difference.

I have a 2000 F-150 xlt off road with a 5.4. I have owned the truck since 2001. The truck has 170K miles on it and I change the oil between 3-4K miles. The last couple oil changes I have I have noticed I haven't been draining as much out as I usually do, this past oil change was about 3 quarts low. I thought it was very odd. The truck runs great and does not smoke or leak oil.
This morning I got in and noticed a tick or slight knock, thought maybe it needed warmed up. After a minute. I shut it off and checked the oil, to my surprise there was next to no in the engine! This has me very worried now. I haven't checked my coolant since last oil change so I'm not sure if that's where it's going. Where to start looking, I'm missing like 5 quarts of oil in 3300 miles. Again the truck run great and does not smoke at all. I was getting ready to change it this weekend, always run high millage 5w-30.

So for the past few months I have been hearing a knock sound when taking off from a stop. It does it every time, and its loud enough to hear distinctly. It sounds like it is coming from underneath the cab, maybe the trans or rear engine area. I thought maybe a mount. It only does it when taking off from a stop it does not do it while driving. Where to start. I hope it isn't serious, at this point it is more annoying than anything else.

1999 F150 New 5.4 ~350 miles on it. Longtube Pacesetter Headers with cometic mls gaskets. Stainless bolts.
It is making a knocking sound and I can't tell if it is internal or from the headers. I have a video that I hope you all can tell what is. I tried listening to the block with a yardstick, but I couldn't notice a significant increase in volume but my hearing isn't the best. I made sure all the header bolts were tight, but no change in sound.

I've got a 97 truck, broke the crank, swapped in a motor from an 07. Heads down is 07, intake up is 97. had heads planed and a valve job with new seals done. Left it alone from the rings down. Got it in this weekend, running today. Ran it in the driveway with no load for about 30 minutes, top end was noisy for about 5 minutes till the top end got good and oily (I'm assuming). Purred like a kitten, sounded real smooth. Took it for a drive around the block, heard the clatter in the video below. It's almost always there when driving. Brought it back, turned it off to check oil, it was a quart low. Added oil, startup was VERY labored with a real hard knock in the bottom end. Ran like poo till I gave it some throttle for a couple seconds, then it cleaned up and idled well. Let it run for a couple minutes, turned off and let it sit for a couple minutes then started back up, same thing. Very labored with hard knocking.

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

I am experiencing a fan noise that precedes the ICE during morning startup. It sounds like a model airplane with a cheap, buzzy propeller. It is not the cabin blower and it comes from the front of the car. It goes for about 10sec and then the ICE fires up, drowning out the fan noise, which I presume fades out. And then I don't hear it again when the ICE shuts off. I also don't hear it at a stop light or subsequent restarts. Seemingly, it only does it after it has sat overnight.
It wasn't always like this. Nothing has changed in my routine. Build date Sep 09. 10000km.

I have a 97' F150, 4x4, Auto trans, 5.4L Lariat. Power locks and windows. Auto locking hubs. It doesn't appear to have any theft deterrent system installed.
It has been sitting for some time. When I hook up the battery the headlights, dash lights, and wipers turn on and the horn starts blowing continuously.
Cycling the key in the ignition or door has no effect. Cycling the key to the start position does not engage the starter.

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 am going to start from the beginning because oftens times we don't provide all of the information that may be pertinent to the correct diagnosis or repair. It'll be kind of lengthy! It all started about 3 days ago when my wife told me that my truck was "shaking." I said, "ok, just drive the car til' I can look at it" The next morning, the I was able to look at the truck. I had a cylinder 8 misfire detected. I drove it for about 1 hour that day to and from work. I did this so I could see what what the "shaking" was. It was actually what I describe as a "shudder."
Anyways, I done a fuel pressure check and all was well. I took of the coil, tested it, it was fine. So, I took out the plug to inspect it. It was wet! Not drinched, just mildly damp. I dried it off, cleaned it off with carb cleaner and it fired right up no hesitation no nothing. No CEL light, no shaking, no shuddering. It ran perfectly normal. I let it warm up to speed and took it for a test drive around about 6 city blocks. All was well. So I took it on the highway for about a 2 mile stretch. I was givin' her some juice pretty hard to see if it would misfire. Upon acceleration I heard a screech. Now this is where it get's interesting.
The screech that I hear, I just related it to the belt because it's done it ALL the time. When I first bought the truck it squalled like a whipped puppy cause of a cheap belt. The good ol' bar of soap trick fixed that! But, ever since then, it upon shifting, or under acceleration it would screech then stop. So anyways, on the highway run, it screeched while I was accelerating. It did this from about 60mph-80mph. I then, turned around and came back home. By the time I got to the stoplight to turn off towards my house my oil light was on and the engine was knocking. Not a tap, a knock.
I slowly coasted home not going over 20mph and pulling it out of drive as much as I could. I get home, and I check the oil and there is nothing on the dipstick! WTF!? I always run Mobil1 Full synthetic and put it 6qts. It doesn't smoke, doesn't leak or nothing! So I freaked out and went and bought 2 qts of Valvoline Hi-Mi and poured it in. It brought up the hash marks and quieted the deep knock. Later that night after work, I done a full oil change and flush and put back in my Mobil1 Fully synthetic 5w20. It now knocks at startup, and smooths out to a tic. Then at idle, it sounds like a light knock. It appears that it goes away upon acceleration.

I've got an '02 F150 with a 5.4L Triton. Despite being 10 yrs. old it's just passed the dealer warranty mileage about 80,000 miles. Due to a family situation it's been sitting idle for upwards of 2 or 3 weeks between startups.
When I do startup there's a puff of blue/geyish smoke, the engine idles rough for about 30 secs. and then everything smooths out and she runs normal.
I haven't noticed this issue before, I would add the temps here have been extremely cold the last few weeks. What direction do I point a mechanic in so he doesn't waste time or money on a diagnostic.

I have a 2002 Chevy S10 with 155,000 mls with the 2.2 liter. When I start it up in the morning the oil pressure goes to about 70 lbs, then after it warms up it drop to about 30 lbs. What could cause this?

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?
