Previous template Next. Hello everyone, new to the forum. Yesterday as I'm coming in from a day out the motor began making a knocking noise. Whether in idle or if I rev up the engine same noise persists.
Maintenance has always been done by Yamaha recommendations. Oil was full. I replaced the spark plugs today, and no change. Almost sounds like valves tapping but I don't think it's that. Here's a little video, any opinions are greatly appreciated!! Last edited by 21seahunt ;PM. Reason: Forgot video link. Tags: knockingyamaha That's a pretty deep noise, I would pull the gear case and run it again, this will eliminate the gear case or prove it. Comment Post Cancel.
Pull off the engine cowl and now listen. A screwdriver to the block and the handle to your ear may narrow down where its coming from. It sounds, from the video, as if it's the power-head itself and its not a loose valveway too deep a noise. In any case, don't run it more than you have to.
Also, from what I understand if it were the harmonic balancer the motor would have had a bad shake and all over the place also a loud whine, which I never noticed.
The balancer issue WON'T be in the shop manual. Its not a replace after 1, hours, etc. Its short of a re-call but Yamaha knows of the problem and was addressing it.
Their supposed to whine when failing. I've never noticed it when my boat was at the marina, it was mentioned that they mechanic could hear it. It was under warranty and was replaced. My understanding is the units shread some material which will get in the oiling system and cause blockage. That's what destroys the engine, lack of oil to bearings, etc Some F's don't have the balancer at all and its been posted here, there's very little in-balance on those engines Thanks Townsend.
Unfortunately I have a feeling that's what I'm dealing with. Some have said the motor would have been jumping around or rattling if that was the case, but it's not. And some of the videos I've seen on line don't either.
But the mechanic will pull it out of the water tomorrow -Wednesday. I'm hoping it's not too bad, but that's just hopeful thinking.The U.

Messages: Hey guys our ford f with the 5. We will probably pull the motor soon and do a master rebuild kit on it. Its gonna stay parked for about a week. TandMNov 10, Messages: 11, RestrorobNov 10, I recommend a ford crate motor which is rebuilt by the same guys who built it in the first place, not some general garage grease monkey.
Messages: 21, I thought it was a rod as well. TandMNov 11, I would send that crank out to a machine shop to be reground and install new bearings. The machine shop should be able to tell you if it was caused by dirt or lack of oil etc. Den69RS96Nov 13, TandMNov 13, Sounds like the classic symptoms of rod and main bearings but one other thing to check is the crankshaft pulley and what is referred to on a chevy as the "harmonic balancer" not sure of Ford's terminology.
My company had a service van that started making similar noise and it turnned out to be the afore mentioned. Van still running now with nearon it. Would be a really cheap fix if this happened to be the case. Just my half-fast opinion You must log in or sign up to reply here.

The only way I can describe the noise is that it sounds just like rod knock.
It was taken to multiple dealerships and looked at by a handful of mechanics and it was believed to be rod knock, but since that diagnosis, I have put on at least 30, miles with no problems except for the noise. If it isn't rod knock, what do you think it could be? What about a crack in the torque converter?
When a rod knocks, it is an un-mistakable noise you'll remember for sure I wiped a rod bearing on a chevelle racing one night My friend told me it could go a long time or blow tomorrow, but that I likely had about miles before she was done I think I got miles and it just siezed up while driving on the interstate The dash board lit up like a xmas tree Engines were a lot cheaper in them days, I think I bought a nice out of a camaro for As for what your knock might be, place a long extention against the engine and place the other end to your ear, you should have a stethascope for the engine and be able to hear the noise very clearly and by moving the extention to different places on the engine, narrow down the area it's coming from I think that s a good place to start as I've heard noises coming from a converter that sounded a lot like a rod knock Also you might want to make sure the dust shroud for the tranny isn't being hit by the torque converter Sticky Lifter - The engine uses engine oil to keep the valve pushrod linkage tight - no more adjusting lifters - the enging oil pressure does this for you.
Thicker oil will keep the lifter from compressing, but if it's not bad, it's a non-issue. My old car had one for well overmiles. It could also be a bearing going bad giving you the "Rod Knock. This is more serious though. If the thicker oil fixes it - don't go too thick - you may be okay for quite a while. If it's bad, it's better to get it fixed - not cheap, but far cheaper than a new engine.
Take it easy on the engine - warm it up a minute after starting, drive it gently until it's up to temperature, keep up with the maintenance, and don't abuse it and it'll last a long time - I've got overmiles on my pickup, hassle free. I'm more worried about rust than I am an engine or transmission wearing out.
I personally know of 3 f's with the 4. If it is rod knock, is it typical for the engine to last this long without blowing a rod? Does anyone else have this problem with their vehicle? It's a '98 with less than 60, miles. This is also not a normal sound that an engine should make. Answer Save. Try some thicker oil. Good luck Been there. It could be a couple of things How do you think about the answers?

See all problems of the Ford F Throttle body failure: first occurred on original throttle body oem part in Vehicle was turned on and stationary in a parking lot. Heard a loud knocking, diagnosed at Ford dealership.
Replaced original throttle body with new oem throttle bottle. Second occurrence on replacement throttle body oem part in June Vehicle was in motion on an interstate, wrench light came on, putting the truck in limp mode and the truck stalled. I pulled over on the side of the interstate, turned the truck off, waited several minutes and turned vehicle back on.
Cleared the fault and was able to continue drive with loud knocking sound occurring like in the first instance. I just bought this from a dealer about a week ago and I'm very frustrated right now because I am working hard to make payments on this truck and now I probably have to replace the engine???

Making a knocking sound during cold start.Our Address. Kings Mills, OH Sounds like the noise is coming from the passenger side valve cover using a Mechanics Stethoscope is my best guess. Very tough! Here is what I have done to my F 4. Truck runs very good and strong. Ticking noise gets faster the more you accelerate. Turning the ignition key off, noise rattles down.
They are fine and tight. Too much of a tick for rod knock. Does seem like it is quieter when engine has warmed up. What grade of fuel are you using? Is it 87 octane or higher? Too high of an octane causes predetination and that sounds like a knock to most ears.
You can try pouring in a bottle of zmaxx to see if that loosens it all up a bit. It could be a little starved for oil if the oil galleys are clogged.
The 4. The most common ones to break at the ends of the heads. When you replaced the manifold, you should have replaced all the studs and nuts at the same time. Your observation that the noise abates with engine temperature really makes this the best logical place to start looking. Get some vise grips and start turning. Then you can weld a nut onto the nipple and wait for it to cool; And then, finally, you can turn it out like a regular bolt. You could have fixed the symptom at one end of the manifold and recreated it all over at the other end.
It happens. Exhaust manifold is not the problem.
I am very maticulus when I take something apart and put it back together. My profession is a Mechanical Engineer.
I had 2 studs break, so I welded nuts onto the broken studs with a mig welder. Was able to extract them with just a pair of pliers.This sound, like a low end bottom knock,meaning one of your crank bearing,s is weak,and should take 5 quart,s to fill it,first thng to know when you change your own oil,is never crank it right up,pull the fuel relay,and turn it over a couple time,s,this pump,s the oil on to the crank and doe,s not crank it while it,s dry,i all way,s do it to my car,s and trucks, no matter if old or new,speedy lube dont even do this for you,but it is bad on any car to crank it,with out doing what i said.
BoholMark answered 5 years ago. Did you fill the filter with oil before you installed it? I hope you did. Check your dip stick for the proper oil level. My truck was driving fine a week ago,I park it in driveway,go inside ,come out the next morning get in warm it up put it reverse and won't move,put it in driveway same thing.
The only difference I fill both tanks but my switch doesn't change the tank it comes out of the back tank only even when I push the switch to c This started a couple of weeks ago and the ticking did not seam so bad it is now getting louder specially when I give it gas.
It is sounds like the motor and I can't tell which side. I am a woman and Yes the power steering fluid is full, and it only whines a tad bit when moving the wheel while sitting still.

It was first thought that the cylinder needed to be replaced. Fast forward 3 weeks and the truck was ready to be picked up with the new engine installed. The very next day 3 new issues appeared as I was driving down the highway. The check engine light, check engine oil pressure, and the adaptive cruise control. I took the truck back in and left it with Ford for another 4 days and pick it back up after getting a call that it was ready.
I noticed the check engine light was still on as I was driving it off the lot so I turned around and notified Ford. I made a 3rd appointment for them to fix this and am currently waiting to see if the problem is fixed for good.
I have a F which is my fifth new F I've never had so many problems! Half the time at start up it clunks really loud, sounding like the rear end is falling out.
F 150 knocking noise coming from bottom end of engine???
Its so loud I've had people walking by so startled that they jump and give me a dirty look. My biggest complaint is the engine noise. It actually sounds like a diesel engine most times, so bad that I've been asked to turn it off at a drive thru window so the guy could hear me. I took it to the dealer I bought it from and the other 4 trucksthey had it for a week just to tell me what I'm hearing is "normal"?
The new Dodge Ram is looking pretty good now, or any truck that doesn't have so many problems I'm planning on taking it back soon to raise some hell with the service folks, can't blame them totally since I'm sure they're just following orders If you have a for-profit service, contact us.
