Knocking getting worse

Why are you just showing a picture of your truck in the video? If the noise is coming from the engine why not jvideo the engine?

its really not a video per say it is an audio recording with a pic behind it, so it can be listened to.

Does not sound good

I have about 13,000 miles on my truck and it's starting to sound like this. I will be taking it in when I hit 15,000 for it's oil change, and inquire about this noise. Glad I purchased 7 month 100,000 miles extended warranty. Good luck, keep us posted.

Really, wow :thatswck:I thought that I might be an isolated case. Sorry to hear that. I can very much understand how you might feel about it. Mine became noticable at about 500 miles, I think it is piston slap. It could be a rod knocking too, both suck and are unacceptable. I also have the 7 month 100,000 miles extended warranty, but it does me no good if they don't fix it. The dealer should have taken it back, but the suck egg mules would not help me out. Good luck on yours as well, let me know what they find out.

Dude, if mine sounded like that I would bring it to the dealer sounding just that way and say...If this is normal, you take it!!! ...and walk away!!!

I don't care if it is a pic of the truck, a bird, a dog, or whatever for that matter, just sounds bad!!! Put on your armor and go to battle,...nicely!!!

My truck sounds nothing like that. What part of the engine are you holding your recorder to? It sounds like my old Mazda B2600i, if I let her sit for a couple of months. It had a weak oil pump.

I would try switching to Valvoline Premium Conventional Oil 5W 30, and the Nissan factory oil filter. I run that combination in my truck, and it's as quiet as the day I drove it off the lot.

I used Mobile one and Valvoline full synthetic for a while, and I noticed extra noise that made me switch back to conventional oil.

I should mention that this is at a cold start up, however the knock is still there only muted somewhat, when warmed up, sort of makes a clucking sound. It can at times have a vibration, which feels conected to the sound. This coming week it will be fix it or I may look into legal action of some sort, it is really getting on my nerves. Looked at a Titan the same night, wish I'd went that direction.

Did you ever have the dealer run another 4.0 motor next to yours? I personally wouldn't have let it go this long. Go there and DEMAND a Nissan North America factory rep come listen to the truck. Make them either replace the truck or the motor but nobody else has a motor that sounds like that.
Go get an independant engine builder to listen and write their opinion on the cause and pay him for it. Then take that with you to the dealer who "can't" (doesn't want to) hear it.

At the time they didn't have any new ones left. I have had a friend of mine which has workred on cars for many years listen to it and he thought piston slap. I sent the same audio to the dealer for them to listen too, several days ago, and have had no response. Thats why I am looking for another dealer. I might trade it off for a Titan. I found 3 about 2 hrs away that look very appealing. Your right though they really should replace the truck. A new motor would destroy the originality of it IMO.

Don't they have a Pathfinder on the lot? I think the Xterra has the same motor too. I had a Titan for three years and it was great. You will take a bath on a trade so a Titan trade will cost you big time. Call Nissan North America and nicely complain but ask for the regional rep to contact you.
You can mention your attorney is waiting to see what they do before he gets into the act and makes it a public issue.

Mine doesn't sound that bad, but i still get that slapping noise for about 5 minutes in the mornings at cold/dry starts.
My dealership just replaced the timing chain and put in conventional oil, so we'll see if that makes a difference.

They sould you would think have one or the other. My biggest prob is it is 70 miles away, & I have to take off work. If it were close, you better beleive it would have been resoloved by now. I'll call Nissan, but I am going to call my dealer and see if they ever listened to my recording first. Yeah I know I'll get my butt burned on a trade, but it might be worth it in the long run, and I REALLY liked the Titan when I test drove it, but I listened to my wife as she thought it was too big.:censor: anyway

I had two Frontiers then the Titan and back two two Frontiers, and since the last two were the larger second generation I feel like they are plenty big enough. At times the Titan was too big. With the towing mirrors I could not fit through the banks drive up window, filled a small parking space when opening the doors it was an issue and it drank gas like you may imagine. I never saw over 16 mpg's highway.

There is currently a TSB out for a noise in the engines on 08-18 Fronties. There was a problem with the timing belt tensioners. Just FYI. Get it to a dealer and have them check it out.

I listened to my engine this morning and it does sound that bad. When the dealer fixed my timing chain they used conventional oil. Maybe the synthetic, even though its the same weight, is thicker. Is 0w30 thin oil compared to 5w30?

that sounds like a rod knock. its too slappy for a lifter. it may be a piston slap but i think it would be louder and have done more damage by now.

After church this morning I had my Pastor, who was a service manager at dodge for years take a listen, along with another friend, and they thought it could be the timing chain. With that as a known prob, maybe so. Any Thoughts?

I know you said you lose work time but the truck has to go back to a dealer.
Make sure it's CLEAR (they play stupid, and do a good job) you need to be seen first thing so you don't sit and wait to have it looked at. Your time is valuable too. They may have parts in stock and give you a loaner car.
I know it shouldn't happen in the first place but they will make it right and you
and you'll be happy again. They need a chance to make it right.
Even if you want to trade it for a Titan, get it resolved first.
I wasn't happy my Pathfinder needed the repair but they did a perfect job and cleaned the engine bay too. Looking under the hood you would never know the engine was apart. I saw the engine stripped down to the heads and block only. Every single wire, loom and part is in it's place, clean like it was never touched and most of all a year later as quiet as the day I bought it.

Hey Red brick, I will try to get a copy of the TSB tomorrow and get it to you. Maybe with it in hand you will have more luck. Sorry about the problems you are having with your dealer.
