Ticking comig from Engine at Idle

[AirMech]

Hello,
Newmember here so please go easy. Just got my Titan last Friday and love the truck. My only concern at this point is that after 100miles I'm now hearing a ticking sound coming from the engine near where the valves and liftes should be. Saw on an earlier post that someone had mention the same noise, but nobody seemed to have an answer? If anyone could please enlighten me that would be most helpful.

It's hard to say exactly what it could be without hearing it myself. It could be lifter tick, sure. It could also be a small exhaust leak, it could be belts on the pully system. If you can isolate it to the valvetrain area under the valve covers, you might wheel it into the dealer to get a confirmation.

I have noticed the same on mine. I hear it when I am in the cab, but I do not when I am standing outside listening for it. Hopefully this is just the sound of a strong motor, gotta remember there are 4 valves / cyl.

Right now the only minor concern I have is with the exhaust heat shield under the passenger side is a little loose and vibrates when I am accelerating, atleast that is what it sounds like.
I will be taking it in to the DLR here soon, I just hate to part with it.


My 98 Sonoma Stock muffler had a heat shield that did the same thing. Cut it off and the problem went away.

I am still hearing it as well. Its definitely coming from under the valve cover area. I am at 1000 miles and will be taking it to the dealer at the end of the week for an oil change so I'll ask about it then. I do not seem to be having any loss of power or anything though. I would reccomend calling Nissan and registering the complaint. The more they hear about it, the more likely it will get quick attention. 1-800-Nissan1

I also have a loose heatshield. The dealer will be tightening that up for me too.

You may want to also check your tire pressure. It seems Nissan shipped the Titan with 44 PSi in the tires. They are rated for this, but the manual reccomends 35 PSI for the Titan.

Cheers,
Jeremy

Hi Jeremy

I found out that Nissan puts 44 PSI in the tires to stop the vehicle from bouncing on the "mobile parking lot" when being shipped. Just came in, my King Cab LE arrived today.

4x4
Big tow pkg
Air bag pkg
Running boards
Fosgate 6 changer 350 watt
Gated Shifter
Leather Captains chairs heated
Utilitrac system
Sprayed in bed liner
Fog lamps
Daytime running lamps etc etc I LOVE IT!!!!!!!!!!

More air equals LESS bounce?

Thanks for the info Camp. Your new truck specs look awesome! I was gonna hold out and save money for the LE, but I was too damn eager! I figure I'll keep this one for a few years and then get an LE.
Cheers,
Jeremy

Well if you increase tire pressure you get a firmer ride,right? Soooooo, by inflating to 44PSI when shipping you get less "bounce", "movement", "shake" see where I'm going?

Have a good one, and hope you get your truck soon!

Firmer means more rigid to me. Since I let my tire pressure down to 35 it actually seems to ride smoother IMO.

Thinking more about this tick....
I stopped by my mechanic to have him work on my other vehicle and asked him what he thought about the ticking noise. He said it sounds more like injectors than lifters and that this noise has appeared on others cars when they are new. He thinks it will dissipate as the injectors wear in. More to come when I take the Titan in for its first oil change at the dealership

Mine has a ticking sound too.

for the umpteenth time. The engine in your Titan has NO lifters. The design uses overhead camshafts, this positions the cam on top of the valve, with an adjustment shim between the camshaft and the valve stem. It is IMPOSSIBLE to have "lifter noise". What we are all hearing is injectors opening and closing. Welcome to the modern engine. This ain't no steel pushrod pre-war engine. Relax, the noise is totally normal. The fact that the thing runs so quiet and smooth is to be credited for why you hear the ticking in the first place.

Good call, Skip. I didn't even think about that.

Hee heh ha - Skip rocks.
sorry, as you were...

Skip, .........THANK YOU. After reading your reply, It all sorta just makes sense. I guess I'm just stuck in the stone-age, but if anything it's taking alot of worry that's been on my mind and allows me to enjoy my Titan even more.
