Holy f'n crap valve train noise

dandy · 03-18-2004, 03:44 PM

Hey guys, looking for somre info. My truck has a serious valvetrain clatter, and it quiets down after warming up. However when cold it rattles like a damn diesel. I also hear that purge valve after it's warm at idle. This seems strange so before I take it to the dealer any thoughts? It is in the valve train for sure and is way to loud for a 4 cammer. The tap tap taper has 750 easy miles so far. I'm freakin out

Its normal and since i changed my oil the valves have become much quieter. The purge valve is so ridiculous and embarrising when you have the radio off and you sit in your new truck sounding like its on its last leg. So change the oil and you may solve half your problem.

Whats the purge vavle sound like? When does it happen?

Well the purge valve sounds like a ticking noise coming from my dash, open the hood and it sounds like a very loud tick noise (would of thought it was lifters but we dont have them), but it you hold the hoses it will stop, they say they need to add some oraface to it so it doesnt create a vacuum. Thats just what i was told, i couldnt tell you any thing more then it shouldnt sound that way.
My ac makes a sound much like the sound the bag makes when they bag a patient at the hospital, or one of the breathing machines. Makes it every minute or so. Very strange i think it occurs about the same amount as my old ford truck used to click when i ran the air in it. So i gave up one sound for another.

I don't know if it's the same noise I hear, but mine doesn't sound like valve clatter... You should NOT be hearing LOUD noises from the valvetrain.

I hear a VERY pronounced ticking, varying with revs, worse the more throttle that is applied. IMHO, it sounds like an exhaust leak. It's been to the dealer ONCE for it and they turned up nothing. I don't think they checked it out, honestly. I'm going back again. It's ridiculous. It sounds like pinging, but isn't. It sounds like it's coming from the floor in the passenger area and in unacceptable in my mind. The dealer last time told me it was the catalytic converter and was meant to do that. Umm, I don't buy it. It's also gotten worse than it used to be... That is my one BIG complaint with my truck.

Thanks for info guys. I still have the noise, Its not the purge valve as Ihave that noise also. Last night I took a ride to check it out. After about a 30 sec warm up, with it still running on cold start up I listened no noise. Then went for a 4-5 mile drive , the motor was at operating temp, the tranny still cold. I could hear it at lights when stopped. Then I pulled over popped the hood, it's loud as hell. So i'm thinkin injectors maybe? If that's true these are the loudest damn injectors I've ever heard. But the motor runs so damn good and the noise does quiet down after long runs. It just doesn't seem right that a high tech cammer would rattle like mine does. I will take it to the stealer for an oil change and report back. Thanks again.

dandy, at first i thought you had a typo but then just started to laugh, you're right with the name. mine too has a loud pronounced tick, but i remember my friends tundra had the same tick. i'm guessing its a twin cam thing? dunno. but i love my titan... i will be taking it in to the stealer for an oil change too...

dandy · 03-24-2004, 03:37 PM

Well Im back from the stealer. I set up an appointment but that wasn't easy. I tell the service writer about my issue and he wants the truck at the shop at 7am on a work day. No sat hours. So just to get it looked at I swing by around 4:30pm after all I have to work all day to make the payments Ya know

They send out a 18-19 year old kid to look/listen to it. He does agree that it sounds kinda of loud. So we go for a test lap. He then states they all make this noise to a degree and when we get back, he fires up another titan. It too has the noise just not as loud as mine. If it made that noise when I bought it or a couple days after I would take it back. No way a 33,000$ truck should sound like that. I wonder what it will be like after its paid off??? So I will change my oil(Ibought 2 filters while i was there) no way that kid is doing it. I see myself at that age and say HELL NO! I will report back after the weekend. All I can say is this is unacceptable, If it continues I will be looking to trade it.

What model do you have and when was it manufactured? How long have you had it? How many miles total and how many were on it when you noticed this problem?

A: can I remind you this truck was designed from the ground up, BY HUMANS!!! stuff will happen, and you have to get used to the fact that you, the consumer is the guennea pig

B: Getting your oil changed by a 18yo is no worse than getting it chagned by a 35yo oil lube tech.

C: Your Stealership has about as much knowledge and experience with this V8 as you do. Nissan has only offered ONE class for this truck to the dealerships, and that was if you were lucky enough to get in line to fill it up in a two day period! Nissan Tech line is getting plenty of calls on the noise, which in your case is prob the purge valve.

D: your warranty is good, they just need fixes... then mass produce them. It DOESNT HAPPEN OVERNIGHT

Hey, let's not all start taking a crap in a box every time we have a problem...LOL

My suspicion (might be way off) is that some folks have cracked exhaust manifolds. If you have a loud ticking that goes away when the engine gets warm, that smacks of a cracked manifold. As a cracked manifold heats up and expands, the crack closes and the sound disappears.

Toyota had a significant problem with this on new Tundras. They were coming from the factory with the manifolds over-torqued, and cracking.

To see if this might be a problem, start your Titan cold, and listen on either side of the engine. If the ticking is one one side, try to listen and see if it seems to be coming from the area of a manifold. If that seems to be true, take it to the dealer and specifically mention the manifolds.

HS, when did Tundras have this problem?? Was there a recall? Source of info?

I can't remember if there was a specific TSB on the problem. However, at TundraSolutions.com, it was a pretty common problem that members reported. I couldn't tell you what years were affected, aside from 2000 Tundras. My guess is that Toyota fixed it in more recent models. My dealer was aware of the problem and fixed it quickly with no hassles. Search Tundrasolutions.com for it if you're interested.
