Engine ticking
#42
OP, as far as the ticking noise, can you hear the ticking while inside your car, revving or idling? and if so, is it barely audible or is it something you can def. hear even with the windows rolled up?

I know this is really late response, but... I didn't miss a downshift, but there were a few occasions where it didn't fully lock into a gear and stepped on the gas. It made a metal screeching noise...

I have a very similar (if not identical ticking noise on my car) it has been about the same since I bought the car 10,000 miles ago.
I've had people tell me its just lifter/valve noise nothing to really worry about. Performance of the car has not changed at all. Used quality synthetic oil during oil changes with no change in noise.
I am changing my belts in a few weeks, I'll post up if it makes a difference like the other guy mentioned.

Hey. So I'm in a dilemma. I have an 03 350z with only 22,000 miles. I've been hearing ticking noise coming from the engine, but haven't really found any solutions online. My mechanic states that it is a valve issue, which I'm hoping it isn't since I'm out of warranty. Some told me it's because I'm using thin oil and some say it's normal (which I doubt).
So here's the rundown. I contacted Nissan corporate and informed them of my situation. They advised me to get a diagnostic from a authorized Nissan service center and they may be able to help. Dropped my car off and after a few hours, mechanic advises me that it may be an issue with my exhaust valve and it seems like it isn't affecting my engine.
FYI, I only have 27k on this car and this prob started around 15k miles. yes the car is out of warranty due to the year of the model, but really?! I pampered this car and took great care of it. Shouldn't an engine start having problems after 80k (this is being fair)? Does anyone have ideas to expose their BS quality?

22k miles over 9 years ends up being around 50 miles a week. But it looks like more recently, you jumped from 22k to 27k miles pretty quickly based on your posts. Is the car sitting during the certain months and driven during others? Or has it been sitting unused for a period of time and you're just now starting to use it again? Were you still changing the oil every 3 months regardless of mileage? If not, what was your maintenance schedule?

It looks like two different mechanics have told you that it's a valve issue...

Sorry for the bump, but I had to chime in a little. I discovered an audible tick when the motor was warmed up a few weeks before Thanksgiving and have been trying to figure it out. The motor has been whisper quiet for a few days now and what has worked for me was a bottle of Redline Fuel System Cleaner for a tank followed by an ECU reset by using the gas pedal method. I figure why not. It could help clean carbon buildup and the ECU can adjust itself to the valve timing. I'm not even sure my '05 has variable valve, but it seemed to work for the 37s with the same problem. What also could have contributed was making sure your coolant system is properly bled. During the week I remember having the car idling on a incline with the heater on enough to have the fans come on a couple of times. If it was indeed the cooling system making noise that may have helped. I noticed that the overflow bottle had lowered itself a little bit into the normal range since I purposely overfilled it an inch or two above the F mark during a coolant change also done before Thanksgiving. It seems like a mysterious phantom noise to me, but it has since been better. I hope it continues to stay that way. I'll continue to drive without the radio on lol

The coolant system making the ticking noise? Lol no. That's valve lash noise. Valve job or replace the motor even tho this is 3 years old now.
The 03 has a factory recall for the injectors making the "tick" noise as well. But his problem is valve train related I've had it for 10K miles. Doesn't hurt the car it's just a aggravating annoying tick.

I wouldn't let it bother you. No power loss, it doesn't consume oil, it's just a annoying ticking sound. I've looked into this for about a year now. You can do a valve job (roughly $4-$800) on your own. Or have a shop do it which is like $800 in labor plus parts. I know Nissan wanted like $2500? Or something like that to fix mine.
Or do what I'm doing. Find a low mileage DE motor pre 06 year and swap it in. It will cost about the same as getting your heads rebuilt.
Or just drive it and listen to the tick. I've had it for over a year and I'm finally fed up with it. It's making me not want to enjoy my car.

I find that my DE uses about a quart every 2K miles. When it starts to get even a little bit low, I find that the ticking gets more audible. It just sucks thatit's so f***ing difficult to accurately check the oil level due to the stupid dipsticks on the VQ35. I also know I have a minor exhaust leak from a bad gasket between the header and my TP's, and the ticking I'm actually hearing is the exhaust valves on a cold start. Once it warms up and everything expands, the leak goes away and so does the tick.
As a precaution, I also substitute 1 quart of my oil with Lucas oil additive every change. Consumption has gone down, and ironically, my compression improved too.
