Recently my Max has had a slight ticking noise radiating from the engine. I am having a hard time locating the sound, and I'm pretty sure that it is not the water pump and positive it is not the belts. It seems to be coming from the area around the fuel injectors. I am having a little smoke coming out, but it smells like it's just burning rich from my fouled LH O2 sensor. I am just not sure if I have a DIY or something major. Any advice would be helpful.

Thanks

 

not to worry its kind of a nissan thing, valves or something like that i read once i think.

i know that once i started putting in premium fuel 92+ i almost cant hear the ticking anymore

 

It just might be your injectors also. Take a screw driver put the tip on the injector and put your ear to the handle. You should be able to tell if the injectors or not.

 

Get a 30" long piece of fuel line or rubber hose. Stick one end of the hose in your ear. Then aim the other end at different parts of the engine to see if that's the source of the noise.

 

I've got that tick tick thing too....It sounds like it's prolly just a valve tap, lots of cars do that, I know my cherokee did...if you find out exactly what it is please post so that I will know too...if it's something major I'm gonna get it checked out....thanks

 

my car makes a similar noise.. but its near the belts. Could it be the belts? Its kind of a whining noise? I tightend them.. but still samething!

 

that whining noise that you are hearing is most likely coming from your alternator. It is usually a sign that it will have to be replaced soon.

 

i just had that recall done.. so i don't think its the alternator. Maybe water pump?

 

mine as always done that. That is the VQ technology in action! Mine ticks louder in the cold. But it is always ticking if your listen.

 

what? what exactly is VQ technology?, remember I'm new to maxima.org so please be nice.

 

another silly question but I'm gonna ask it anyway...what exactly was the recall for? and where can I find out about recalls on my car and what has to be done? I have a '99 maxima SE-L. please let me know...thanks

 

I'd look into it being some type of timing chain tensioner problem. Do a search.

 

Your engine is code number VQ30DE from Nissan. The most powerful reliable nervous electrifying engine form it's generation and it's category. Well at least I like to believe that. Perhaps many members here do to.

 

Hey guys I just had a fuel injector flush performed at the dealership today .. and suddenly my car is ticking worse than ever.. sounds like the front three fuel injectors! Do I just need to wait till the cleaner burns out of the system? or do I have a problem?

 

Yes I know the feul injectors makes a ticking noise, another ticking noise may be your IACV. Try disconnecting the harness while the car is running and see if it stops. My IACV is currently possessed by a mythological beast and ticks even when the engine is not running.

 

You may want to check the IAC valve (Idle air control valve). Mine would tick while the engine was running and whille the key was set to ACC. You may want to remove the IAC and clean it. The valve may be sticking a bit.

 

my bad engine makes several ticking sounds...one is normal, not sure what causes it but you hear it after turning the engine off as it cools down....the other are the lifters and the timing chain tensioners....gettting a new engine!!!

 

are you getting check engine lights for the ticking from the iacv?

 

the ticking you hear is the injector selanoids it's nothing to worry about, like that others have said, VQ tech. at it's finest

 

Im getting an error code for the iACV so i wonder if i should clean or just replace.

 

CEL diagnostic trouble code 1946 is defined as "IACV ticking too loud" if you pull this code, your engine must be replaced immediately.
