When i accelerate at LOW (0-30) speeds i get a clicking/knocking noise coming from my engine. It isnt very loud, but i can hear it. It steady makes the clicking/knocking noise while i accelerate. I cannot figure out what the hell it is. Does anyone have ANY clue what this could be?? any help would be appreciated...

 

bump.................

 

I get the same noise... anyone have any ideas? It happens quite frequently... almost sounds like there are rocks or something that are caught in a catalytic convertor shield or something..

 

I sometimes hear it too...maybe check your heat shields to see if they are rattling on anything. It's a start at least.

 

i hate the noise but I just got used to it.....it has something to do witht the exhaust but don't know where......

 

not a clue man.. auto or 5 speed, i can't even begin, more info

 

what type of y-pipe do you have? I have a 1st gen stillen y-pipe that came with a smaller flex section so it banged against the brace/bracket near the catalytic converter area when accelerating

 

i always assumed that it was the valve train. i thought it was lifters tap but i rememered we dont have any. maybe nissan makes a bad head setup like the bad tranny's

 

yeah i have an auto tranny. I thought it was something loose in the engine. I also assumed maybe i was driving over some rocks...haha I honestly have no clue where the noise is coming from. I hope its nothing bad. Any ideas?..anyone...

 

I have the same problem, only happens during full acceleration. Nissan told to change the coils, I did and seem to be ok for a couple of days. I jus heard it again the other day. What to do????

 

how many miles you got on it? i know when i got the same clickin on mine at 128k miles i had to replace the timein belt upper and the lower one but a clickin sounds more like a header leak have you checked that?

 

what kind of gas are you using? make sure that you use higher than 91. don't forget to check your oil level.

 

A 3 year old bump huh... lol I wonder if he's still having the same problem, maybe he'll chime in. I think it's definetely rocks in the tires

 

Motor Mounts??

 

man i just noticed that too back in o4 dang

 

I got 80,000 miles on mine. I use 93 octane for past couple months, the clicking seemed to not be as bad once I started using 93 octane. Brand new nissan coils were just installed last week. Havent been on the highway yet since I installed them.

 

it may be your cats breaking up and ratteling under light acceleration withing the catalitic converter housing.

 

U talking bout the precats that r on the y pipe?

 

I feel that nissan's engines have very loud valve ticking noises, not just VQs.

 

precats they go...
But this post refers to nemmehs one. they tend to rattle on light accel not heavy. They won't click or knock
Your noise could be a number of things... Should get it looked at, probably a motor mount or something...

 

ok, well thanks anyways.
