What do these symptoms sound like?

[asephoner]

Hey guys what’s up I have been battling with this issue for a while with no success in finding what’s wrong however I know what its not. Which is cool.
What do these symptoms sound like?
Engine clicking sound during idle and acceleration really loud (not lifters)
And sort of a squeaking accompanying the clicking sound also very loud.

When in park car idles okay a little above 1000 rpms. When in drive car idles poorly wanting to bog and die.

Car is in really good shape otherwise and has no known mods

All things that checked out okay: alternator, oil pump, turbo, exhaust manifold, boost not leaking and if it is I just haven't found it, battery good, belts good. No smoke of any kind nor is there any fluid leaking from anywhere. Oil pressure is okay, oil level a little low but okay. No cracks found on any exhaust components.

So what do you think?

You gotta find out where the noise is coming from. If it's something clicking or tapping in the motor I'd head in the oil/lack thereof direction. Is your oil low? When was the last time it was changed? Change it and check for metal flakes of any kind.

Run 25% Lucas in there to thicken up the oil and see if the ticking subsides.

How are you sure it's not the lifters?

 

[asephoner]

I change the oil a month ago (about 300 hundred miles) 10w30 mobil fullsyn K&N oil filter, could that be a problem this clicking sound just started and when it started it was already loud and by loud I mean if you were lets say 20 feet away inside your house with the water running you can still hear it clearly. I would say it sounds kind of like a spray can rattle just more precise.

 

[weith1111]

Yikes! Well if you changed something, and then this started, I would undo that change. Put an OEM filter on and make sure you have enough oil. How's the oil pressure?

 

[robs90tsi]

Drop your oil anyway, and see if you have any metal shavings in it, because what your describing happened to my friends GSX when he spun a bearing, so drop your oil out and see if you have any kind of metal in there whatsoever.

 

[asephoner]

Will do.

So if I find metal it means, its time to tear it down or what?

 

[weith1111]

If it's the crank/rods, yeah pretty much. Especially if your block has over 100k on it, I'd just do a rebuild. Do you know how the compression is?

 

[asephoner]

No i haven't a clue what the compression is but I will try and find out before I drop the oil.

Thanks so much for all the advice.

If there is more I should know feel free to post.

If I have to rebuild it which direction would be best for those of us in the pocket pincher community Not to skimp on quality

if you are on a tight budget, get a n/t crank with the rods that come with it, as the 4g63nt's ted to be considered cheaper even thought theyre the same thing. my nt spun a bearing and i drove it for a few weeks before tearing it down. my friend changed the crank and rods out in one night so it shouldnt be too hard if youre experienced.

Could be a failing timing belt tensioner pulley.

I don't think I've ever heard it called that, since there is no pulley on the tensioner, but I think you mean the crank pulley, and if so, that's a really good suggestion. If that thing is falling apart it could be making all kinds of bad noises. Check that out ASAP as well, if it falls apart completely it could take out all your belts and possibly get into the timing belt.

 

[asephoner]

Nice! that would be a wonderful thing to have happen , Im debating with just replacing the darn engine, don't know if thats a good idea, Im mean I don't mind doing it because doing internal engine work is not something I'm real familiar with. I will try most anything once with some instruction.

 

[weith1111]

Don't get ahead of yourself, so far all you need to do is check the pulley and the oil and see if something is awry! Then go from there.

 

[asephoner]

Well thats what I'll do no need to do more work than I have to. the motors got around 96.000 on it I figured it may be in need of some sort of refreshing it is a 7bolt you know if I can make it permanent and hop it up with out worrying about moving cranks and so on I would like to. I like the 7bolt "but it may be a waste of time"

If you had ever changed a timing belt then you would know what I'm talking about. There IS a timing belt tensioner pulley. They can fail, and when they do they make a clicking, screaching sound. It sounds like bad lifters and a squeaking belt.

Wow Thanks I have never changed a timing belt before however I understand what your talking about. If the tensioner pulley is or has failed would the car bog and shut off?

HA!

I stand corrected! And I have changed a timing belt, a bunch of times (about to do another one here any day), but for some reason I was blanking out on it being the idler or tensioner pulleys.

I was set on you meaning the crank pulley since they go bad just about every 60-70k.

You are so very correct. Rep points coming your way

Okay for lack of time I just recored the sound and posted it on Youtube. Now I haven't had a chance to pull the oil out and check for metal flakes because of this off and on rain that we are getting here. And I'm sorry in advance for the shaking cam(I wanted to make it more dramatic ) actually it started to rain so I was really trying to keep the camera dry.

heres the link tell me what you think.

so no one has a clue what this is?

 

[sadsm]

I have a noise that is similar to that one coming from the same general area that yours is. Every one here describes it as two light bulbs hitting each other. I am pretty sure it is a spun rod bearing, but my jack took a break on me so I have to go buy a new one before I can check the oil.

If this is the case what do you suggest I do. I mean do I just fix the bottom end seeing as how the car hasn't completely failed "yet", or what.

 

[eclipsh]

Go buy yourself a mechanic's stethescope and give it a listen. It could be worn rod bearings resulting in rod knock.

 

[asephoner]

Cool I get to buy some tools

 

[eclipsh]

Yup. They run about $20 from Snap-On and will let you hear all sorts of scary sounds inside your engine and tranny. Use the metal rod insert to listen and have fun!

 

[asephoner]

so what am I looking for exactly.

Thanks to all of you by the way.
