ok I was at a stop light yesturday and all of sudden I hear weird (TIC TIC TIC ) noise so I took it to my shop and look at it it seems to be coming from the timing chain area .... could that be the problem or a new motor is in order by the way i have a 2001 so VQ30de-k wiith 170 kms

 

check oil level. It may need a new chain tensioner. It probably seized failing to put a load on chain. Either way you wanna fix ASAP.

 

That sounds serious man i wouldnt drive it as much till you figure out what it is. Deff check the tensioner.

 

could be timing chain clatter.. there is a tsb out there on it....a tick tick could be alot of things depending on where its comming from

 

as stated above, check your oil level and/or timing chain tensioner.....don't go buy a new engine just because you head a noise

 

not to thread jack.. but how would u going about checking the timing chain tesioner? and how would u go about fixing it..

 

just what I was thinking how to check the tensioner

 

also should I change the chain tensioner and water pump at the sametime..???

 

I think my car just started making the same noise i checked the oil and its fine. I m not sure how to check the tensioner but i have change mine on my 4th gen about 2 years ago and dont really remember making that ticking noise.

 

I think there is a buletin for 3.5 vut for start-up though 2 seconds... Can't remember if there is any for the 3.0
tensioner is internal.
Side cover has to come off and if it is coming from timing chain area, you need a good inspection after side cover comes off,inspect/replace timing chain guides (slippers) tensioner etc. just to give you an idea
Get it looked at by someone though

 

the thing is all of a sudden it started making the tic tic tic noise like marbles are rolling around behind the timing chain cover .....I that likely to happen if the tensioners are due to replace ..??? or the noise would start to get louder and louder as time go by...???

 

ok I have a oil consomtion problem so with tha in mind I've decided to change my engine i found one with 77,000kms on it and I will also do my clutch while I'm at it

I will be doing the job myself ...so my question is is it easier to drop the tranny and engine then seperate it to do the clutch reassembly and put back in the car ...???

 

i never got around to taking the cover off . how loud is the ticking on your car chico ? the tick is quiet in mine i m not sure if its the timing chain. has anyone had this problem.

 

^ It's a loud ticking sound. It's just like chico said, it sounds like marbles rolling around. Mine just started making this noise 2 days ago and its astonishing how loud it was. I had never heard it before, but i knew it had to be timing chain related based on what people have described on here. I have a mild oil consumption issue so I added about 1/2 qt. of oil and it seemed to help a lot. It's hardly there now. Time to do some on the subject.

 

Does the noise go away as the rpms rise? If so, excellent odds it is the tensioner. Had the same problem with the V6 626 I had. Sounded awful, almost like an engine knock. When the timing belt was replaced, there was 2" of play in the belt.

 

I hope its not a timing chain that sounds like an expensive job.
