thanks Red MX5 and Billman. Yeah I knew something was wrong hence the reason why I didn't go drive the car. I just thought that when its in there, its expand anyways so thats why I bolted it up and didn't think of anything else. Well i hope nothing is majorly wrong or else it would sucks.

I'm actually a little worry when I go drive the car and hit vtec tomorrow. I hope nothing goes wrong but that would be the real test to see if something were to go wrong I guess. I can't be afraid to drive the car or else I won't enjoy it.

Does anyone know if the S2k is an interference or a non interference motor? if its a non interference motor then if the chain do break, it won't hurt the motor. If its interference than it will do damage. Anyways, I'm crossing my fingers when I go for a drive tomorrow.

I actually drove the car around the block when I installed it correctly tonight and nothing really seem to be out of the norm. I do have a slight rattle but thats probably due to my test pipe having a crack near the o2 simulator. anyways enough of me rambling. hope to hear from billman soon or someone knowledgeable

 

S2k motor is a MAJOR interference motor. It will easily break/bend valves if the chain breaks.

If the noise went away, you are likely going to be ok

 

Just throwing my experience in here for ya... When I replaced mine, I did the exact same thing you did, silvermonster, I set the TCT in place and before thinkin' about it, I pulled the pin out w/o bolting it in place... And yep the thing went everywhere... Of course now I never started my car at any point, I just got ALL the pieces back together, finally got the piston retracted and the pin reset after like an hour struggling with it, put it back in place, bolted down securely this time, and pulled the pin like normal thru the maintenance hole and the piston engaged properly with no problems...
Of course now I'm concerned that the new one MAY be on the skids b/c of the familiar noises associated with this part...

Basically, if you reset and reinstalled everything properly, which it appears you have done now, you *SHOULD* be ok with driving and VTECing... Keep an eye on your oil level always...

 

thats good to know that the S2k is an interference motor...damn it. Anyways, i drove 200 miles over the weekend and I think i'm okay. Been checking oil and its all good. Maybe I got away with it. Don't know. I don't hear any strange noise except my test pipe which has a crack in its weld. I'm planning on putting the cat back on and make sure its coming from the test pipe and not something else. Thanks for everyone help in this matter, much appreciate. LOVE THE FORUM

 

Hi all,

I read every post on this subject and think I may have this same issue, before you simply assume that I do just read through the points below and see if you agree. This problem is frustrating my car has been to two separate dealers neither of which could diagnose the issue.

I appreciate the help here guys, I love my car but when I drive it now instead of the rewarding addictive sound of my intake and motor makes I get a fluttering rattle so annoying my car stays home in the garage more often than it should.



Sound is there if the car is warm or cold.

Sound is most pronounced at 3000 to 4000 rpms under accel and decal more pronounced at decal because there is less engine noise.

I always described it as a rolled up newspaper inserted into a fan but maybe Bellman

 

^ If you want to be sure, go buy an automotive stethoscope and listen to the tensioner. You can be really sure very quickly. If you're too cheap to buy an automotive stethoscope, use the poor man's version... a really long screwdriver. Put the tip against the back of the tensioner and put your ear up to the handle. You should be able to hear the clackety-clack of the tensioner clearly. If not, keep looking.

 

I'm trying to identify the noise.

Is the clicking of the tensioner a constant speed? Or does the clicking accelerate with the speed of the engine?

Does it go away sometimes and return, or is the clicking noise always there?

Thanks,

Jeff

 

Bad tensioner characteristics:

Varys with engine speed.

Can come and go at will. USUALLY does it at first start in the AM, and sometimes after a hot start after sitting for 10-15 minutes. I have also seen engines that do it constantly.

It is very loud. It's as fast as a ratchet, if you were to spin it around in your hand.

If you can count the individual clicks at idle, it's not the tensioner. Tensioner clicks are about 20-25 per second. as opposed to valve train noise at idle, about 5-7 times per second.

 

Someone mentioned something earlier about a possible link between synthetic oil (mobil one to be exact) and the TCT issue. I recently switched from Mobil One Synthetic (5w-30) to Havoline Conventional (5w-30 GF4), and have noticed that it seems to alleviate the problem on start up. The noise doesnt happen as often, but it is still there, especially on a hot restart, but its not as loud and gets quiet quicker.

Anyone else notice this after changing. I will keep updating you guys as the oil gets older and starts to break down.

 

Interesting. I've always used Mobil 1 full synth, for the last few years. I had the replace the TCT once maybe about 15k miles ago due to have the starter after-run noise, but since, its never come back and I've never thought about trying another oil.

I guess since the sound has been gone for awhile I just left everything as is.

Would be curious to see if theres a trend with Mobil 1 tho.
