Random Rattle/knocking near header area Ques for eagle

[mr.gto]

So after driving the camaro for a while we noticed what sounds like an exhaust rattle/clunking back and forth at idle because of the motor shake. It didnt do this right away when I put the motor together it just kinda started more and more. When I put the car in gear or reverse and its on load the noise lessens and almoost goes away. Also while driving the noise is not there.

Car shifts fine seems to run ok, so I was wondering could it possible be just the exhaust rattle and clunks or could it be in the new 3600 i just installed? I havent been able to get under the car yet so I know eagle had torque converter probs Was wondering if it sounded like this.

If this is just for Eagle...PM him....

 

[mr.gto]

well its for everyone also.... i just know eagle had some problems to before

The converter should not make any noise if its working & installed properly. Did you need to shim at all? Spacers?

Exhaust is very likely, but should also be VERY easy to find/isolate/correct.

Do you scan or data log the car when you're driving around? If so, anything odd in the scans? If not, start scanning now just to be safe.

I'm sure others will have input as well on this one.

Didn't you say you and Brandon thought this was a problem? But you found it was a collapsed lifter, maybe it wasn't what you thought? You never know. Hope you find the problem isn't anything bad!

We didnt see anything wrong when it was at fast motorsports...... however it has a TCI flex plate now and when I was bolting up the new SS 3600 I wasnt able to use my new ARP torque converter bolts because the head was to tall it was hitting the back of the cam plate bolts..... the new ones Yank had on the converter looked more like stock and cleared them ok. I found that odd and very distrurbing. But the converter was all the way back in the trans, it went down once.... I rotated it around and it slid down again and I filled it with over a quart and a half of fluid before it went it.

this is a different noise a lot quieter than that loud noise we heard lol! This u hear when im cranking the motor when its vibrating back and forth, and then when its in drive or reverse the noise stops clanking

hrmmm... did you by any chance measure the clearance between the TC and the flexplate with the TC seated into the trans fully? I think there is a max spec for that measurement - otherwise you need to use spacers or something.

If its in park/neutral and you add 100RPM or so, does it change or go away entirely?

when i add rpm the noise lessens because the motor doesnt shake as much..... and i belive the converter is up against the flex plate.... but 262 when it was in the air and we were checking bolts didnt say anything bout it

 

[Eagle]

You measure without the two bolted together. So unless you took out the TC to flexplate bolts you wouldn't have been able to tell. The bolts not clearing the came plate bolts doesn't sound right to me at all...

well the arp bolt heads were a lot taller than the stock ones

 

[mr.gto]

just talked to yank they said they have heard about the arp bolts being to big from multiple people using different converters. That they would have to shave down the head.... so that issue is normal I guess

 

[Eagle]

yea yea, I get the head of the bolt issue - but I was more referring to measuring the clearance between the unbolted TC and flexplate.

well i guess we are going to be doing that tommorow...... lifted it up and it spit out every single torque converter bolt.... yes thats right there were none left. so were prob going to be retapping the converter holes tommorow and putting the arp bolts in since there longer and better for the TCI flexplate..... we shaved the heads of them down 20 mins ago. Im so pissed and depressed. We just got her running and now this. I thought these bolts looked a little short when i was putting them in, and I torqued them to. Thats prob the noise we heard on the dyno at deans.

 

[Eagle]

Yea dude... you're probably lucky that its just the bolts. Sometimes the flexplates tear the center out around the flexplate-to-crank bolts.

You might check and make sure that you have the correct flexplate, that your clearances between flexplate to torque converter clearances are within the specified tolerance, that your flexplate did not get bent or damaged, and that your input shaft on your trans is ok too...

Make sure you use loctite on the the new bolts to the TC too.

Good luck man.

It's the right flexplate. Just the tci one. I am curious it came with the flex plate and the bolts and this black circular piece that looks like it would fit in the center of the plate like a centering tool but it's to small..... What is that piece? I just left it out because no one could tell me

 

[mr.gto]

That little black thing off to the left.....

 

[Eagle]

No idea actually. The TCI I have in my car for the TH400 didn't have such a contraption.

I know.... Some pics of people selling it had it and some didn't so I just left it out it didn't fit anywhere that I could think of.

 

[skeezer]

Looks like a spacer.

 

[HILROD]

It goes between the converter and crank pilot hole. It's not used on all applications. If the converter goes into the crank tight it's not needed.

Called tci. They said it's not used for my app. They Said it's an adapter for different apps

[mr.gto]

Now I'm just worried about retapping the converter holes
