whatcha think. iv got like 3/4 to 7/8" side to side.

new chain and sprockets on NON linebored block.

 

If I'm not mistaken, I believe the LS2 uses a chain tensioner. I may be wrong, but try typing "tensioner" into "search this forum".

 

they do, but i guess most guys dont run them when doing a upgrade... i called texas speed when my block was being machined and they said u dont need it unless your road racing. so i decided not to get it drilled for one

 

Hmmm, I can't say I'm familiar with that set-up, but it sucks that you're having problems. I, myself, wouldn't be comfortable with that much slack either. Anyway, good luck getting it sorted out!

 

thanks!

 

ide say no way in hell chief. I used an LS2 chain on mine and my buddys LS1 cars when doing cam swaps and neither were that loose. Ide double check and make sure you actually got an LS2 chain, or perhaps it was mis packaged?

 

it is, was bought off group buy from yank...and he says its because i dont have tensioner...

 

well, im here to tell you like Ive said, i have installed 2 of them and they WERE NOT that loose!!!!!! OH, neither had a tensioner either.

 

i know my buddies said same thing... scares me with thousands of dollars at risk if it breaks

 

ide order another one from sdpc.

 

Well crap, that's where I got mine at. I haven't installed it.

I deleted my last question. I re read the first post and saw it was new.

 

Wow! thats A LOT of slack! I just installed my LS2 chain, I was concerned because mine had a little bit of slack but not nearly that much. I was told a little slack is normal with these, but that doesnt look right at all.

 

i ran into a similar problem on my build, only it was about 1/2 inch of slack with a katech c5-r chain. I ordered a cloyes hex-a-just single roller, it tightened it right up and it had a heavier duty chain than the c5-r. The chain was, or was very close to an IRL chain

 

so do not run this? get a new chain?

 

The standard Cloyes Hex-adjust uses the Renold chain, which is the LS2 chain. Cloyes is the OEM manufacturer. The C5R is a much better chain. The IRL chain is shot peened and a different steel. It is also blue printed and hand assembled. Also, and Katech has posted this, there are imposter C5R chains being sold for around $50. They are not the same. You should also be aware that every manufacturer makes several chains in the correct pitch, but the quality is different on each one so the mere fact that it is a JWIS chain doesn't mean anything unless you know the actual manufacturers part number. Here is a link to more information I posted in the Gen IV section a while back. Timing Chain Discussion

In this situation, I would call Mike at Cloyes tomorrow. He can be reached at the performance tech line. I am thinking you need a new timing set to correct this. Even though you already have the LS2 timing chain, you can sell them fairly easy without losing a lot of money. If you want an absolutely bullet proof setup, use the Cloyes 3153-AL, which is the true IRL chain. Bring your wallet though. Lingenfelter is the only one I know that still has this set as they haven't been made in a few years. The IRL chain is made by Renold and was developed to solve the timing chain failures they were having with the Aurora engine in the Indy League. Here is a link to the timing set: Cloyes IRL Timing Set

You can also get the IRL chain separately. Cloyes actually has some left in stock but don't send them to their vendors. You can get the chain if you call. There is a good thread on this in the Gen IV section (the link above is one of my posts in that thread). I don't think the chain alone with solve your problem though, you should get a matched set.

One other note. If the center distance is wrong between the crank and the cam bearings, you may have issues with the block itself.

 

^^^^ I agree with Bob (Vettenuts) above. His posts and research led me to the Cloyes 3153-AL setup. I just installed it and boy....there is no slack in that setup....I was very surprised after reading all the loose chain posts!!

I would not run that setup as is....to me that is asking for trouble.

 

yeah i thought it was to loose also... to much invested in this shortblock and engine to gamble with a loose chain

 

Wow, I did not have near that much play/slop in my LS2 chain. I just finished a few weeks ago and no way in hell I would have let that slide.

 

so should i try to get a new one from yank..or just go to dealer and see if they will swap me? its new...0 miles

 

Pro-Gear also makes good stuff. Well made and accurate. Pro Gear Timing Sets
