    @TravAZ well I'm pretty sure I saw the that slack 3 days ago when I had it open but thought the same thing maybe Motor was at a certain point where there would be some slack but what are the chances of it happening again and would explain why the sound/slack goes away once the chain starts spinning a little faster it gets tighter and doesn't slap once it slows down the slack picks back up and starts to smack against the guides I'm assuming gonna change tensioner and hopefully no more issues my idle is still fine and I'm assuming it would idle terribly if timing was off and also I have no check engine lights

    So pretty sure I figured it out so do I have to reset timing . Chain is lose and slacked tensioner either failed or never activated. What's my next move guys ?

    @iNewton thanks a lot to take in. Goin to take valve cover back off and make sure i did see a little slack in chain. This has made this sound from beginning using Aries Pistons not to sure the exact specs and which metal they used. Was built by alpha who ever they used for engine rebuild. But my sound also goes away once I hit throttle. Goes away once I past 1200/1300 Rpms I feel if I had my sling idle a little higher I would never hear this. The slightest little bit of throttle and will go away and I never hear it when on load or boost . And motor feels strong when boosting. Running 12 psi green and yellow spring gonna atleast take valve cover off to make sure I didn't miss anything then I'll go from there. But my motor and yours sound kind of similar. Also having this other little thing happen took for ride today about 100 miles then let sit idle and idle is a little bouncey will idle at 1000 like normal but then will spike up to about 2000 rpms then drop to about 750 and almost want to stall out then back to 1000rpms kind of weird goin to try to get a video of it while it's happening

    @TravAZ running forged motor from alpha and also their top mount setup using rosella 5w40 like Henry has suggested I did notice a little slack on the timing chain when I had the valve cover off the other day. Am I goin to have to do timing over if tensioner wasn't set correctly ?

    It goes away once I put a load on motor and doesn't happen again until I come to a stop and let it sit at idle for 20 -30 seconds.never happens when boosting. No check engine. I thought it was the 2 cracked spark plugs I had found but I guess not. @rabtech I'm having an occasional hesitation when accelerating have to reset then goes away.starting to think may be timing because of the sound. But I feel like also having symptoms of a bad throttle body because of the way it hesitates and puts on boost super Early. Sling will sputter and struggle to accelerate like if there was a bad plug or coil. But no codes.

    @varanog78 I wish it always wasn't like that this sounds been bothering me like crazy. But I'm still coming just trying to possibly fix this before i leave if not I'll be showing up with the first diesel sling around

    So not sure if this is piston slap or it is something else I've had this goin on for a while pretty much since i installed motor. And at first I was convinced it was piston slap since it only happened at idle. And goes away when on load or boost. But recently I've noticed it does it still even after the piston have warmed up but once again only at idle. It starting to bother me Especially at red lights maybe someone here can let me know.first video is start up second video is after gettin it warmed up and then letting sit. The sound doesn't start immediately after warming up it takes about 20 seconds sometimes longer sitting at idle and then it will start back up. Sound does go way once past 1300 Rpms and won't hear it from there on. Sorry about second video being so dark I was outside


    Sorry but glad some one said it @Maverick5990 I know a lot hard work go in to these mods but some mods really make me say why. It changes the whole front of the slingshot which is was attracted me to the sling .i still can't believe you guys are trying to reselll that death trap hey call a full enclosure dying to see one up in person and wish I could drive in one I just wanna hear how much all that plastic moves around when on some roughy roads. I see this bumper being heavily discounted down the road.

    so got code again but like after the first time it was about another 3-4000 miles and have video of how it drives.wont let me really go past 3000 rpms and feels like all boost want to kick in at that point. if you listen very well at the begggining of first video you can kinda here a cut with a like with like a little metal clunk my gauge isn't in video but it tells me afr is in the 9's when its happening
