Exclamation Intake Cam Slipped help?

Hi, I have a 2006 SS/SC and was just finishing changing the timing chain.
I put the timing chain cover back on, and put my 15/16ths wrench on my intake cam to give the engine a full rotation to make sure everything was fine.

It did I believe 1 stroke fine, but I clearly didn't tighten up the 18mm bolt enough, and the camshaft began rotating independently of the timing sprocket, hence not rotating the exhaust camshaft with it. Now everything feels bound up lol.

This is beyond my automotive knowledge at this point, so I decided to do the smart thing and drop it and leave it alone haha. I haven't messed around with the camshafts before and I can't afford to **** this up lol.

What on earth do I do to get everything back where it needs to be?

Thanks a ton!

The engine should only be rotated by the crankshaft sprocket (drive gear) and not the camshaft sprockets (driven gears). The camshafts are keyed to the cams; therefore, if you're able to turn the bolt and the cam doesn't move, you've either sheared the bolt off of you've damaged the sprocket to cam keyway.

Ya I second Sport Red.

You want to mind where the chain gets tight when you rotate it over. So if you turn the crankshaft, it pulls the chain tight along the non-moving chain guide up to the Intake camshaft, then that tightens up the chain between the intake and exhaust cam gears...that leaves all the slack between the exh gear and the crank gear which is where it should be, your tensioner will take up this slack when engine is running.

You should punish yourself by making yourself redo the installation. At least at this point, you have a handle on what needs to be done but this time rotate the crankshaft. Also, count the chain links between the cam gear dots when you initially set it up...after your rotate the engine twice around, verify you have the same amount of chain links between the dots. You need to do this because the chain link colors won't line up on the dots again until 374 rotations of the engine. (I made up the 374, but it is an unreasonable number regardless).

"I made up the 374, but it is an unreasonable number regardless". Lmao! Love it! I busted out laughing at work. True story though. You would be amazed how many people will argue with you and try to say it will line up every other revolution.
