Exclamation 4.6 sohc timing chain kit replacement ? Special tools?

I have a 01 bullitt mustang with 87k I think either a tensioner or a guide is either wore out or broke. A mild ticking sounds is coming from the front . I found a kit that includes cam gears crank gears chains , guides the whole 9 yards etc .. I've never changed a 4.6 sohc timing chain and the book isn't very clear. So here is a few questions that I would appreciate any info on !!

1. Does the camshaft on each side need to be locked or does it even need to be locked ?
2. Where can I find a camshaft positioning tool or is there way ?
3. Any tips to make the job easier?
Thanks

OK i just changed all the timing stuff on my bullitt. I bought the cam tools from summit. They however dont fit my aftermarket comp cams. I bought the otc brand that comes with the v8/v10 stuff and even works dohc. Make sure its in tdc on #1 before you remove the timing cover there is a mark on the timing cover as well as on the balancer. The tensioners are easy to mess with just compress and put a paperclip in them. The new chains should have two different colored links in them on goes on the keyway on the crank. That should help get you started any other question just ask.

Ok I think I can get it on top dead center . Buy I just went To summit but this tool doesn't look like anything in the book OTC Tools 6498 - OTC Ford 4.6L 4-Valve Cam Tool Kits - Overview - SummitRacing.com .. I I'm not wanting to change cams just the cam gears .. Does this kit actuallylock the cams in place or just position new ones ?? And does the cams HAVE to be locked in place or when I take the cam gears off will the valve spring compression turn the cam ? Thanks 01blackbullitt

That tool is for the 4v. The tool for the 2v is otc 7928.

No the tool does not lock the cams in place. It is used to remove the followers.

No you dont have to lock the cams in place but you will need to remove the followers if you do not lock them in place. If you dont remove the followers when you remove the chains the tension from the springs will spin the cam around just like you said.....Which is why you DO NOT want to put the engine at tdc unless you want bent valves....You want to put it in safe mode that way all the pistons are below tdc.
