: N* Camshaft Removal: Special Tools Required?

So I took my STS to another local guy today who listened to it and confirmed that there is probably a lifter problem somewhere around cylinder #5. Says he's willing to do the job but it requires a special tool to hold the timing chain sprockets while the cams are out to avoid losing timing. I have read through the FSM camshaft removal section and can't find any refernce to a special tool. So my questions are:

1) Is a special tool necssary?
2) Where can I get a camshaft and lifters?
3) Should I do both banks or just the one making noise?

TIA

STS 03 already answered #1 in my other thread in Seville land: J 38822. So my revised questions:

1) Where can I get J 38822?
2) Where can I get a camshaft and lifters?
3) Should I do both banks or just the one making noise?

Thanks AJ. Appreciate all the help I can get here. Would also be interested in opinions on my current options I am weighing:

1) Replace offending lifters and likely the cam to make the noise go away. Dump the car before the inevitability of headgaskets, the other bank of lifters/cams and/or suspension bites me in the a$$. Car uses no coolant, but I do not know previous service intervals before 87,000 miles. Currently 101,000 miles and I have changed it once.

2) Yank motor and replace with GM reman long block.

Going to figure the price differential and decide from there. If I can do the long block swap w/in $2K of the cam job I'm thinking that's the way to go.

Suggest you call SPX directly for J38822 - I think I have seen it for around a little more than $100. I assume that is the tool that hold the chains in place when you remove the cams.

Thanks Logan - that's the culprit. Beginning to find out its part of a bigger set J-41619 which has more stuff. As usual, do enough Googling on Cadillac and you end up back here:
