Tea kettle whistle during cold months (suspect a manifold leak) how easy is it to find and tighten the bolts?

Hey y'all,

I have the "tea kettle" whistle appears to be temperature dependent making me think I have a leak on my manifold (intake or exhaust I'm not sure). A lot of posts I've seen suggest that simply ensuring the bolts are tight can be a solution (hopefully it's not a crack). However, when I try to figure out how to find and tighten the bolts, I find really in-depth videos that appear to require tools I don't have. I just have a set of metric and torx wrenches, and I am wondering if this is something I can do alone and avoid paying my mechanic his $70 an hour labor cost.

Does anyone have a good step-by-step guide?
 
The torque spec on the intake and exhaust manifold bolts 23- 24 ft lbs.
Most are easy to get to except a couple below and here is a torque sequence.

My plan is:

look at the thing, can I see a crack?

if no:

tighten the bolts.

If that doesn't work then I think it's safe to assume the manifold is cracked.

You might consider doing a smoke test on it to confirm. I found this video and am getting ready to do this myself to chase down a possible leak in my vacuum lines and/or intake manifold.
