Took my 440 out to replace rear main seal. Noticed my chain is sagging. Great…

Thats about normal.

Normal as in it doesn’t need to be replaced?
Haha, no you should replace it. Double roller.

I've seen worse with that type of chain.....

I’m not sure, bought 440 from a guy who Didn’t know much about anything last year.
Kind of a no brainer than. Replace it and degree it.

Yea I agree
Ya, that's pretty normal for anything with more than a few thousand miles. Since you're in there, put a new quality double roller set in. I'd degree it just to make sure you know what you've got.

I'd check what the cam is set at now then go from there. If it felt a bit on the sluggish side but was tuned well.....you might think about advancing it a couple of degrees or so. A cam that's advanced a bit brings in the torque at a lower rpm but you also need to make sure you have good valve to piston clearance. If it was running good before....leave it timed in the same spot but you will need to determine what that spot 'was' 
Not that hard to do though.

Measure your cam to crank center distance. If it's undersize from line honing like mine, you'll
need a -0.005 or -0.010 under setup. I just bought the last cloyes double roller in the world
from Jeg's. I bought & put a new stock one on and had to buy a -0.005 under set. FSM says
3/16" is max.
Good luck finding a single bolt set!

Yeah, 3/16 of rotation of the cam gear.... Measured at the outer edge of the cam sprocket... I'll bet if you measure that it'll be less than half the allowable slop.... Not saying I agree, just stating what the factory service manual says..... Which is always the point to source for accurate information...

So I am an idiot, I changed the single to a double, put it all back together and then realized i forgot this thing. What is it and do I need to take it all back apart?
That is an oil slinger, It's supposed to reduce the likelihood of oil leaking from the from seal & it's supposed to improve lubrication of the timing chain... Not all engines had it originally so some folks intentionally delete it & others are religious about it needing to be in place...

Oil slinger that helps keep oil from going out the front crank seal. That’s an important part.
Yep and yep. It is but can be left out without issues.Oil slinger that helps keep oil from going out the front crank seal. That’s an important part.
