he would NOT notice any decrease in performance anyway due to the very slow wear process over time.
and they dont have to launch hard.
any time your putting more then usual stress on the chain WEAR HAPPENS!
and it takes nothing. i'd put stress on my bike when i was 10years old riding a bike.
NOTHING is 100%
wear happens over time

and once again congrats for you and ANYONE else that never replaced their timing chain
we all care so much

 

My dad's van has a loose timing chain right now, and man, that's some serious stuff. It'll be running fine, then you'll try and accelerate, and it'll bog, so then you hit the gas more, and it'll bog more. Pretty soon, your flooring it going about 20 in a 70. But, if you shut it off for about 10-15 minutes, it usually corrects itself for a while. Weird, but I wouldn't want to risk that happening to me.

Wear on your bicycle? Rofl right now, seriously, we are talking about a timing chain, not some bicycle chain on a 20 inch bike. Yes, wear and tear happens, but this is a mustang with a bit over 100k, your comparison doesn't make sense. If the car was raced or mashed for over 100k, I would say replace it if it's running like sh**, but he is implying that (the owner of the car) just because it has over 100k that he should replace it. The answer is, NO!

 

damm so i guess you konw the life history on the car
i garuntee there wear on the chain and sprockets

 

OMG who is saying there isnt wear? i think you have made it CLEAR that "WEAR HAPPENS" but unless you treat your engine like **** you are fine. This is pretty much whats going on. I just bought new tires for my truck and they have wear on them....... and.... THEY STILL WORK GREAT!

I have highlighted the above area, no sense in repeating myself!

 

It's a double roller chain. It's fine. My 98 has 262,000 miles on the original chain, and has no slack. If you want to check yours, remove the cam sensor. It's just two small screws. Get a ratchet on the crankshaft and turn it clockwise. When you do this you need to be watching down inside the housing where you just removed the sensor. If your trigger wheel turns as soon as you move the crankshaft, the chain is tight.

 

are you sure stock 3.8s have a double roller chain?
i thought it was only 1
if its a double rolling chain on a stock or even bolt on v6 then its not even worth touching that almost at all

 

i'm 100% positive it's a double roller. those dudes are awesome.
