Smile Replacing timing chain tomorrow!!

Posted last week about getting my timing chain replaced at 125,000 miles. Well, I'm scheduled to get it replaced tomorrow. I wanna take time out to thank you all for your advice. I have to drive 90 miles to get it changed. Hopefully, I will make it there ok. I will post when I get back tomorrow. By the way, what changes can I expect to see in performance etc?. Is this just a preventive maintenance fix?. Will my mpg. increase? If it wasn't for this website I probably would have kept driving this machine without not even knowing the damage I was doing.The previous owner really took great care of this car the last 22 years, but he somehow omitted the timing chain. I went through the service records that he gave me and here is just some of the items that he replaced:
replaced injectors @ 116,00 miles
new water pump @100k,
new michelin tires @ 114,000k
replaced all drive belts @ 100k
R134 conversion @ 106k
new motor mounts@ 100k
Every oil change was documented for the entire 20 plus years. The owner had 4 benzes and a 3 car garage so he sold the "oldest" benz.
Thanks in advance.

The previous owner probably didn't want to spend the money to replace the timing chain. You probably won't see a discernable difference in performance or gas mileage, but you won't have to worry about the engine self-destructing because the old timing chain failed. Hopefully you're having new upper and lower timing chain guides installed too.

And the tensioner, don't forget to replace the tensioner.

the diff you will feel is a more responsive engine off the line.a stretched chain means retarded valve timing which translates to an engine that doesn't feel powerful until you reach 2500-3000 rpms.

When I replaced mine, I did not replace the cam sprockets. I wish I had, not so much for reliability but because I could not get the timing where I wanted.
