Changing the Timing Chain Questions

[Polish12]

Hi, I found this site looking up info on changing the timing chain... I have a 1995 318ti which is stock... I'm down to the lower timing chain cover and to take this off I it says I have to set my timing and it said I needed some special tools, do I really need these tools or can I proxy something for it? If not where can I order these tools? What are somethings i might want to know while changing it. Thanks for reading!

Is there a reason why you are changing your timing chain?

Well I was driving home from a friends house i started to hear a bit of knocking and it kept getting worse by the time i got to my house it got pretty bad. I opened her up to see if there was scratching anywhere and the only place a found some was just a little bit and it was on the plastic piece that goes around the top of the timing chain and the chain wiggled a bit and I figured it was over do for a new one anyway...

The timing chain is usually never replaced, the tensioner is what typically needs to be replaced.

The chain really wouldn't make a knocking sound. Knocking is usually from rod/main bearing problems, or pistons.
