318ti.org forum - View Single Post - M42: Accidently removed Timing Chain Tensioner!

TestaRossa · 06-18-2008, 04:17 AM

I replaced my tensioner yesterday and I think threw the timing.

I did not decompress the tensioner before installing it. After I got it in, I started it up and heard the chain noise for a few seconds and it went away. Then it started to idle really rough and lopey... So I'm assuming it jumped a tooth or two.

Now what do I do... How do you reset the timing? Do I need to take the chain off to do it?

I can't find instructions anywhere on how to set the timing from begining to end (ie; what needs to be removed to get at it and how to reset timing)

Can anyone tell me how I can do this or confirm that this is even the problem?

I haven't yet taken the valve cover off yet to look at anything.
