Well I do feel kinda stupid for not asking this earlier, but its better late than never.
When installing a new tining chain tensioner on a 616912 , 83 240d I did not loosen the bolt that applies the spring pressure. I just primed the tensioner with oil and installed.
I'm hoping this is O-K. I've been driving it that way for about a year.I read some posts about this recently and realized I may have done the job incorrectly.
Is it possible that I have too much tension on my chain right now. Could it wear out the tensioning rail prematurely? I'm affraid of cauing catastrophic failure. That would be devastating. My engine has great compression and I want to keep it that way. thanks for the help and for not making me feel even more stupid.
