Hello. I refer the problem to my colleagues because I do not want to make a costly mistake a second time. I mean the so-called timing procedure on a chrysler 300m with a 2.7 V6 engine. I heard somewhere on the internet that there is a special procedure for this. I am not talking about the alignment points of the shaft and camshafts, because that is what I know. I am talking mainly about this timing chain tensioner that is stretched by oil pressure. I do not know whether it should be mounted "closed" and wait until it is filled with oil, or mounted open. The so-called timing lock to prevent damage to the timing. I do not know if this is to secure the chain when removing the tensioner, so that it does not jump, or if it also has other uses. Please help.
