I did a search but have a hard time getting that to work. I hate to start a new thread every time I have a question but thats all I have been able to use. So I give up, what is the trick to timing marks on Y Block Dampners? Are they all the same or different depending on dampner. I marked mine before I removed it, but I broke it cleaning the threads with a bolt. I went to tight and heard it snap and some penetrating oil ozzed out on the back side. Got that sick feeling. So, I have extras but, no timing mark. The old one was almost in line with the key slot on the crankshaft, but again, only mark is the one I made in line with the indicator before I removed it. The donar is identical, including no apparent timing marks.
