Guest chrisrocc Posted December 28, 2014 Share Posted December 28, 2014 Hello, I searched the internet, and tried using other sources and cannot find anything on how to time a 248 straight eight motor. I didn't touch the timing chain or take it off I just want to make sure when I got the motor it was timed correctly I can see two notches on the gears but how do I know for sure the motor is in the right timing state.

JFranklin Posted December 28, 2014 Share Posted December 28, 2014 (edited) Maybe you need a reference book such as a MOTORS manual or one specifically for your car. It is hard to own and keep up a vintage vehicle without one. Check on Ebay or Abe books for one, or your Buick parts supplier.

MCHinson Posted December 28, 2014 Share Posted December 28, 2014 chrisrocc,Welcome to the AACA Discussion Forum. I have moved your question to the Buick Pre War forum. While I would suggest you purchase a factory service manual, I am sure someone here can help you with your question. Link to comment Share on other sites More sharing options...
pont35cpe Posted December 28, 2014 Share Posted December 28, 2014 With #1 @TDC timing marks on cam and crankshaft are both clocked at 3 oclock with 11 links between the two marks. Original timing chain has two copper washers to help get it right, each copper washer is aligned with each timing mark on the cam/crankshaft gears. After market chains may not have the copper washers. Hope this helps. Tom Link to comment Share on other sites More sharing options...
Mark Shaw Posted December 29, 2014 Share Posted December 29, 2014 My manual is in the trunk of the 38 now stored for the winter. I can take a look tomorrow if you still need the info. Did pont35cpe answer your question? Link to comment Share on other sites More sharing options...
37_Roadmaster_C Posted December 29, 2014 Share Posted December 29, 2014 (edited) Chrisrocc,The above info by Pont35cpe is exactly correct. Also, as mentioned above, a factory manual is manditory for working on these Buicks as they were engineered far beyond the current designs of the time and the manual addresses these fine points. Bobs Automobilia has reprints of the factory service manuals for a very fair price ***link to manual***. I have an origional factory manual AND a Bobs reprint, that way I can get the pages of the reprint dirty when working on the car and keep the origional 37 printed manual clean for bedside reading .RobinPS: the manual from Bobs is an EXACT copy of my factory origional.

Guest chrisrocc Posted December 29, 2014 Share Posted December 29, 2014 Mark Shaw, He did answer my question yes, but can you still look because I want to see how the manual says to do it also(not saying he is wrong just want to see).Thanks Link to comment Share on other sites More sharing options...
