Ooooooh dr Loch.... I didn't want to be the one to tell you this.. but there are no 'details' when it comes to 23C's. SamN40, John UK and others can best describe how to deal with this engine, but the I&T manual- the one's people love to hate.. was all I had.. and by re-reading it, and later watching a CD kindly sent to me by Bill Brox, I 'think' I got it aligned as close as it will get...
Yeah it seems that you need navigation intruments from the sound of it... 90 degrees a starboard, 3 o'clock level.. belay all valves on #4... steady as she goes... oh man... but the teeth are big enough where you will know if it is right/close with the naked eye... I wouldn't lose sleep over the camshaft, if the bushings are cooked, boy do you have a machine shop project, if the bushings are good, just with the cam followers in the way without removing the oh btw.... I was told on here that a worn timing chain will make smoke, so like you, I tore the front end off, pulley was easy that time, and after all that... it made more smoke than the old chain... so.... I dunno what to say....
Where are you?

Quoting Removed, click Modern View to see

Tony, I certainly agree with everything you are saying. My tensioner is wore out and I believe the chain is stretched, I will know more about that once I get the new chain and do a comparison. What I was making reference to was the navigation instruments needed to get the cam installed and lined up correctly. I can see the scribe marks the person at the factory made, but, If the chain is stretched that will also throw off the injector timing since it's geared to the camshaft. Where I was going is to put an end to the all the navigation references when trying to install the cam and get it lined up correctly. The methodology that is explained in the manual is... lacking in detail.

What I've done is put my degree wheel on the crank so I can get the values needed to install the cam without all the navigation. With my old chain I know where the current intake centerline is with relationship to TDC. Don;t know if you can see, but I've removed the rockers so I don't have to worry about a valve contacting the piston while I try a few other things, I love experiments :? The dial indicator in on the end of the pushrod. I'll look at the results with the new chain to see how far they differ. Once thats done I'll spill time the injector pump against the degree wheel just to see where it is, already know where it should be. I'm curious of others things as well with regards to the cam events, not they really make much difference in the whole scheme of things, just curious. What I know now is that the intake centerline is close to that of a gasoline engine. Which is what one might expect. I Will know more once I get the new chain, I really don't want to repeat the steps if I can help it. Comparing the intake centerline with the old chain against that of a new chain properly set will give an idea of how far the injector pump timing would be retarded old versus new.
