PIstons and timing and TDC, oh my!
Posted by Erik Karlsson [Email] (more from Erik Karlsson) on Sun, 26 Nov 2017 16:06:09
Am putting together a V4 that came to me with the distributor removed. I'm trying to identify the best way to be sure that when the timing mark is aligned on the front of the engine, that I'm not pointing to the TDC of cylinder 4 vs. cylinder 1. Are cylinder 1 and 4 in lockstep with their power and exhaust stroke, or is there a difference so that when I'm at TDC for 1, cylinder 4 is at a different part of the stroke?
Or does it really matter? If I have the timing mark aligned and I put the distributor back in so that the dizzy aligns with the mark on the distributor...then put the wires back to the right spots on the distributor...I'm thinking that it should be okay (but that assumes that 1&4 and 2&3 travel in lockstep with each other...both at the top and bottom at the same time)...
Anyway - looking for suggestions. :)
