Ok first things first...If the chain isnt relatively tight then you have an issue right off the bat. The lower chain that goes from the crank to the center cam gear should be tight enough to not to "Jump" timming. If your worried about oil pressure to start off with prime the pump(look up priming oil pumps KA24de). What your seeing I think in the jumping of timming is natural. In other words One complete revolution of the motor on the stand the chain marks WILL NOT LINE UP. This is normal and its not jumping timing. It is because of the amount of teeth and Gears. I went through this my first time too. Now quite a few KA motor builds under my belt including my beast of a KA-t(see signature) I can agree with Rogo completely. And yes it still weirds me out but I now know its normal. I know it seems weird that they dont line up again but all is good. They will if you spin the motor a few hundered times. And they dont jump timming. Just an illusion. AT TDC you should still see the cam and crank gear marks the same but not the chain marks. Make sure you look at the lobes of the cams they should be almost pointing to the right and left sides of the motor for piston 1. Ill try to post a pic. The only thing if you feel your chain is too loose then your chain tensioner is missing its spring this should firmly press against the chain , Or your chain is stretched or the wrong one. Hope this helps and shoot me an IM if you need further help on here or KA-t.org or TexasNissans.com I am the same on all of them.
Peace
Rick
