View Full Version : KA24DE Timing Chain Questions

10-15-2021, 04:53 PM
It's been a long time since I've been on here, but I'm doing a KA swap into a 1970 Datsun Roadster and I need some wisdom.

I'm replacing the head gasket on a KA24DE and I might have put myself in a pickle. I set the engine to TDC and I marked the upper chain with the dimples in the 2 cam sprockets before taking them off. However, I failed to mark anything on the lower chain before taking it off the idler sprocket.

My question is, am I screwed and need to take off the front cover and line everything up with the silver chain links and dimples or do I just need to make sure the idle sprocket dimple is in the position shown in the attached pictures?

Thanks so much in advance,

Ive seen many not mark the bottom chain just make sure it doesn?t come lose but I wasn?t comfortable with that so I just took off the whole cover just to be sure I would hate to tell myself I told you so
