Is it common for the KA24E's to crack their exhaust manifolds? I dont know for sure, but i think mine may be cracked, a light clicking sound thats around thru the entire rev range.

On the other hand, it may be a bad lifter, but it sounds more like an exhaust leak as its definitely more noticeable on hard acceleration, or when revving the engine.

Mine does the exact same thing. It always has since i bought it with 167k miles on it. I've heard the lifter clicking a few times and it's a different sound than the manifold.

I tightened up the bolt on the manifold and it got quieter but i still hear it.

Whaaaat? Um, maybe you need to brush up on your nissan engine knowledge, the KA24DE uses shims to adjust the valves, the KA24E uses hydraulic lifters just as the SR20DE does. Both engines make that clatter on startup because of that.

Now maybe your thinking of the Z24i which is indeed a solid lifter/adjustable setup.

Not trying to sound like a jerk at all, this is more so you can avoid looking like a doof in front of a mechanic or what not lol =)
