Lifter tick after chain replacement

I have a 89 240sx, and I had to replace my timing chain.

Now that it is all put back together, I have a serious lifter tick after the car warms up... What do you think this could be?

The timing is 15 btdc, and a manual inspection of the timing mark at tdc, and a feeler gauge shows the valves have some clearance.

I thought I may be off by 1 notch in the chain, so the lifters would float a bit, but the feeler guage disproved that (i think).

Any ideas?

off a notch.....had the same problem

apart from taking it all apart again, is there anyway to tell where it should be from looking at the cam/lifters only?

i was just a lazy fuck and took it to a shop. they said it was off. i suggest you do the same they did for next to nothing
