Weird problem?.. D21

Ok so my engine has a rattle to it even after doing the lifters. Seems to be lacking power as well.
Some times it will stop its rattle and gain power.....
Worn lifters? Or worn push rods?
I was thinking that it could be a worn point on the push rod head and when it spins/rattles around to another point it might take up the space and stop the rattle, which in turn could make the valves open the right distance and gain power.
What are my options as I have a trip coming up that I want the 4wd sorted for.

Cam lobes? A lot of older Nissans had issues with shite quality cams....

Presuming you got td27? Rocker shafts can wear. Need to remove rocker assembly and check the underside (load side) for wear. (sometimes sliding rockers down shaft is enough to check)

As far as I know (which isn't very), chuck it out and put a new one in (if that is the issue)

Sweet I was just thinking if you got one repaired it shouldn't do it again?.....
