what do you mean sloppy? are your struts blown? i would check struts. mine blew and it felt like the back end was hopping up and down real fast and gave it a jello-y/spongy bounce around feel. maybe your car feel like that too, i dunno? as for the h22. you have to drill a hole in the block so oil can get to the spool valve. i hear its a pain in the ass and it costs alot to get it running correctly and reliably. i would just buy a complete h22 and put it in.
