I have recently removed my valve covers to replace the gaskets and figured why not make sure all my cam caps are torqued to spec. Not thinking ahead I undid all the bolts and tried to re tighten them and low and behold they're been breaking issues, especially on the end caps. I'm not sure what I'm doing wrong here. Do I need to simply replace all the bolts to get them to be able to torque correctly? Is the Haynes manual method for torque accurate? Am I just way in over my head?
