    Stretch Bolts

    Does anybody know what the specs/guidelines are for reusing the stretch bolts on the 4 TEC motor. You have the head bolts, rocker arm bolts, con rod bolts and I think the base pan bolts are also stretch?

    There stretch to yield on head and rod bolts throw them in garbage, take the use rod bolts and throw them out the window while going over a bridge at 100 mph. There is enough problems with members motors lately, never reuse rod bolts. Rockers can be reused but its just not worth the thirty bucks in savings. Base pan bolts and mains are reusable and there not stretch to yield

    The only bolts I would reuse are the pto cover, oil pump, base pan, valve cover and acessory bolts.
