Als720 Posted November 19, 2018 Report Share Posted November 19, 2018 I have the z24 engine im doing a headgasket repair on today When i was torquing down the valve rocker shaft assembly one of the two middle bolts on the middle stripped it only got to 10 ft lbs of torque. What would my options be to fix it? Or can i run it like that?? Quote Link to comment
]2eDeYe Posted November 19, 2018 Report Share Posted November 19, 2018 Welcome aboard. Easy fix for stripped aluminum is a helicoil thread repair kit. Quote Link to comment
datzenmike Posted November 19, 2018 Report Share Posted November 19, 2018 Ahhhh aluminum and small bolts a lethal combo. 10 pounds is probably the upper limit. Borrow a good torque wrench or re-calibrate that one Quote Link to comment
Crashtd420 Posted November 19, 2018 Report Share Posted November 19, 2018 (edited) Helicoils are ok, depending on how much wall thickness you have . ... If you have the room to drill it bigger i would use a keensert.... They are similar but they are alot more perment, but depending on where and what kind of wall thickness you have helicoil may be your only option..... Pic is just an example....

Als720 Posted November 20, 2018 Author Report Share Posted November 20, 2018 Since i need to move the truck from were its parked i threw it back together the bolt is somewhat tight but wont be happy with it until i go to recheck the headbolts and see how it holds.. another question the parts store guy gave me the ngk iridium bpr5eix plugs for both exhaust and intake sides will does work the same as the bpr6es on the intake and bpr5es on exhaust?? Doesnt make sence to me, dont trust the parts store on this the guy was surprised to hear it had 8 spark plugs i payed $60 dollars for them so if they dont run the same ill take them back and ask for the right ones Quote Link to comment
datzenmike Posted November 20, 2018 Report Share Posted November 20, 2018 I wouldn't use iridium plugs. They may be OK in a 2000s car but NGK BPRE6 intake and NGK BPRE5 exhaust is whats called for by the FSM. This truck was 8 years old when counter guy was born. Up-selling bastards.
