head bolt stripped with the head torqued down...WTF!!!

[a1320honda]

So i got my car put together 2 days ago and drove it yesterday and today and slowly started smoking and getting worse to the point it went through a quart of oil today. So WTF!!! I i went to pull the head and 2 of the head bolt were stripped out to the point of where i loosed them by hand and then i couldnt get em out cause there was so much metal in the hole. I torqued the head down in 2 steps, 22ftlbs and then 62ftlbs. And they all tightened down pretty well. And just until i got the feel for it again i backed the timing off to decrease cylnder pressures. So what the hell, lol. And the 2 hole are fucked beyond belief. We tried timeserts and helicoils and neither would feel right just threading the new head bolts in. So basicaly the block is a waste after letting 2 engine shops look at it. So....anyone got an LS bottom end they wanna donate to a good cause, lol.

damn, don't know what to tell ya. Did you chase the threads with a tap first?

[a1320honda]

No, i never have before. They all felt really good and solid when i torqued em down. nothing felt like it bound up. I dont know. I just gotta get another LS block or bottom end goin before next friday.

Wow, I figured you were talking about the cam covers because those bolts are pussy, but a head stud? That doesn't even make sense. 62 ft lbs isn't that much for those bolts, hmmm.

did u reused the stock head studs?

[yay]

hey steve maybe some kind of liquid (oil or something) was in the holes when you torqued the studs in...coulda caused hydrolock...shit happends a lot with studs if they arent cleaned....

[Trannyman]

basicly its gonna need some helicoil action there. That sucks

I was told its too far gone for even helicoils or timeserts. Basicaly its junk....well, without spending more than what the whole motor is even worth.

[GetawayInMoscow]

Throw the block away, sell the crank to some all motor guy on H-T, rods too probably.

[yay]

you could go to a bigger helicoil and run a small block stud...haha then you can say that your motor is held together by chevy!! haha

[sefus]

know of an ls block but its not ready to be donated till the new engine is in the car and running... keep it in mind though.

[MrVtec11]

hey steve im waiting on you....come get em...

[a1320honda]

LOL, Josh told me what he really did to his LS. and wow. Like running seafoam and greased lightning crap for like 2 days.


I think i might have come up with a solution....and it involves accord head bolts.

[a1320honda]

So i figured out that with a little work....the accord single cam head bolts will work in an LS block when the hole is retapped to a M12x1.5. So the car is back together and the head torqued down to 62ft/lbs very comfortably. So now i gotta pick up where i left off with tuning and being set-back 2 weeks now. But its running.

nice job of improvising!
