Sup everyone... I bought this GSR block for $350 with everything except for rods and pistons... but, it has crack on one of the engine mount mounting threads and the rest has no thread (lose thread)... please view pictures below and kindly give me your opinion if this is fixable/usable. Welders what do you guys think? TIA




If its fixable... do you guys think its fine to boost it 20psi? I'm getting it sleeved and bore out to 84mm. Thanks

 

looks like its been striped out then fixed with helicoils weld it up, fix the threads a little better, and boost the **** out of it

So it is fixable right? You think I'll have any problems with it in the future?? Thanks!

 

ya i think you can fix it with helicoils, i just got done doing something similar on a dirt bike i have.

 

weld the crack up and tap the holes for a larger thread dont mess around with helicolis

how do helicoils work?

 

they are steel threads that you insert into hole that the threads were damaged on. first you tap the threads oversized, then you put in the helicoil, then all is well. dont think that this is a bad thing, as it isnt. if you look closely you can see that Honda tranny's come with helicoils already installed in all mount bolt holes.

 

best thing to do is fill the holes and then retap or try TIMESERT Better than helicoil in my opinion.

 

Thanks for all the reply guys

 

Use JB weld lol

 

Man thats wierd. The same thing happen to my old ls motor in my 97 coupe. I rethreaded the holes with a tap and die set the next bigger size and course thread instead of the fine thread. Never had a problem after that, even spraying a 100 shot.
