ok i am installing a jdm b16 into a cx hatch, went to bolt the int. shaft to the block and noticed all but 1 hole was stripped, i cleaned the holes out a little better and their is NO thread left, i searched and found just 1 thread on this, and ill assume its not safe to only rock 1 bolt instead of 3, but what are my options? i need to get this engine in the car tomarrow, so whatever i do will have to be early in the morning...

heli-coil? never done it, is it safe, i dont need the int. shaft coming out and doing damage that ill be liable for...

tap- aluminum threads? is that safe?

any other options? i was thinking jb weld, but im going to have to be creative with that, any ideas??? i have every size honda factory bolt possible so if anyone knows of one i can tap the block for and it be SAFE for THE LIFETIME OF THE ENGINE, then itll be good, thanks for any input...

 

your probably going to have to tap that hole,no thread left, how'd that happen?

 

probably just tap it and then drill out whatever your putting on to the size of the bolt...

 

i dont really know, we got the engine with the int shaft on it already, i took it off a couple days back with an air wrench and never thought twice about the threads, i went to clean them out a little before putting the int shaft back on (we had cleaned the block some and their was some grime in the holes) and found the threads GONE...

 

used perma-coil (same as helicoil), worked great, just hoping it holds for good...

thanks guys, just pray this thing holds
