ok like the title says. yesterday afternoon i began puttin together my ls vtec, i bought a B18B1 from a guy on craigslist and asked him that if anything is wrong with the block to lmk right then n there so i could address the problem before i started work on it, even after i gave him the money and had the motor in my car ready to leave. he said not its in perfect condition. anyways when i took it apart everything was great almost no signs of wear or anythin on any of the bearings, so i was thinkin koo he did tell the truth, but i spoke too soon. after everythin was put together i started to bolt down the head and come to find out there is 1 stripped head bolt, or much rather where the bolt connects to one the block. freakin liar im thinkin to my self. well my question is this, is it possible for a machine shop to fix this problem without me having to remove the head? because this would save me so much time and money. or do i have to take it apart. if ur local to norther cali (sac area) wat are some good machine shops around here. thanks

 

Head has to come back off, no way around it. Your gonna have to tap that hole with the head off and get a new bolt

 

i was kinda figurin that. any idea how much a shop would charge for that? ive never takin a motor to a machine shop b4

 

so its stripped in the block?

drill it out and put in a helicoil...no need for a machine shop

 

yea i thought it was the bolt so i removed one of the other bolts from the head and put it in, and it did the same thing so its stripped in the head. ive never done helicoil how does that work? thanks for help

you go and buy a heli coil kit with the size you need, drill out the old threads push the spring into the hole and viola new threads....the direction will come with the kit.

if they are good enough for 40 million dollar aircraft they will work on your car

 

Same thing happened to a dude at my work with his b16. He helicoiled it. Three years later it's still fine.

 

there was a really nice write up on this. i'll look around.

My friend is running a b18a ls/vtec right now with some OS P30's in it, b16 head. Has 2 helicoils in the block for the head bolts. Holds up fine.

 

where do i get the helicoils from? i kno my job doesnt carry them, i work at an autoparts store.

 

Ace/True Value probably Menards/Home Depot/Lowes

I've only seen em at my local hardware stores, but I've never looked at the big guys, I'd assume they have em as well, just wouldn't know where to look.

 

also me and my buddy were tapping the head to insert a knock sensor and his tap broke so we went to sears, home depot, lowes, ace, OSH and another locar store and couldnt find a freakin tap. the size is 12mm x 1.25 does anyone know where i can find the tap? all the sizes went from 12mm to 12mm x 1.5 to 12mm x 1.75 its like they completely skip the size. any idea? thanks

 

Haha, I know exactly what you're talking about. If you absolutely need it, its available in the small metric tap set from Craftsman, otherwise just look for it online and wait for shipping.

 

aint it a pain in the but not finding wat u need unless buying the full package. i guess im huntin for this thing again tomorrow. thanks for all the advice and guys.

 

We needed the same tap for my friends crank. We went everywhere. I could not even find it in a kit. So i just but the tap from a big tool supplier. Cant think of the name right now. But i pick it up for $9.

Sears has them, if they dont have it on hand they will order it for you...but i get mine from the Snap-On/Matco/Mac/Cornwell trucks....depending who shows up when i need some

 

Timeserts work really well also.
