any body ever tapped the motor mount bolt holes in the block of a b18 vtec?

 

I just Helicoiled one of the bolts that hold the halfshaft to the block...it worked great!!!...I toqued right to spec with no problem....I personally have never done an engine mount but I have heard of people doing them with success....by the way I ordered the helicoil kit from the local Napa store for around $60...good luck!
