I removed the bushing which are brass from the block, it seems that the treads in the block are bad, I have 1/4 national-standard pipe tap to use, the engine is a raw water cooled 5.7 mercruiser year in 1995, I just want get the brass plugs back in, can a heli coil be used if these treads are too far gone?
