Review on 1215 M12 🔧 x 1.5 Metric TIME-SERT Kit by Phillip Brown

Bought this kit to replace block head bolt threads in VW Rabbit 81 diesel block. They were installed almost 2 years ago and are holding up. Unknown to me, until the seal blew, the previous owner replaced the threads with helical threads. Needless to say, the coiled coils failed and blew out the filaments in the block, making coil swapping impossible. The timesert bit was slightly larger than the spiral hole, making it fairly easy to clean out the tight threads after removing the old coils. Installation is easy if you follow the included installation instructions with attention to detail. You want to make sure you drill the holes GOOD AND STRAIGHT. Of course, if the holes are slightly offset, the screw heads will not fit properly in the holes.
