Review on OBDMONSTER Crankshaft Removal Install Engine by Robert Layne

Ok. This product really works. I used it to seal the crank of my 09 N54. I originally thought getting the gasket out wouldn't work because it didn't work the first time, but this kit came with screws. Just don't use them. Seriously, not a good idea. Get sturdier, similar screws like Home Depot. It works well with a variety of bolts and installing the new crank seal was easy. Worked great.
