Works like a dream!
I only used the one to align the rear main seal on a 5.3 GM motor. I replaced the seal the first time thinking it would center itself, but it didn't. it leaked worse than before. Second time, I used this to align the plate to crank. then I used the jig it self to press the seal into place.. I tell you, it worked like a dream. no leaks no nothing. I would recommend installing your rear plate loose first, then install the lower 2 pan bolts and tighten them to pull the plate down to the oil pan in small increments. insert the jig till it fits loosely and evenly all the way around. it should rotate freely when the plate is aligned properly. Tighten the rear cover bolts to 18 ft/lbs in sequence and lastly the lower 2 bolts from the oil pan to 106 in/lbs. Tighten the bottom 2 last, because if you tighten the bottom ones first your seal is going to leak like crazy. lastly apply a little grease to your seal and use the alignment jig to push in the seal.I am happy to add these to my collection of tools..

Works but. Not 100%
The tools are nice. I have been build ls engines for years and wanted to try a metal set like these. I have the plastic ones and they are starting to show the use. These are a lot nicer when driving the seals in. I love the metal, very firm. But the oil pan jig works on the front of the engine only, need one that works on rear.
