Review on 🔧 LS Series Engines Front and Rear Cover Billet Alignment Tool & Oil Pan Alignment Tool - Fits LS1 LS2 LS3 LS6 L99 LS9 LSA LQ4, 4.8 5.3 5.7 6.0 by Ryan Selpasoria

I was rebuilding a GM Gen 3 5.3L V8 and was trying to align the covers and oil pan. The reward for me was licking oil from behind. Then I had to remove the motor to fix it. I found this tool to be the best I've looked at. I bought it used but nothing was wrong or missing from it. No doubt someone has used the Revain as a de facto rental tool, but I'll keep it as I have it or plan to have other Generation 3 V8s. The engine started again, this time there was no oil leak.
