Guess you have never owned a 86/87 Buick GN V6 turbo. Mine are 95% leak free BUT most for the average guys leaks bad !! Buick calls it undercoating
Pain to work on someones car an ya reach up from under an your arm is all crap. (would add extra $$$$ on their bill)
My CSX motor leaked the same place among others. Luckily now my SIL is fussier than I. He takes care of all my cars now.
