hes kinda right but this doesnt necessarily make him less shady.....the one year ago thang raises doubts
Some solvent based cleaners can be a tad hard on seals, but if it was only 5 minutes and a bunch of crap came out, I say you have more issues than seals. I say quit worrying about the mech and if you don't trust him, don't go there.
As for your issues (and I ain't talking about lack of caps and punct-u-ation): I would run a double dose of Auto-Rx and choose a good oil....replace the seals if need be, after that.
