I had a timing belt service where the mechanic broke the plugs taking them out (common) and replaced them holed but sealed and retained by resin. I only found out 14k miles later at different garage doing gaskets, found gunk in pulley = new pulley. Is resin an accepted way of holding plugs on this variable valve drive pulley. I guess the resin cost more than the plugs?

need more info to assist.what was the 2nd mech opinion on the resin repair?
2nd Mechanic had never seen such poor workmanship. Also took the part to Audi dealership - confirmed it was not a recommended manufacturer service. Both recommended replacement pulley wheel. Resin did not get good bond onto pulley wheel because of dirt and oil. I could send you a photo. Trying to find anyone who commonly do this when the plugs are so cheap and in stock most good parts dealers.
