You can use a Heli-coil or time-sert. Both of these are threaded inserts that replace the stripped threads in the head. The steps involved is to drill the hole slightly larger, tap the threads for the heli-coil/time-sert, insert the heli-coil/time-sert and the put in your bolt. Have four on one on my ti's and not an issue at all. __________________ 01 740iS Cosmos Black 97 318ti Boston Green 99 318ti Titanium Silver 13 X5 3.5XDrive Cosmos Black 97 318ti Alpine White (gone but not forgotten) 88 325iC Schwartz Black (sold) 97 740iL Schwartz Black (sold) 84 633csi Schwartz Black (sold) 96 318ti Alaska Blue (sold) 08 X5 4.8i Titanium Silver (sold) |
