I'm new here, for starters I bought this car under the impression the head gasket was gone, but upon tear down I literally grabbed the stud and pulled it straight out by hand. I'm not new to the game however helicoil vs timesert is a big decision. I've read terrible things about helicoils failing. Then timesert wants 445 dollars for the 4160 kit I need. That's just not a option for me. Basically any input on helicoils not failing would be reassuring I guess or perhaps someone has the timesert kit they've used and would sell me cheap.
