Anyone had to repair the threads in the FCAB bolt pockets? I had to tap the threads of both front bolts and after doing so there must not be enough material left to get the bolt up to the torque. Anyone see any issues with using a time sert in this location?

Based on this writeup a timesert will not work since the threads are already basically an insert welded to the frame.Originally posted by F1Dryvr View Post

Sorry. A helicoil needs less "meat" than a timesert. Might be worth a try.Originally posted by F1Dryvr View Post
But the correct repair would be cutting the floor pan above the FCAB exposing the welded insert, cutting the weld off the insert, find new insert and weld it on.

I cross threaded one of mine and hired a shop to re-tap it for me since I didn't have the guts to do so. I've heard that a stud can be welded in place if your threads are too far gone.'06 BMW M3 6MT Coupe - TiAg/Imola

You can do it. I've done it twice (on the same threads). First time used timesert, second time had to use bigsert. With bigsert there probably isn't much material left but it torqued up properly. Use timesert (search for the longer ones than come in a pack) and it should work out. I will probably one day look into the options that eacmen posted.Last edited by e46mpwrd; 10-20-2020, 12:03 PM.'06 IB/BLK 6SPD PN66072Comment

Bigsert is 500$?Comment

Thank God. It’s good to know that it’s at least possible to try. So are you saying that a regular time sir won’t work? And did you have to use the time CERT and then realize it didn’t work and then have to go to the Big Cert?Originally posted by e46mpwrd View Post

No, sorry for being confusing. I screwed up again and cross threaded the timesert, so bigsert was needed. Moral of my story is don't rush a FCAB job. Timesert is what you need but you should look for longer timeserts (the one in the pack is like 1cm). Something around 2-3cm will be better. They offer them just google around.Originally posted by F1Dryvr View Post'06 IB/BLK 6SPD PN66072Comment

They have a pretty informative website, and I think almost all (maybe all) of their products are on Amazon too. I love Timeserts, they've bailed me out before.'03.5 M3 SMG Coupe - Jet Black / BlackComment

I've time-serted one before without issues. It was years ago, memory is a little fuzzy, I vaguely remember the lip being a little tricky to work around but other than that no problem. That car saw a ton of track time too.IG: @limited.slip

Timesert tooling makes it really simple to do correctly. I had to use them on the VANOS head bolts before. Worked great!
