Aluminum head steel bushings at header screws

[Rick Parker]

Is this a Helicoil that has come out (?) or a legitimate threaded bushing?

LodiWino BOY you are having alot of problems. First name would be nice. Here's the thing, you can reinstall the helicoil back in the hole. You need the red threaded loc-tite and give it 8 hours to cure before trying to install a bolt
The problem I have found is there is no pin, or spreader to lock the threads into the bolt hole. Over heat cycles they will loosen again. I have converted my blocks over to timecerts in aluminum blocks. When installed they lock into the hole and don't come loose. They are steel sleeves and can work in any hole, wet or dry. They set below the surface of the block or heads. They come in a 4 piece kit or get a master kit. Fine and Course threads. I have not had one fail in 7 years on 482 motor. I have had helicoils fail in my heads, reason for switch. Think about the cost of replacing the motor, helicoils are cheaper and in MOST cases work just fine for LAWN MOWER MOTORS. For a 15-40k motor is going cheap worth it??? Good luck Rick L. Ps we repair blocks ands heads with timeserts for GM and have not had any failures from this repair. 140 pounds on head bolts torque in diesels. This is alot cheaper than replacement of main parts.
