Question about Loctite?

Red holds a lot better than blue, but you will have to heat it up to get them off. I would think that a lock nut and the blue stuff would be enough, but if not the red will for sure hold them on there.

I use ARP bolts with Loctite Blue and never had a problem...however...in your application with a high RPM 4-Cylinder, you have more harmonics and vibration than a V-8 engine. Larry Morgan, when he ran his 4-Cylinder Fiero with the 151-CID Super Duty Pontiac engine, had the same problem with flywheel bolts loosening.

In the 70's I ran an H/G Anglia with a 300 Ford 6 in it. I tried red locktite, safety wire. extra dowels etc. Every 6 runs you had to replace the broken bolts. I never could get them to stay in. Theyd either back out or break the heads off. Wisk I could help, I know thats not what you want to hear. Its just a harmonics problem I was told.
