I am assuming your using a stock flexplate. The dimple on the flexplate aligns over top of the blind hole in the crank flange. Good luck.

I've never used Locktite on flex to crank bolts. I never had one loosen either. They are all knuckle busting tight still when ever I disassemble..

locktite is not dependent on bolt diameter, blue works on bolts larger than 1/4.

I (red) Loctite them, regardless of what the shop manual says.

Engineer- Yes, 242 Blue Loctite can be used on larger fasteners, in fact Loctite says 1/4"-3/4" diameter. Some of us, though, lean toward not using it on highly loaded places like crank flange bolts, since it's a "medium strength" threadlocker. Loctite's suggested applications of 242 include: Valve cover bolts, water pump bolts, and oil pan bolts.

I should add that the last 2 bolt holes are so close that I'm pretty sure I have it on correctly. Like I said, the threads almost catch but then I can't turn them with my fingers. Without the flexplate all 6 bolts go in easily with fingers.
How about a small hole file to slightly open up the holes? |

"Blue 242" is intended for smaller diameter fasteners- I think 1/4" and smaller.

You don't need to use loctite on them. Just torque them to spec. They will never back out.

So thats what happened with my TCI flexplate! I agree Red Locktite. It makes a terrible sound when one or more of the bolts come loose!
