When I applied the Loctite with the clamp fully loosened, it wicked along the splines pretty well, and did pretty much coat all or most of the length of the clamp to shaft contact area. When the parts were separated, the residual Loctite was visible, and it was pretty easy to see how far along the splines it had gotten.

Latest update on the Loctite 290 flexplate fix. I started my TB winter project and checked the TB wear and flexplate movement today again.
Loctite was used in 2005 at 110625 miles. Now 4 years later and at 135625 miles there is still no flexplate movement.
The thrust bearing was checked last time in fall 2004 and was at 0.27 mm (wear limit 0.4 mm). Today's measurement was 0.25 mm (0.02 can be neglected as measurement error).
Looks like a very healthy GTS engine

re: applying heat
Wet towels or rags draped over/attached to adjacent surfaces are your friend when applying heat to a localized area. They make good heat sinks.

Schocki: I can't find a description of how you checked the crank endplay. Did you break the Loctite bond to free the flexplate or did you just pry the flywheel with the clamp still locked down?

Loctite 290 update after 7 years...
Checked my flexplate again today. Since 2005 and about 45000 km (28000 miles) no movement
Thrust bearing check: no changes still 0.27 mm. Total miles 224000 km (140000 miles)
Pretty cheap and effective solution (no PKlamp available in 2005).

Its interesting that the data sheet on this shows a significant loss in lock grip over time.
Id say 100c isnt an unrealistic temperature down there, and after 1000hrs (30k?) you would be down 35% in grip.
Exposure to motor oil exacerbates the degradation as well. (so no leakers!)
That may not be too much to still not work, considering the immense surface area in play in the clamp.
If you were to use this, the spec for wiking into a seal:
For Porosity Sealing
1. Clean area and apply localized heat to the area to approximately 121°C.
2. Allow to cool to approximately 85°C and apply the product.

The transaxle will be fine for a long time. The car received new torque converter bearings, rebuilt torque tube from Mark Anderson, all seals were changed and a flexplate that was secured with Loctite 290 in 2005.

Exactly Loctite 290 is designed to be used after assembly. So far it works just fine. But I would go with the PKlamp option today. Back in 2005 there was no PKlamp and no real solution to the problem.

Great to hear the loctite is working so well for you!
Happy New Year,
