574 does not form a breakaway bead. The break away bead is the portion of the glue that squeezes out and forms on the inside of the two joined parts. When hardened the 574 forms a bead that must be scraped off (you almost need a chisel). For those of us who have rebuilt engines that used 574 you know what I mean.
Next: If the product is not dry, when the engine is started the product will take at least 1 hour to cure at temperature. That means, any 574 that the oil system ingests will travel though the oiling system for at least hour hour before it can clog any oil hole. The engine oil should circulate through the oil filter at lease 20 times in that hour.
Final issue, according to Loctite, 574 will only hold pressurized fluid (read oil) in a gap of .010". It is rated @.020" for seepage but only .010" @ pressure.
Here the point, the oil spray bar holes are .034".
How can 574 seal a hole that size ?
Inquiring minds want to know?
Only the oil in the case bolt above the #7 main bearing is upstream of the cam feed line that feeds #1-3 cam housing. . #8 main bearing feeds the crank. All other case through bolts feed main bearings and squirters.

Not to turn this into a lovefest
, but it's this type of stuff that makes me defer to Henry. Sure there's lots of experienced opinions, but when my tiny brain gets twisted in a knot over minutia I breath a sigh of relief knowing I can follow his experience.
(or maybe I'm just kissing his a$$ because I have boxes of parts on the way back to me
).
