Cylinder Liner Sealants
Lotus went from Hylomar PL-32 (Universal Blue) in the 4-cylinder 9XX engines, to Loctite 572, to Hylomar 3400 (an anerobic, not the blue goo). So while they did go back to Hylomar the brand, they didn't go back to the original Hylomar sealant.
The problem with 572 was Lotus' engine assembly vendor's failure to follow the sealant's procedure, and not a failure of the sealant itself. If you have an early V8 that doesn't leak by now, then there's no particular reason to fear the 572. It's a good sealant, but perhaps the long cure time makes it a less than ideal choice for series production.
Hylomar 3400 has a cure time, but it's much shorter than 572's.
Hylomar PL-32 is ready to go right away... no cure time required since it never really cures.
