Leaks have not been a problem so far, not counting injector caps which I feel is installer error The engine has not been a leaker. Now, that CDR is FILTHY! either the intake grommet disintegrated long ago or it went missing because there is so much oil grunge on the cdr, it's hard to get a grip. That's why I started to use a piece of wire wrapped around the cdr to get some grip.
when I installed my turbo I remember the CDR gaskets being very hard and brittle. I think I almost had to pry it out.
