Thanks. For all of the talk about valve cleaning sprays and catch cans you'd think we'd have a treasure trove of evidence showing how the LT4 cokes up to high hell. Hopefully someone will get some proof in pictures on this forum soon. I've been debating doing a catch can, but without some unbiased proof (not from a catch can MFG), I'm not sure I can pull the trigger.
