Been over on the RegalGS forum I frequent and have been discussing the top clean procedure over there . The subject of a Pcv catch can came up and someone mentioned that the older LS1's have a problem with this system:

These are the ones we normally use on the LS1, the LS1's dump a lot of oil into the intakes.

Not that our cars don't, i'm going to use the LS1 version on my car only because the PCV no longer functions correctly using the breather with the intercooler. The car isn't really drawing vacuum any more with the breather, dumping a ton of additional moisture into the oil and really not keeping the engine clean. LS1 guys claim it reduces KR and longvity of the engine.

A cheaper alternative is to use a Husky oil seperator for air compressors, cost about $25 from Home Depot. Function without the bling. Summit also sells 1 quart plastic one for $25 or smaller aluminum ones for around $80

Has anyone put a catch can on their LS1's and what were the results if so ? The link in the post above is for a premade billet catch can for F bodies btw .
