Are oil catch cans really worth it? Do they extend the life of the engine? Do they increase horsepower?

 

yes no no well maybe on #2 . they keep alot of bypass oil from being combusted. this could i guess limit the amount of carbon buildup and deposits which will in time increase your compression therebye possibly causing detonation . so a clean chamber is a happy chamber . plus the cleaning of the ic is less frequent . do a search on the $16.00 catch can . it works just fine .
