Any negatives to having a catch tank? Finally installed my 6A/KR rebuild (took the threat of moving out and having the engine still in the garage to do it - haha) and must say I'm more than happy with it. Pulls well, revs hard - muchos smiles all round. The KR used to pull a bit of oil through the crankcase breather, to the point that i felt it could be clogging the air filter - K&N so washable... Is this normal, is it a problem? Anyway when setting the gas (fuel/air) on the 6A, with the breather off it seemed to spray oil over the front of the car.......... Can't help but think a catch tank would be a good purchase... Could i just make one with a panda cola bottle and some hose? Does it need to route back through the intake system or can i just block the hose connector on the airbox? Ta
