oldodge41 Posted December 23, 2023 Report Share Posted December 23, 2023 Any opinions on oil catch cans? Beneficial or snake oil? I'm on the fence. For a direct injection engine I think they may be beneficial to keep the valves and intake clean. On a single or multi port injected or carburetor fed engine it could probably be a bit of a band-aid for an oil consumption issue causing buildup in the intake and on the valves. I have a 5.0 Coyote F150 and the forums over there are also split on the issue. No, I don't have one, but sometimes think about adding one. I don't think it could hurt, unless it were to freeze up from trapped condensation in the winter and either break or plug the vacuum for the pcv. It is definitely adding a maintenance item. You have to monitor and drain it, although I have read about a BMW system that returns trapped oil back to the crankcase automatically. Not sure I like that either though. Just something else to think about on a grey December day. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted December 23, 2023 Report Share Posted December 23, 2023 depends on the quality of the can as built...like many things there are benefits and like most thing that are made, the cheap knock off price in inviting....son justput one on his turbo equipped road machine.. 1 Quote Link to comment Share on other sites More sharing options...

oldodge41 Posted December 23, 2023 Author Report Share Posted December 23, 2023 Basically it is an oil separator that is put in line between the pcv valve and the intake manifold to remove oil from the air before it is introduced back into the combustion system.

Sniper Posted December 23, 2023 Report Share Posted December 23, 2023 (edited) I kind of look at it this way as long as the hose connecting my PCV to the carburetor doesn't have oil in it I don't need to catch can. If it does have oil in it I probably need better baffling in my valve cover Edited December 23, 2023 by Sniper 1 Quote Link to comment Share on other sites More sharing options...
DonaldSmith Posted December 24, 2023 Report Share Posted December 24, 2023 I looked up "catch as catch can" on the internet, but it didn't tell me what a catch can is. But the guys 'splained it to me. (Keeping it light-hearted.) 1 Quote Link to comment Share on other sites More sharing options...

Ulu Posted January 5 Report Share Posted January 5 I put a different kind of catch can on my motorcycle. It’s more of a little vial, really. Every time I ride it and park it, she pukes out one drop of oil from the water pump weep tube. Quote Link to comment Share on other sites More sharing options...
