To a new topic, How many have done the Do it yourself oil catch can yet? It really helps out on diesels and a very good ideal on gas engines to keep the oil out of your intake and clogging your PVC valve.
Here's a few super cheap ways you can do it vs a 3000P or 4000P catch can.
The good old air compressor filter.
Or even cheaper and just as effective (especially for gas engines) use a simple clear inline fuel filter, You can just empty it out whenever you need and requires only hose clamps or zip ties to secure and only 1 cut to the hose.
If you can find one with 1/2" barbs it will work with most turbo diesels. Some are also 3/8" but most gas engines the 1/4" barb will work for you and should be easy to find.
