- For 100 pounds you can fit a basic but fully functional breather system and catch can to stop oil and water getting thrown back into the intake system and lowering the octane rating of the petrol.
With oil vapours being mixed with the fuel it can lower the octane of the fuel, add that to the extra heat on track and predet is a real risk .
My last video highlighted quite a bad oiling issue on the Subaru.
The new ej21 had a baffled sump but the stock oiling and breather system.
I was advised by Andy at Scooby Solutions that it might need a breather system/ catch can.
So I fitted a mishimoto 3 port and my own cheap line setup to spend less than 100pounds fixing the breathing.
Thank you so much for showing the routing!! I've been trying to figure it out and you made it so simple. Cheers from across the pond!
Really pleased it was helpful! Cheers!
Great idea having two systems in one, so far I only have a catch can for my pcv system. I need to empty it every month or so. Mostly water from condensation in the crankcase, but definitely don’t want it getting mixed in with the combustion.
It took a while for me to get my head around it but it’s simple in the end. Cheers man. And yeah I think this is mostly condensation
I liked your drawing of the digital camera
Or just leave the PCV connection alone and just connect the valve cover breathers to the catch can. It's only the oil that gets sucked into the engine under boost that matters, and that all comes from the valve cover breathers.
Another great and informative video.
Cheers man!
@@InitialB All your BH5 videos make me wish I still had mine! 👍
I want to install an oil catch can from crankcase valve and head, but i plan to let oil catch can out to atmosphere, and for prevent MAP errors, gonna cap the inlet port which should be connected to valves, and finally the exhaust gas from the crankcase will not flow into the inlet at all, i plan to do this but not set yet, maybe you have some opinion to help about it?
By the way, nice video made, it shows a safe way to make this system!
@@mr.sn1mperdcat276 I don’t see any issue with doing it to atmosphere the way you have described. I think because I had to option with my catch can to flow out I just used it.
@@InitialB thanks for reply mate! I'll give a feedback when i done with it
Nice video, one of the easier set ups and installs.
Quick question, on the drivers side breather, where the new pipe was fitted, what happens with the original pipe, is it capped off ?
Thanks
Yeah if I remember it goes into the turbo intake pipe, that’s blanked.
How much oil can a catch can catch if a can can catch oil?
Didn't you mean 'How much oil can a catch can catch if a catch can can catch oil?' ? :)
I tried so hard, and got so far, but in the end it didn’t even matter…
Hahahaha
Nice combi spanner
Haha yes. Comes in handy!
Hey man from New Zealand here. Love your wagon. However more a fan of the sedans. What are the differences between rev a c b and d legacys. Have heard rev ds have bigger turbos and ecu is easier to play with on the rev ds.
Hi man , cheers.
I had a sedan in the gen 4 and yeah they look great. The a-c have turbo differences with the C being the largest.
The D has negligible difference in turbo size, although a tad smaller. But they come in better and have a better ecu. Also faster steering and a few other improvements. The front is facelifted on the rev D too.
🤓👌👌
I think that's oil mixed with condensed water
That would make sense
what if I want to vent to atmosphere how do I go about that
I’m not sure how you could tbh, because the inlet draws the vapours out the crank and heads. I’m guessing for vent to atmosphere the heads could be open but you run the risk of unmetered air. Sorry I couldn’t be more helpful.
