My last motor was destroyed by excess crankcase pressure and all the seals on my motor basically started to **** oil. To prevent this from happening on the new motor I have fabbed myself a custom catch can. Using an AC accumulator from a GM car designed to absorb moisture I rigged up my setup. One line goes to the breather box on the back of the block where the stock PCV line goes. The PCV is eliminated and that line goes to the inlet of the accumulator. Then the outlet goes to my turbo intake tube to pull a vacuum on the crankcase relieving all the excess pressure. Comments and criticism is welcome.

looks good.

i gotta do this to my motor.... but imma try the exhaust slash-cut setup.

Also, how do like the 48/60 on your car???

 

diy stuff

 

i was actually at the junkyard today interested in doing the same thing... i like the subaru's accumulators... very light... anyhow, the guys wanted too much for the stuff i pulled out.. so i had to decline.. ...

for the idea... and some of these accumulators have baffles already...
