[EdinR-DrugB]

Hello there,

anyone - need to know a proper way to do this ... something is wrong when i did this,smoke comes from the back ... something is not right!

the way i did this is - pipe from a valve cover into the can ... lower pipe into the can and put a filter on top of the can!

may you help me ... pics or tips!?

Thanks in advance

Can you get us photos?

If there's two ports on top, one should connect to the valve cover, the other to the intake.
Since the st205 has a drain back on the stock system, if you have a lower pipe on the catch can, then it should be connected to the drain back line.

sorry cant insert pics ... dont know how

it is 2 port can same like this one - https://www.ebay.co.uk/itm/2-Port-Oil-Catch...872.m2749.l2649

right port is IN port - valve cover pipe goes there
left port is OUT port - lower pipe( i thing this is drain back line,coz is coming from the crankcase of the engine ) goes there
and on top of this is the filter

Can you go back to the stock one?

I had an issue with the catch can on one of my engines. If I vented it to atmosphere, it would smoke out the exhaust. If I had it hooked up to the intake before the turbo, it would not smoke.
