So ive been searching for days to find what the best way to install a oil catch can for turbo set up. Ive seen some good write-ups but everyone either shuts it down or has a better way to do it. I found a write-up that looks good, but don't want to buy the materials before I know if its what I need.

This is the site that I have been reading up on..any help on if this would work for my homemade turbo setup. If you have any suggestions, tell me where and what they would be so i know exactly what you mean...im still pretty new to turbos, but would enjoy the input everyone has...Thanks

Yes, you should run a catch can. It is not just for keeping oil out of the intake stream but also so that when your crankcase is pressurized under boost you don't start blowing seals. A stock PCV does not work under boost. My old setup was similar to those drawings only the PCV should be deleted.

 

ok..so take off the pcv and just connect the catch can line to the male end the pcv was connected too? is there anything else that i need to install install of the pcv? or can I just connect the line to where the pcv was? thanks again.

 

We'd recommend having two fittings welded on the valve cover, and then using a block plug that we have in stock for d motors. So all together you'd be running 3 lines, two to the valve cover, one to the back of the block.

 

Yeah, I think two fittings is overkill for a stock D15 but it doesn't hurt. No, nothing in place of the PCV. Line from the valve cover + line from the breather box -> catch can -> intake tube. 90blackcrx's setup would be like the next step up.

 

Interesting. what "seals" are you referring to? I know its not related to the turbocharger, as that isn't related to it.

PCVs can run without one, only at certain CFM and boost pressure levels is it necessary to switch.
