No real need to follow. Just read. Plenty of info already here to put together a good setup..

 

So I am having an issue with my FP DBB Black.

I recently tapped my VC for a -10AN port on the side. Still running factory PCV and hose in the back.

Everytime I take my intake off there is a pool of oil in it. Oil is also seeping out of my bov around the v-band. This tells me the entire IC and IC piping are most likely coated with oil. If I go into boost, when the bov opens it literally sprays oil out.

I have a -8AN oil drain that is my next step to try and fix this issue.

Anyone have any input? Is it possible to put the oil drain on without pulling the turbo?

 

remove stock PCV and make it -10an as well. use a catch can and recirculate or vta.

 

recirc, as in back to the IM without a PCV????

 

That was my next move, but was hesitant since I have seen some people with issues when deleting the PCV.

I can get the -10AN fitting for the rear, but should I install a check valve inline with it if I do? If so, where can I get a check valve to fit inline with that large of a line size? Most setups ive seen with a big port on the back just route into a catch can with no check valve or pcv valve. Also should I just cap off the IM side?

 

The only way to route it to the IM is with a stock Evo PCV valve due to the need to limit airflow for controllable idle. Most check valves will flow too much.

 

Plus boost into your valve cover isn't a good thing.

 

OK. So should I try the -10AN rear port and delete the PCV? Not sure how else to relieve pressure without opening the rear, but then I will have no PCV or check valve.

 

Always check to see that the oil drain return line is pointing straight down. If it's not straight down then it might drain to slow toward the oil pan, and that makes the oil leaks out of the turbo on both side (hot side and compressor side) to the intercooler pipe.
8an is way too small for a oil return line. At least a 10an or even a 12an line is wonderful.
You should see a lot of smoke in your exhaust when you WOT if you have this problem.
I have the same problem when I didn't set my turbo drain line straight down.

 

I have a stock oil drain right now, so its not possible that's its not pointing straight down since its a hard line.

Car doesn't smoke at all. There isnt much room on the MHI housings for a large AN adapter and hose.

What catch can are you guys looking for this setup? Im thinking it has to be custom to accept the -10AN and the smaller hose from the pcv.

 

Saikou Michi. He will do custom. Great prices.

 

I have one of these and -10 lines going to it and the intake pipe. I ordered a 11" 2.75" can and mounted it below the factory intake snorkel area.

asu11, Do you have the old or new style CHRA? Stock or built engine?

 

I have the MHI housing. Stock motor.
