Without relocating the pcv line and crank vent tube to the un pressurized sized of the throttlebody
I was running only the 2lb spring just to see how ot all ran together... but i think this dimg dong had the wasegate turned in half way

1. Would it throw of the boost /vac guage alot?
2. How bad would of affected oiling?
3. Any other negatives possibly associated with that would be appreciated

Thanks gents

 

Anyone?

 

Lol.... ya i struggle getting my pojnt across at time.

On a boosted motor..... you have to relocate the pcv line and crank vent tube.... both come out of the valve covers and connect to the throttlebody.... which is now under preasure because of the turbo. Both lines have to be relocated to the intake tube before the turbo.... which is not under boosted pressure.

Just seeing if anyone had some input about the affects it would have on the things i listed above

 

Ya no Maf

Also.... on a NA engine.... the pcv and crank tubes are negative preasure i am pretty sure, but if i keep line in stock location..... those lines now recieve the boosted preasure. Hense the need to relocate them to the non boosted intake tube part.... so they then recieve that drawing power...as to draw out the crank case preasure. ... Instead of something pushing that preasure back in. So hoping putting them lines real close to the turbo gets me the vacuum on them lines i (think) I need....so i am now thinking placement is key.....how far or close to turbo.

Yes i too was thinking of a catch can.....but with where the turbo is ( highest point on top of motor)and the oil return line gojng straight down and plumed back into the fuel pump blockoff plate ( for old carbed fuel pump) . This design has worked well for other using it.... no excessive oiling.

So, you think oiling wouldnt be greatly affected with the improper setup lines. I just remember the engine builder not being happy when he checked vacuum. ....totally forget how much o was at idle....dam

 

I mean in the engine.... like would the added preasure....that i dont want....screw with oil flow throughout the motor..... like starving bearings etc.... maybe keep the rockers from getting oiled,etc

 

Yup no ABS.... had to remove the A/C to fit tue turbo and downpipe in.

Thanks for the bungholio advice lmao.... you figute 12" . Sounds good....dirty but good lol.

So as far as negative oil stuff.... it'll force oil into combustion chamber .... blowing by the rings. Yup not good. I was thinking worse case scenario and bearings starving etc.... thanks for clearing it up a bit.

Catch can....lower than pcv location.... good to know.... didnt have any clear direction on that before.... so that's
done now ( in my head lol)

Thanx for going through ot with me ....and bearing with my hard to understand points lol

 

I would run a dual line oil catch can, which is dual in and single out, and then run that to the port on the TB. The boost pressure is going to push into the intake and shouldn't be able to pressure up the line, and the way I see a lot of people run the system. It's just my opinion but the way I would run it.

 

Really eh. Back into the tb? Dual in ....single out. Both the crank case vent and pcv lines into the catch can. ..and one out to the tb. Boost preasure wont go back into the tb eh?

Ya tony that crankcase preasure was always my concern..... and it affecting the oiling of the engine. Not starving the engineof fuel.... but of oil.

So ... gots me a solution appreciate all of this input.... learned somthing and got my fix so to speak lol

 

I mean you could run it into the intake itself , and I would think your motor is going to take all it can and shouldn't back feed, but if you are really worried about it you can put a one way check valve in the line so it can't go that way.

 

Ya see i hear that i HAVE to use the one way check valve.... if plumbing back into the tb or intake .. if I wanted to go into the air intake( before turbo) the check valve aint needed. I only know the stuff i have read though..... havent been through it. So really appreciate the input.

But in both cases, either plumbing it back into the tb/intake, or i to the air i take before turbo ... i have heard using a seperator is a good idea.6

I was just curious though..... in my first post..... what are the negative affects to how haveing this currently hooked up wrong...


Will it really through off my boost/vacuum guage....
I now know what the effects on lubricating the engine will be
Any other negatives associated with driving it like that

Appreciating the input guys!

 

My thing is as Tony stated, I wouldn't plumb it before the turbo because the oil it is pulling will go through the turbo which I wouldn't think would be good. I wouldn't think it would effect your gauge what so ever, where do you have your line hooked up going to your gauge?

 

Okay wont affect guage..good to know. I have it it plumbed into the back part of the tpi.... pretty sure its in the plenum part of it.... so no buffeting air. I just figured that with the lines hooked up (lets call it currently incorrectly lol) , as they are now.... the added crankcase preasure.....would some how through off the boost guage.

Ya definitely want to add the catch can. .... even without the turbo....i seen alot of water come out of engines with them in place.... great idea for any application for sure.

Tony ....boosted engine or not. You know engine dynamics and, I really appreciate your input....keep it coming !

 

I truly believe in the catch cans and there is a knock off of the Mishimoto (which is what I run) on either Amazon or eBay for around 30 bucks. It's worth every penny
