hooked up egr to crankcase

ok i did it and now when i let off the gas my car smokes white like a mother so why is it doing that? hears what i did same as bevis stated,


Sorry, he said crankcase, and thus I said it too.

Anyway, the valve cover breather. . .I connected a hose to that. Then the EGR tube, I removed. I had bought a plug to put in its place, but I drilled and tapped a 1/4 NPT in the center of the plug and installed a hose barb in the plug and connected that to the breather tube. Sorry, I don't have pictures and it is nearly impossible to see what I did looking at the car now.

STEPS:

Remove EGR tube.

Take EGR tube fittling and find a suitable male plug (or reducer) that will screw into the intake where the EGR used to be.

Drill and tap a 1/4" NPT in the male plug (skip this if you were lucky enough to find the right fitting. . .it may exist).

Attach a 1/4" NPT to 3/16" hose barb fitting to the male plug.

Clamp a hose onto the 3/16" hose barb.

Install the plug, fitting, and hose into the intake where the EGR used to go in.

Connect the other side of the hose to the valve cover breather.

That's what I did. Took care of the "EGR Flow Insufficient" CEL.



but now it smokes really bad like a brush fire under my hood or like a big bong hit (stoned) hummm dont know why its doing it my guess is its sucking oil or blowing oil into the intake manifold has any one else had this happen never smoked before i did the egr thing :wtf:
 
last time i seen smoke that bad, the prob was the CC was burning oil like it was gas.

dont know if thats your prob, but if you had NA and boosted, thats prolly it.
 
as soon as i pull the hose going to my manifold whare egr used to be and plug it it stops smoking after all the oil burns up weird and it smokes after i hit a little boost and let off not while boosting confusing

what do you mean like from stock right is it before your bov or after?

It actually goes right b4 the turbo. I have been told it is bad there because oil can get in the intercooler. I am gonna ask andy if i should relocate it after the BOV.


you can see the black tube heading from the valve cover to the intake.

EDIT: better pic.
 
i dont know because there is no boost there after the bov there is boost and i dont know what that woud do to the crank case pressure probably is what is happing to me forcing air into crankcase and saturating everything with oil?
 
Are you guys talking about the EGR or PCV?

EGR means exhaust gas recirculation. That is the pipe that goes from the exhaust manifold to the intake manifold via the EGR valve.

PCV means positive cranckcase ventilation which are the two hoses coming out of the valve cover. Ones goes into the intake manifold and the other to the air inlet hose between the MAF and the throttle body.

well maybe mr bevis will see this and help me out

That is happening because you are putting the crankase with pressure from the intake manifold when it is under boost. The crankcase positive gases have no way out so the oil from the turbo is building up and oil is getting into the hot turbine housing.

Just plug the EGR. Run a hose from the valve cover port to the air inlet hose or pipe.

yes that is what i mean by crankcase ventilation aka "the little hole whare the filter goes on the valve cover" i figgured it would pressurize the crankcase and blow oil down guess i was correct i figgured since little bevis did it and it worked that i would do it oh well guess ill plug it back up and put the breather on for now. what would happen if i had someone plumb the egr back into my exhaust and put the crankecase vent into the intake side "before the turbo" would that pose any problems? has anyone done this yet?

There is where it is suposed to go. The air inlet before the turbo. Make sure it is after the MAF. If not the MAF will be damaged by the oil. This is done in all our applications and no problem.

ok so the little bit of oil that comes out will not harm the turbo then? and if placed after turbo like in intercooler pipe it will pressureize the oil system correct? just want to varify some things

thanks

where did you say your egr was plumbed to?
was it capped or recirculaed to a different part of the exhaust?

i was confused, i though they were talking about the hose comming out of the valve cover.

Where is the EGR?? I will go look and see if i see anything.
 
Ummm. . .hello. . .now I'm confused.

The valve cover "breather" in stock form, goes into the intake tubing right before the TB. That's all this is doing now.

I have no idea why it would cause an oil problem. Mine works absolutely fine. . .so now I'm confused. I cannot see why this is causing an issue. I'm sorry it didn't work, but it is working fine on my car (no oil problem whatsoever). I've got to think about this now. . .don't get it.

If you are going to un-do it, then I would just put a breater on it.

Does the car smoke otherwise? I didn't follow if it still did a little with the EGR plugged. If so, you need to address the oil return line as you have too much restriction there.

Damn. . .must think. . .must. . .ahhh. . .I don't know.
 
I've been thinking about this, and while I agree that it isn't the best to add pressure to the valve cover, I cannot see how it would cause any harm. :wtf:

(I'm not really defending what I did, but more so, I'm curious how it can cause a problem, especially since it worked so well on my car.) It seems to me that there really shouldn't be any way it can "force" the car to start burning oil. Help me understand.

Svxin, I'm really sorry it did work. I don't understand why. :confused:
