i also checked my timing and its perfect and while i did that i just ended up changing timing belt.

 

 

Do you have an oil pressure restrictor installed?

How's your oil return?

It looks like your PCV setup isn't correct. You have it so that your crank case can't breathe under boost. Disconnect that catch can from your IM nipple, plug the IM off, and hollow out your PCV valve.

That's where I would start, then go from there.

 

how much boost are you running? Sounds like you might be getting a bit too much blowby.

 

First off you need to take the one line from the intake manifold off and cap it.... you are pressurizing your head and block when you go into boost. Start with that... also another thing to look into is an oil restrictor to go on the oil line to the turbo.

 

Hopefully it wasn't a chinese turbo you had rebuilt. I doubt its the turbo though, since a bad turbo will usually smoke out of boost instead.

Sounds like your HG is the main offender. Coolant systems usually opperate at 16psi, meaning a bad HG will want to push coolant into the cylinder until your turbo pushes more than 16psi. Burning coolant makes a thick, white smoke. A bad HG would also let air push into the coolant system during the compression/combustion/exhaust strokes, so check for an overflowing/empty overflow tank.

I also wonder why you have a catch can, but didn't route that 'breather thingy' hose to it as well, or just used that instead of that top hose. They tap into the same chamber.

he still has the pcv valve so the intake manifold wont be pressurizing the crankcase in boost.

 

^^ Yeah true..... I didnt look at it.

I still wouldnt run it like you have though... I would cap the intake manifold and run the open tube to the catch can at the very least.... but you should run the catch can to the back of the block

yea i agree

 

I'm voting head gasket as well. But I would start with capping the IM nipple first.

Also, how does the smoke smell? If it's burning coolant than it usually smells kind of sweet.

 

damn so much info already....

well ima look into all the stuff... ok as far as the pcv valve tube going to the catch can thats correct right?

and where would i run the other hose that i have going into the intake manifold then?

the breather hose coming from my valve cover your saying to run into my catch can as well?

ok well actually im going to get a smaller spring for my wastegate if i can find a place around here cause im boosting 12 on a stock motor ima go down to like a 8lb.

and as far as headgasket nah its not that its good the smell is not sweet and im not mixing cooland with oil and my rings are all good!



keep the info going!

 

by the way there is constant white smoke coming from breather tube even when idling...

and no oil on exahust side of turbo or in intake mani hope that might help a few of you...

as far as restrictor yeah im good with that i have that!

 

Okay, so take your PCV valve out, crack it open, and remove the valve and spring, then replace it and connect it to your catch can like you have it now.

Then remove the hose from the catch can to your intake, and cap off the nipple on the intake manifold. Leave that side of the catch can open to vent the pressure.

Could it be your valve seals? You shouldn't be getting smoke from your breather. Typically when you do get smoke from the breather, it means your rings are shot.

Hmmmm....

ok well i finally did just that i cracked the pvc valve open removed valve and spring.


here goes what i just did is this correct?

i know all i need now is to connect the 2 hoses from block into the catch can i can T those and make it one inlet into the catch correct. THANKS you guys!


ok so i have my breather hose on valve cover connected to the catch can

i also have it connected to pvc valve.

and i drilled a hole on top of the catch can as a breather but i will put a little filter on it tomorrow its 1130 right now noones open

i also hollowed out the pvc valve.

lmk you guys thanks!

one more question what the hell is the steel wool for that people talk about?

 

steel wool acts as a baffle, it increases surface area which increases the amount of oil caught....

the way u have it setup now is not the BEST but it will work make sure the can has plenty of holes or one large one with a filter for proper breathing... if the can cant vent well than it defeats the whole purpose

 

i am still baffled by the point of a catch can setup like that...

i just took a hose from my breather port, and pointed it towards the ground, i have yet to see any oil come out..

 

i like using the one off the back of the block too. have u done a compression test? just because it still feels fine doesn't necessarily mean that it is fine. ive made that mistake b4.

 

I have the same catch can on my H22, I teed the PCV and the breather together so they are together going to the bottom of the catch can, then I left the top hole open for proper venting.

well mine actually does have oil comming out and quite a bit too so i need this!

 

yeah ive done a compression test and everything was good i actually will be doing another one when i finish my catch can install completly and i also getting a smaller wastegate spring
