35d: adding crankcase breather oil separator

[boredincl]

Thanks for the info Seattle, I recent did the ABC delete as well, but also installed the ProVent per the sgrice diy. On the first drive I had a oily mess because apparently I accidentally knocked the top cap loose while I was finishing the install. It really surprised me how much oil was around since i only drove a few miles. the next trip was a bit harder and then 10 miles of hwy driving. while on the hwy I checked the oil level through the DIS and is showed low when i just did a change. I stopped and checked it via the dip stick and the level was fine, while stopped i also checked again with the DIS and is showed normal as well. I was wondering if the increased boost from the new tune was somehow causing the ProVent to cycle oil through and into the pan?
I unhooked the ProVent for now, but will be re-connecting after i replace the exhaust manifold due to #1 port wrapped. it really upsets me because i know it was when i put it back together, but thought the new gaskets would still seal it up.
Anyway... your thoughts on the oil level indication change?
As a side note i very seldom us the DIS to check the level so maybe its just always acted like that and i just never noticed it.

You drilled holes like suggested by ZetaTre, correct? 5 is too many, 3 is correct to get turbo sucking just right amount when filtering.

In my case, before ABC deletes, that was just fine, but increased suction from turbo after deletes, paired with weakened valve spring, caused the valve to close and fumes nowhere to go but through top cap relief valve.

If oil (not just fumes) get sucked into provent somehow, easy way to check is the hose INTO Provent. Normally, the hose would have a thin oily film, but if any oil was passing through, it would be covered in it from inside.

I have an exhaust manifold off a 50K mile x5d laying around in my garage.
Salvage yard where I got the HP turbo was too lazy to separate, so gave me both turbos and exhaust manifold together.
PM me if interested.

I did drill only 3 holes as per DIY. Good point on the amount of oil in the inlet tube, it was oily, but not like a lot had flowed through, but more then just mist, although it has 170k miles so it may have more blow-by then normal.


I will reconnect everything, monitor and then stretch the spring as you have done. Thanks for the offer to sell your extra manifold, but I just bought a used manifold on Friday. #1 port on it is warped away from the head ever so slightly as well when checked with a straight edge, but much less then mine and is something I can take out with mild plaining... I think.

Is there a separate thread on this warped manifold issue? Tune related ? Also looking at getting a tune in the near future, but don’t want to replace parts because of it.

Have people been having problems with the factory CCV with tuned engines? I am planning on keeping the factory system and adding a provent using a fan powered secondary loop, much like Soldberg does for their industrial CCV filters

The tune is unrelated to the warped manifold. I have known my manifold was warped for the last 3 years when I found both exhaust bolts on #1 cylinder were broken.
As for the ProVent and issues after tune Seattle summarized it earlier in this thread, although I’m not sure I would call it an issue or just something to be aware of and make the necessary adjustments.
