I am in the middle of pulling my intake to try to clear the secondary air ports enough to get rid of the error code.. when I pulled the CCV hose, this is what I found.. I am not knowledgeable enough to know whether cars that don't smoke at idle do or don't have this amount of oil here, but it sure seems excessive to me. The tube had a lot of oil in it as well.

i currently have 2 pickups, 1 van & 2 cars - I've probably owned 30 + cars in my life - I've probably worked on thousands of cars & many more trucks - No, it is not normal to have oil in your intake - My BMW is the only one.

Cleaning carbon in a gasoline engine is pretty easy. Run the engine at 2000 RPM with the air filter removed and spray a mist of water directly into the engine for a few minutes.
You can run a gallon thru in about 3 minutes. If you run too much water too fast you can certainly grenade the engine so do not get anxious and spray it in too fast.
Use a nozzle with a control valve that lets you set your spray pressure and leave it set.
If sprayed in a mist, the water will mix with the air and fuel and blast the carbon out of your engine. Your exhaust will have a large cloud of white smoke and that is normal.
This trick has been used for 50 years to clean out carbon deposits.

As the fuel companies tried many formula's over the years some of them carbon ed engines really fast and this trick cleaned them out. For a while in the early 90's the fuel in California was so bad people that did not drive the freeways and took only short trips had carbon build up so bad it turned the back of the valves into Tee Pee's made of carbon.
This trick cleaned those up.
The 95 Suburban I had back then carboned up till it would not pass smog due to high Nox, this fixed that too.

I used to drizzle water down the carb when I had hot rods and older cars.Not done this with newer cars.Good idea!

Sorry i haven't been able to be engaged in this conversation for the last week, I just got back from Cancun.
yall have been a very talkative bunch here!

the *ONE* thing you are forgetting to remember here guys:

air leak.
air leak.
air leak.
air leak.


Question:
what happens when an unmetered air leak is ingested, post mass air flow meter? A B- you should have keyed in on that immediately if you work on fuel injected vehicles.
a little is normal. most every car has a VERY small amount of leak. no big deal.

but, what happens when more air is pulled in? as in, enough to cause oil problems as you are theorizing?

From a novice point of view... this has been my position since learning of what happens when there is an air leak. All other discussions have focused on oil seeping past the seals into the combustion chamber. CCV air leaks causing oil to pass through the vent tubes into the intake.

But I say as well worn seals create opportunity for air entry into the valve cover there for a "air leak" , the rest is history.

Im asking that question because I know the answer.
Im asking it to see if others do as well.

I agree a BIG air leak in the crankcase will cause the CCV to stay open when it should close.Easy test ,close vacuum source on intake to CCVs.Leave hoses open to vent from CCVs and see if you have smoke.Easy.Let it idle for long duration and rev it every so often to clear the residual oil.This might take 2 or 3 hours if you have a quart or more in your intake LOL.If it still smokes its rings or valve seals.

Also I understand that BMWs now have a sealed crankcase this is why leaks down there will cause the CCVs to open.I would like to get back to why higher valve lift helps idle and why you would or wouldn't make more vacuum or pressure difference with higher valve lift .I think back now and I know longer valve open duration as in an aggressive cam can lower vacuum.

i did miss you Big Ugly - As you can see, I even directed someone your way - Even though you didn't take me to Cancun - Now try to keep it civil.

I have to admit I did make a mistake. The pad/filter and screen I installed on the outlet of both valve covers (at hose connections) held oil after the engine was shut off. This was evident after I installed my clear vent hoses and watched the oil flow after starting the engine. Any oil that couldn't drain from those pads, immediately went into the vent plumbing/intake. As I said in a previous post, the OEM vent tubes are corrugated so they don't drain completely either. After removing those secondary pads/screens and with my clear vent plumbing - I am very happy with the results. I can see no measurable amount of oil getting to the intake at startup. Remember, until the crankcase reaches the desired vacuum state, you will have a sudden rush of air heading for the intake. I'm wondering if the hole problem with these engines is the corrugated plumbing they utilize. (As well as bad CCV diaphragms)

dude-

think about it.

what happens on an OBDII vehicle if it has an excessive air leak post MAF?
please tell me you know. PLEASE.

I take it back - I didn't miss you.
The N62 employs a hot film mass airflow sensor, but the MAF can't measure air mass on it's own. With additional sensors and inputs, the engine's ECM can determine the mass flowrate of intake air. The ECM then will control fuel, timing, etc. Airflow is controlled by the throttle valve during the starting procedure when the air temperature is between 20 o (C) and 60 o (C). If the engine is at operating temperature, it will be switched to non-throttle mode approximately 60 seconds after start up. In cold conditions however, the engine is started with the throttle valve fully opened because this has a positive effect on the starting characteristics. It also ensures a constant vacuum of 50 mbar in the intake manifold. This vacuum is needed to exhaust the blow-by gases from the crankcase and the fuel vapors from the activated charcoal filter.

My wife is taking the car to LA for a few days. It's a good trip to check oil consumption & try to clean the pistons again. My vacuum measures fine at my dipstick, but I purchased a new oil filler cap so I can tap the old one with a vacuum gauge. I'll also tap my vent hose assembly to fit a vacuum gauge - just to see what the pre & post CCV vacuum is.
** Also keep in mind, my car runs great **

A B able if you check your vacuum it would be cool if you could also see what your valve lift is set at.

Unless there's a way I'm not aware of without removing the valve covers - Sorry, not unless I have to. I'm wasting way too much time on this car as it is.

how about you answer the question? any person who works on cars that are OBDII should be able to answer this question without any trouble.


what happens when air is ingested by an engine that is UNMETERED?
This specific question KILLS any "air seeping past seals causing oil burning" debate.

Let me guess the answer you're looking for;
The engine runs like poop and the check engine like comes on?

So I just spent 20 > 30 minutes with the owner of AGA. What an impressive operation he has - and a very nice guy. (schpenxel - I'll be PMing you)
