I recentley took my supercharger and intake manifold off to install my dual pass endplate on the intake manifold and when i took it off this is what i saw, a black oily substance, at first i thought i blew a seal on the supercharger but i took the plug out and the supercharger was full of oil, i dont know what it is. I dont know if im leaking oil or what. Can someone tell me what is wrong or if this is normal? Here are some pics

blowby?? no idea...

 

this is what happens when you send the oil blow by from the valve cover, pcv system, back into the intake.

look inside the intake tube. i bet there is a oil film in it.

 

i honestly have know idea what you talking about, how did i send the oil blow by back into the intake, is it something that happens naturally or what. Also are you talking about my air intake or intake manifold? whats a pcv system never heard of it?

 

sounds like ur possibly blowing oil past a piston ring, have u ever had the dip stick pop out on you

 

nope never had it pop out at all

 

the tube that runs from the intake tube to the valve cover is a vent tube. It helps blow by vent out of the oil chambers and oil go along with those exhaust gases. This is the purpose of catch cans. to keep nasty griimey oil outta the SC.

 

If he did have a leaky piston ring you could not tell from looking on the intake side of things. That would be more from the exhaust side of things.

 

i think what area47 is saying is thats normal. your pcv system sucks a little bit of oil out of the valve cover and sends it back into the intake manifold.

if you had a bad piston ring or a leaking ring, you probably wouldnt notice unless it was severe. if that was the case oil would be building up on your valves and oil fouling your spark plug on that cylinder. what you have is normal, put a catch can on it and you wont see it anymore.

 

all i know is my blower didnt look that black on the inside

 

ok thanks for the help guys

 

It's pretty normal. Like area47 said most likely from the pcv system. The way the pcv system works is during regular driving that tube that goes from your intake to your vavle cover pulls air in through the vavle cover to provide fresh filtered/metered air to your pcv system. But when you go WOT your rings don't seal as good etc and you get blow bye. That pressure reverses through that tube and pushes itself into the the intake tube. That's where the oil comes from. Also egr and such cause all kinds of yuckyness in your intake system. I wouldn't worry at all about it. Throw a catch can there and move on

 

cough"catch can".....

 

Do you maintain your K&N Often?

Too much oil on the filter will get ingested into the SC...

 

This is why I took off the crank case vent, and detached it from the intake.

I plugged up the intake part, and put a mesh filter (no paper or fiber element, very important not to have one with the elements) on the crank case. It will prevent that mess from happening. It is normal to have a LOT of oil in your supercharger and intake mani like you do. It is also not good to have that much in there, or any for that matter.

 

Then that does not explain why it happens that when you put their filters on your car it coats your maf in oil and throws off your MAF readings. I see it happen, and it happened to cars that I worked on.

They are not debunking the myth, they are really just saying, "If you think so prove it" There is no evidence here supporting their half other than there are no laboratory tests showing that it DOES coat the filter.

A lack of evidence against something is not a sign of support FOR something.

 

Bullshit, It's happened to me.

 

There's one question that hurts their arguement; How come the AEM dryflow filters do not cause this problem?

 

If you have a contaminated MAF you have a faulty burn off circuit.

 

no i just regreased them like a month and a half ago, they should be fine.

no i havent oil my k&n since ive got it so i know thats not the problem

do you have and pics of this to show, im kinda confused in what you mean, is it something like a catch-can cause that is what everyone is telling me to get.

 

True, a faulty burn off circuit would cause this problem.

 

My turbo has a 2" diameter inlet, The filter sits directly on it, At 20 Psi, the turbo is sucking exactly 2.5 times more air than a 2.0L motor will normally. The Extra Oil Is STRIPPED OFF THE FILTER, trust me, it is possible, It ends up on my turbo compressor...

 

was there oil in the intake? .............if so u could be close 2 the same shape my car is in............i notice this 2 late and now my rings are shot..

 

do you really think it could be the piston rings, id hate to rip apart my engine for nothing though

 

i would say most likely not yet.....check ur intake manifold gasket mine was causing oil 2 be sucked in.......how is ur car running?


is it smoking?
