While changing to the single blade T.B. I noticed that there was oil all over the indide of stock TB when I took it off. Then I got to looking up in the intake and ran my fingers up inside of it and to my suprise it was coated with dirty thick motor oil. What is up with this? Can anyone help me please?

caka,

Seems early on one or two people had this happen. It's oil coming around the blower pully bearing. Not good, no authorized repair by dealer. Install new blower under warranty. You do have the original blower pulley installed don't you???????????

This is an Easy one...

PCV: Positive Crankcase Ventilation...

A little Oil comes in also, not a big deal.
I noticed it on mine too, expected it too.

I think they call it "coke" or "cokeing".

It looks like oil,but it's really not. Most EFI motor's have this problem. It does not hurt anything.

 

Hey Guys!
It is like Steve said just a little oil from the PCV. If any of you swap out the Throttle body you are going to see this. It is not coke or tar you do not have that kind of heat (lets hope not) to break down (cook) the oil. If you ever get the chance to look inside the intake plenum on a Kenne-Bell 5.0/5.8 supercharger you will find enough oil to do an oil change. Well not that much but you can pour it out.

I agree with all those who've stated it is due to crankcase pressure. Most forced induction motors will have this more than a N/A motor.

On the older cars that weren't as sophisticated computer-wise (like my '90 LX) you can run a breather cap which will help crankcase pressure evacuation. It will not be considered emissions legal by the "emissions police", and it may also cause a problem with the computer on the newer vehicles. I'm just not sure.

I run an open element breather on my '90 LX and don't have any problems with loss of vacuum or a funky idle or anything.

Thanks everybody, I guess the crankcase pressure is the answer. This might explain my oil dipstick popping out about 2in one time after a few long hard runs. (this only happend once)
