Black stuff in intake port?

[Rambro]

Pulled blower and the intake ports in the head has this black stuff in them. What could cause this?

[Roots-type]

Carbon from the egr system

 

[Soap]

Oil from PCV system.

Oil.

You'd benefit from a catch can setup.

I have no pcv for the past 4 years, no egr also. Could it just be from years ago and mabye i didn't notice before? Car dosent smoke but intercooler was very oily before deleting pcv.

That's very minor carbon build up, won't hurt anything. Probably just left over from when you had PCV and EGR.

Thanks for the replies. I'll clean it up before putting it back together.

Oil.

I tried to clean by hand. No luck

Ran 3 tanks with stp fuel treatment

Was back in and it was spotless

Even the valves that you see

Intercooler is also full of junk

Needs cleaning a lot

I took pics but photo bucket has changed and I cannot share them

Did the fuel treatment help with the IC??? Thought I had to pull it off to clean it manually, if not thats great news.

my guess would be oil getting into the system via the PCV

no fuel goes through the intercooler so that won't help, you'd have to pull it and clean it

IC you need to do manually, careful what you use if you're soaking it. There is a rubber piece where the lines come in that separates the inlet and outlet. Don't want to ruin that or the coolant won't really flow through just in and out at the front.

Just runners.

But oil goes through cooler
This is where it gets in
