I'm in the process of cleaning up after a failed turbo. Replacing misc items and cleaning the remainder. I took the throttle body and intake manifold off to clean and inspect the intake ports. Cleaned them a few years ago and they don't look too bad. However, when I pulled the air hose off the throttle body a bunch of oil dropped out. I suspect that came from the turbo. Last time I had the throttle body and intake off I just superficially cleaned all surfaces with a cloth rag. Now I'm wondering if a cleaning might be in order. I'm thinking Dawn liquid wouldn't hurt it. Thoughts appreciated.

 

With the throttle by wire it's a piece I want to treat carefully.

 

This is the curved portion of the tube at the throttle. Note the residue. Also found a fair amount of oil.

 

I can't be the only one ever to take this part out. It's my second time and second time cleaning intake valves. Last time I had it out, I just wiped it with a soft cloth, but this time there was more oil. From the other thread I may consider a catch can in future mods. I'll take a bit of Dawn and water to it for now. I have a bunch of tubes still to degrease.

 

Well it's going back in today. Used Dawn and water sparingly. Used compressed air to blow out any water residue. Let it dry overnight. If I killed it I'll let y'all know.

 

Let us know. Mine is laying on the bench covered in oil and needs to be cleaned.

 

It'll be a day or so before I get her to a point where I'll start the engine. I'll post.

 

Thinking about putting a catch can on the passenger side to hopefully slow down the build-up. Way way too much oil getting to the intake valves.

 

If I had a couple hundred to spare I would. I probably will later.

 

Washing did not hurt it. Yet anyway.
