Oil in throttle body

[Dboychandler]

I have to do a alternator change and taking my air filter off there’s a penny sized oil spot in the throttle body. Even the intake it’s self has some oil in it?

Yes. It's blow-by coming from the vacuum hoses connected to the intake.
Completely normal.

Yes that's the PCV system doing it's job. If the TB or plate is visibly dirty, then a good wipe down with some carb cleaner may be worthwhile.

Same problem im thinking about installing a catchcan

I noticed the same thing while swapping my alternator over the weekend. Glad to hear it's normal. The throttle body flap had some oil/grime around the edges. Sprayed some MAF cleaner on it and wiped it down. Now it looks brand new again.

Install a catch can.

Install a catch can.

Yup

Oil catch can installed.

Not too hard. I think you'd have problems installing this using the OEM intake. Everything fits back nicely.
