Oil in throttle body

[Pyts]

Working my way down to the intake manifold -- I decided to take the TB off. It's got oil coming through, and I don't mean vapor. A compression test may be in order when it's running again.

Common causes, anybody?.. Or just. Piston rings?.. Something that I've never done before and can't afford.

I *can* install a catch can to try and protect the throttle body electronics.. It seems pretty bad.

Oil's not that overfilled. VCT sensors are siliconed into the valve covers to stop leaks..

Can you put up some pics or details about how you route the catch can and what size fuel hose you use? I found oil in my intake so probably will do the same thing

It might just be accumulated oil from miles/years of driving. I installed a catch can on my 2018 Chrysler 300s since car was new. You’d be surprised how much oil accumulates in that can, just from vapors! If car is running fine otherwise, install catch can between pvc & intake. Then remove/soak up as much oil as you can in intake. Then get a good intake/throttle body foaming cleaner (I like Amsoil Powerfoam the best), & fill that intake/throttle body full of power foam. Let it set for 15 minutes. Start engine(it might take a bit to get it firing) & run at high idle/rpm until smoke clears -there will be a lot. Go drive it at speed. If needed, you can give it another cleaning afterwards w/engine running. You’ll have to run throttle by hand as you spray into throttle body, to keep it running.
