Oil change after intake valve cleaning?

Quick question, searched and couldn't find the answer...do you need to change the oil after doing the carb cleaner intake valve cleaning? I thought I'd read somewhere that there was a possibilty of carb cleaner getting past the the valve seat and contaminating the oil. TIA

I'd not worry about it. First, the amount getting past valve seat and piton rings will be minuscule. Second, it will evaporate from hot oil

Awesome, thank you.

You don't "need" to do it, but it's obviously a good idea; especially after seeing how bad the valves look before a good cleaning. I wouldn't want any of that stuff floating around in the oil any longer than necessary.

All done.

I wasnt super worried about the gunk portion. I just didnt know how the carb cleaner and oil would get along if some got past the valves and if it would get past the rings. That being said, my car has 90k on it and Id be shocked if it had ever been done before.
