Oil in coolant; Twinkie issue?

[megamile]

Just checked coolant overflow on my 2011 Venture/Hannigan (90,000 miles, bought at 80,000 in 9/24); found huge oil in it. (See pic.) In forumsearches I found primary causes seem to be water pump shaft seals and Twinkie o-rings. Planning to repair both locations; parts for water pump seals and shaft are enroute. Can't find proper part name for Twinkie, or part numbers, or kits. Planning to r&r water pump shaft and seals and o-rings and gaskets in Twinkie, then flush well with Dawn and refill. I have noticed no trace of coolant in oil or sweet smell/white smoke in exhaust.

Can anyone enlighten me with info on twinkie seals, gaskets, etc?

Thank you in advance!!

It’s not letting me copy and paste the link. Look on Partzilla listing under radiator hose. It has the parts breakdown.
