Is it ok to remove all the senors from the intake, the laminova cores and o-rings/washers, and soak it in something like Purple Power to clean grease and oil off of it?

 

Yes. Be extra careful with the cores.

Put some oil on the core orings when you reinstall.

 

Just regular motor oil?

 

This,

i took my cores out te washers off and the orings off and soaked EVERYTHING in a combination of dawn dish soap and some heavier duty cleaner in a utility sink in my garage overnight. then washed everything off really well and let it dry for 2-3 days. the cores hold water inbetween the grooves like no other.

also like nhanson said. when you reinstall the washers, put a little bit of new motor oil on the rubber orings when u install it to help and make sure they "seat"

 

anything kind of motor oil will work. i used a little bit out of a new bottle of oil we use to mix with gasoline for our weed wacker and edger

 

Yes regular motor oil.

If you wanted to be really special you could get some water proof grease.

I didnt oil the end plate gasket, just make sure it seats in the groove.

 

i oiled it for ***** n giggles. never had any issues.
