hi there, I am Cam. I am sorry to hear about this issue.When you say milky, did it look like a chocolate milkshake?
OK, so I am sure you know that means there is coolant in the oil. You changed the intake gaskets and oil. Does it get more in the oil now? To get the oil that bad would mean longer time with the coolant in the oil.
What I would do is watch your coolant level and oil level VERY closely. If you see the oil return towards the milkshake, understanding that it will take a bit to flush out the old oil, then you will need to do the head gaskets. I would add some Lucas oil treatment to help protect the engine bearings from the coolant that was in there.
Ok, the oil was clean prior the change??
How long did you run it following the repair then?
If there was coolant that got into the oil and you ran it for a time then yes it could be from the blower replacement.
Ok, change your oil and filter, then evaluate it again. IF it continues, it means you either have a leaking intake gasket again or your head gaskets are going bad.
OK so you have new oil now, and is it, the new oil turing?
OK, proceed with your oil change and drive it. Evaluate it over the next few days. If you loose coolant and the oil gets really milky then its gaskets. If not then its just a result of your repair. I always change the oil BEFORE starting it after these sort of repairs so the junk that fell in the pan gets flushed out.
