Water in my oil, where can it get in at?
So i purchased a seized up 01 explorer sport with the 4.0 sohc and tore it apart, found a blowen apart timing chain guide and a bunch of bent valves. Replaced all of the chains, guides, etc, head bolts, all gaskets, waterpump, outlet, hoses, radiator and some other maintnence stuff slapped the motor in and it runs fantastic. I went to change the oil just to do a little inspection for metal and i ended up finding green, streeky oil. I changed the oil and drove it about 15 miles on the freeway, brought it home, and it still ran AMAZING without a single hickup. Pulled it in, drained the oil, and this time it is very green and strreky/milky. The oil is black and dosnt look like a milkshake like a normal blowen head gasket but is green and definetly looks contaminated with coolant. I pulled the plugs and they all look amazing as well with no green/wet tint and they all have just a edge of brown to them. What i do know:
1. there is a small coolant leak from the front cover/water pump that has me suspicious
2. there is water dripping from the muffler but it is clean, clear, and cool and i believe it is just condensation
3. it runs perfect with no cel, hesitation, smoke, steam, coolant bubbling, etc
My question is, where could this water be coming in it? If i understand correctly the intake manifold gaskets cant cause it as they do not transfer coolant. Could i really have a head gasket leak that is bad enough to leak unburnt water into the oil, while having no symptoms. Does the front cover transfer coolant? Where else can it get in at?
