1987 galaxie starion 21 ft oil turned from chocolate milk to normal white milk

[tightboathole]

So we drained the oil a couple weeks ago and it looked like this chocolate milk.


We put the new oil in and it ran fine. now the oil caps look like this. Is this any more of an indication for what is going on with my engine?

If it is just on the caps. No shouldnt be a problem. Engine just never got all the way hot.
Question is what does it look like on dip stick?

Have you fixed what caused the water intrusion into the crankcase? If so then proabably just need to change the oil and filter a couple more times after running it to temperature.

Need to know what were working on?? Model,serial# etc.
The first one is definatly water. The caps? That could be condensation escaping??
Still something wrong some place? Shouldn't be that much white goop.
If your looking at the dip stick it might not show water or contamination.
The dipstick tube only has the new oil in it. It's not circulated oil.
Your checking the oil level nd not the oil in the pan.
Drain it or pull the filter. That will show what's in the oil pan.
You have an oil cooler in the system?(again what we workin on)

Thats a lot of condensation. I would stay close to land and keep an eye on the oil level. If you have a bad head gasket it could leak enough to get milky but not enough to see an increase in level.

It is a 1987 galaxy starion 21 ft. open bow #983900. It has a 5.7 liter with a omc cobra outdrive. Im trying to figure out if its a blown head gasket or a cracked block?

No oil cooler on that one.
If there is water getting in, then it could be a bad head gasket.
Possibly a bad riser/manifold.Bad gasket on the intake?
Pull the spark plugs and check for rust/water.
Profile, location? Freeze zone?
