Just finished putting my new motor In ( motor out of my old car) and drive down the road and it got over half and I open the cap and its milky
Just wondering if I have put a hose on wrong that could be putting the water in the oil? It empty all the water inro the oil less then 5 mins

how much custard are we talking about, a little build up on the cap or is the whole insides of the rocker cover full of milky sludge?

Carby or efi?

Cooling hose hooked to rocker cover?

[Scrawny]

My brother did an engine swap many years ago and swapped fuel with coolant lines, lets just say it didn't run well on coolant

As suggested, check for wrongly connected hoses somewhere

I'm confused, are you saying that it used all the water in the overflow bottle or from the radiator?

If its only the cap that looks milky, and the water is missing from the overflow, could it be that you didn't bleed the cooling system properly, and the milk is just condensation?
