429 thundjet milky oil

Hi have milky oil in my 429 thunder jet. D0ve-c heads dove-a block. Wondering if it's cheaper to buy a new one or to rebuild this one. Please help me on the saddest day of my life

Find out why it's milky first.

There will be a lot of engines from the southern states having cracked blocks this year due to having simply water and not anti-freeze in the block during the week long freeze which happened this past winter.

I live in middle Ga. What about you ? Doug

I think it's a given that you have water leaking into your oil. Pull the heads first and check your gaskets, before going full tilt engine buying. Are you, by chance, running MLS Cometic head gaskets? If so, that's probably your area of interest. Unless you are racing the engine, or have high compression(or boosted application), a good set of Fel-Pro gaskets will do you just fine. Check for small cracks in the gaskets between the water passages and the cylinders. Pull the pan and clean it well of any precipitation. While you're there, pull a rod cap and a main cap and check your bearings. Small scuffs will survive for many years, so don't sweat it. If you have grooves in the journals, it's time for a rebuild. If you are goijng to go that route, the machine shop will magnaflux the block anyway before beginning any machine work. This is "the long way around the barn" way of saying just take it one step at a time. Good luck and I'd like to know how things work out for you!
