There's NOTHING normal about that at all  Unfortunately, seasonal weather has nothing to do with it. If your oil looks like a milkshake, it's contaminated with water  Has the motor been overheated?

You have a coolant leak of some sort. Even the greatest amount of condensation due to many aluminum componants and extreme weather shifts should not give you enough moisture to have coffee with cream colored motor oil.
I will get a trace or so or moisture inside MM's valve covers when there are severe weather shifts and that is only condensation.  ------------------

Well you know my motor has ran hotter than normal since I built it.When it is 60 degrees outside it runs about 3/4 on my gauge which I know is hotter than it should but I don`t think its hot enough to hurt it.I don`t have any coolant leak that I can tell.My level in radiator is still full.I guess that I won`t drive it till I drill out them steam holes in my heads.Then I can replace head gaskets too.Thanks,Tony

Hey Tony... (pardon my senility  ) is your motor the later model block with the earlier heads?

I was faced with the same issue, but reversed. I've got an early block with late heads, so my solution was to drill the block (as directed by Trick Flow). There is a coolant passage/head gasket mismatch in your engine, I'd almost guarantee that's where your problem lies. If you intend on running the early heads (smaller combustion chambers, higher compression  ), you may be faced with tapping/pinning the existing steam holes in the heads (which would require the heads to be surfaced), and re-drilling the late pattern using a head gasket as a template. Anyone verify this? ------------------

I have since check my oil around 6 times and it seems that the milky stuff is mostly in my dip stick tube. The oil it self looks good.I also looked at my oil cap and it too had the milky stuff on the end but I can see the rockers and they look clean.V8 Thumper,where are the steam holes located?I`m going to tear the heads off next weekend.Thanks,Tony

The early steam hole pattern is at the 12 o'clock position over each cylinder, and (roughly) the 1:00 position for the late pattern. Check this out: https://mustangsandmore.com/ubb/Forum1/HTML/007553.html You can see the two patterns in the deck, the 1 o'clock holes I drilled. Your block will not have the holes directly over each cylinder. If you decide to drill the block, watch the casting shape of the lifter valley. Use caution as to not drill thru past the water jacket and into the valley... junk block

Not knowing exactally how the water jackets of early cast heads are configured, I can't for sure say 'yes', but I would think so. Proper head gasket choice will be critical as well. Do NOT drill holes in your heads on my recommendation, maybe author a post on the subject and find out what other guys have done with a motor package similar to yours. I'm sure you're not the first guy to put early heads on a 5.0

Thanks V8,I`ve had others e-mail me when I was going to trade heads and said they were using 289 heads on late model block and they just drill the steam holes bigger with a 1/4 in. drill.But thanks to you and your pic I know where they are now.Thanks, Tony

It sounds like you probably have the situation figured out, but you might want to check on a couple of other things also. Make sure that the breather on the valve cover is working properly, and check on the PCV valve also.
You said that the motor was recently rebuilt, so this may not apply: On a worn motor, sometimes a lot of condesation leaks past the valve-guides. Good luck, Kit.------------------

I used to have an old 85 Escort and in the winter the thing would have tons of that white milky crap on the dipstick and in the tube and on the filler cap.It made it very difficult to check the oil.In the summer time the white crap all disappeared and the oil in the pan was dark summer or winter,never really could figure it out but the motor did have lots of miles on it.
