loosing no anti freeze, after it is warm the engine is a little hard to start like the starter has a tough time cranking it over. I retarded the timing just a bit, but don't know what the timing should be. Pointless ignition

my guess would be condesation. Is your car subject to storage in the cold for weeks at a time and then warmed up occasionally? I know that with a wide temperature change, and running your engine to warm it up will leave a milky substance on the inside of the valve cover, and some on top of the heads.

Tell you how bad condensation can be!! My old '64 Fairlane wagon with a 221 V-8 in it had soo much blowby and stuff that one winter I parked the car at the hospital because my wife got sick and when I came back out in 8 degree weather, it turned over but wouldn't start!!

This was on thursday so I left it there and on saturday, my brother-in-law came ta town and helped me pull it home and put it in our heated garage ta thaw out.

To make a long story short, the fuel pump diaphram had frozen w/ "milk" and the diaphram pump rod broke it. Was I supprised, thats when I flushed the dirty sucker out a couple a times. pdq67

You need to warm it up for quite a while, at least a half hour, or don't even start it up.

You probably dont want to hear this, but milky like stuff in the oil is usually caused by a blown headgasket. I suppose it could be condensation, but that would have to be alot of water getting in there.

My 396 has a crankcase eductor sytem connected to the header collector. The tubing is clear. I will have a milky film in the tubing unless I drive it long enough to get the oil hot enough to "boil out" the condensation. Big blocks make a lot.
Guess that means my joy rides are longer!!

Blown head gasket will cause white milky, melted ice-cream looking stuff in the valve covers. Do a compression check and I'll bet 2 cylinders next to each other are very low. Don't let it go too long or you'll be looking at bigger repairs.

If the oil on the dipstick looks ok, I doubt that you have a blown head gasket. Make sure that when you start the car that you drive it at least ten miles so that it gets good and hot to evaporate any condensation in the oil. By the way, most manufacturers do NOT recommend warming a car up by idleing for a while. You should get in, start it up and as soon as it has oil pressure, drive it ! It will warm up a lot faster this way and keep the condensation down. Like someone else said, if you are going to start it, drive it.
Hope this helps,

Yes, the little 221 ford had alotta miles on it, used a little oil, leaked alot more and had lots a blowby. But I ran the little bugger for years that way!!! BUT, as I've said in the past, I never, ever beat on the little bugger. pdq67

my guess about the milky substance would be that your motor is slobbering just slap a super charger on it and will go away instantly lol.
