2003 3.0 head gasket repair

Howdy folks My wife's 2003 x5 has been loosing oolant. Now visual milky water on oil cap. I was wondering if this is a common problem. I assume its a head gasket and not a cracked head. Any advice would be appreciated. Do I replace head bolts? use studs? Are there good better best gaskets?

The chocolate milk on the oil cap can be from excess condensation inside the motor possibly from a plugged up oil separator. This is not ness a sign of a blown head gasket. Unless the dipstick looks the same as the oil cap you should look for a coolant leak elsewhere.

Dip stick looks good as does the oil. It would be nice not to need a head gasket. I plan on just keeping an eye on it till the weather warms up.

+1 on condensation, check your CCV. Coolant loss is often caused by a cracked expansion tank.

I would have to say No, she only drives about 10 minutes to get to work. I don't think it has reached operation temp but once or twice a week

My wife's X5 was doing the same thing and it was just because the temp wasn't staying high enough. I began warming my wife's car up before she headed to work and "POOF" problem solved.

I would not suspect these two problems to be related. You may have a leak in your coolant system but probably not into your oil. The oil is probably just not reaching temp for long enough. With that said it is hard to tell where your coolant system. If it was dry out I would suggest throwing some flour under your radiator and looking for blue to trace it.
