Hey I just went out and checked the oil in my car. Well the dipstick had a white substance on it and when I looked into my valve cover it looks like someone put mustard in my car. This substance looks just like mustard and I'm thinking it's coolant. Am I right about this? The area where the throttle body adapter attaches to the the intake manifold looks like it might be wet? Could it simply be that gasket or could it be an intake gasket? Thanks.

Well I guess according to my uncle he said it just might be moisture so no gaskets are leaking.

that would have to alot of moisture then, anything besides oil in ur crankcase is not good, i would look more into it...do u have alot of white smoke and ur exhaust smell like maple syrup, then that would be ur head gasket anyway

Is it using anti-freeze? If not then it's just moisture. I see this a lot in my line of work.

If your crank case oil is contaminated then it's more than condensation...you need to take a look at the cause and correct it ASAP. That mix that's in there now is in no way good for the internals of that motor.

That is very possible. I have heard of that happening in really cold weather with short trip driving. It also could very well be the headgasket, but it could also be just normal condensation. It could also be a leaking throttlebody to egr spacer gasket. Don't assume the worst just yet , but definently get it checked out before driving it.

It could be a leaking lower intake gasket...allowing coolant into the lifter valley.

If there is that much milkshake present, I highly doubt it's just "moisture".

Do a compression test to see if there is a blown headgasket, if not, check the lower intake gasket. If both of these check out, which I doubt they both will, you're in for worse trouble.

I have an SN95 so I'm not totally familiar here, but wouldn't a leak here just cause the engine to burn the coolant, and not allow coolant into the oil?

did you drain the oil? did it all look like that? yellowish green milkshake in the crankcase = coolant in the oil.

bad news #1: blew a head gasket
Even worse news # 2: warped or cracked heads or cracked block.

it could be moisture built up fomr short stints, but i wouldnt never "not worry" about something like that, it WILL wash out your bearings, and have fun changing those.

Ok all kidding aside.

If it was my car I would put my pressure tester on the radiator and do a leakdown test..
It will tell you if you have a leak in areas besides just the head gasket, it will pressurize the whole cooling system and tell the real story about a possible coolant leak..
