Is this coolant under my oil cap? [pic]
I had noticed some condensation under my oil fill cap this past week. Didn't really worry about it because I had been doing a lot of short trips and the temp has barely left the single digits outside.
Though after I cleaned the condensation off my oil cap I thought it looked a little too yellow...
What do you think? Is this coolant? I have not noticed any milky oil on the dipstick nor under the oil cap. This stuff looks clear until I wipe it away with a towel. It's not green, but somewhat of a bright yellow. I'm running Royal Purple oil which is purplish/black in color normally.

I agree that guessing on this is difficult. How many miles on the oil? A nice long highway run might be in order here.........
Unless you have overheated the engine, the 0630 head on your 98 is pretty darn tough.
But for the $20 or so that Blackstone charges, might be money well spent.

Just had the rear main seal and oil pan gasket replaced, plus put in a new oil pump for the hell of it. Wouldn't think either of those would blow a head gasket/crack head.

Yes, have that oil tested immediately. If coolant is to mix with oil, it doesn't take long to toast engine bearings.

Loosing a bit of coolant virtually guarantees air is sucked into the cooling system when the motor cools. Keep very close tabs on coolant level (motor cold) until repairs have been completed.

For air to get sucked in the motor that would mean the reservoir would have to be empty, correct?

if you are doing less than 20 minutes of driving then that is just condensation. try a 20 minute or longer drive and most likely it will not be there.
If you had a water into oil leak,,the cap would be the least of your worries
it is normal in the winter time to see it on the cap on short drives.
pull the oil dipstick, if it looks normal then relax and have a beer.

that bright in the photo. I would think condensation would be more clear.

Negative, even a slight leak anywhere in the cooling system will render the coolant recovery system, "the bottle", useless. In order for the coolant recovery system to function correctly, the system must be completely leak free AND the 2 way valve mechanism in the rad cap must function as designed.
