Pulled my catch can and found this

**Greg095** · 01-16-2010, 05:46 PM

I'm a bit worried. Not sure what to think. Any ideas? It looks like somebody melted a milk chocolate bar in the catch can. The catch can was not tight so I'm guessing moisture got in there. Hoping its not a head gasket. Thoughts?

Ummm...not good, but its prob condensation mixed with the oil

From what I've noticed on here, it seems to be semi-normal during the winter. I keep seeing posts on here about a similar chocolate-milk type mix and the answer almost always seems to be, "it's normal, because of the winter". I installed my catch can in late October so temps were down to the 50's and 60's, which was unusually high for that time. At first, I just had a little oil. Then I changed my oil in December so I went to empty it and whattya know?! Chocolate milk. I was nervous cause for a Chevy, chocolate milky oil means a blown head gasket or a crack in the block somewhere. However, since this is only in the catch can and not in my oil pan, I'm sure it's just the colder air causing condensation then getting foamy because of the air passing in and out of the catch can. My car is running great and I'm not loosing any coolant or anything so that ruled out a cracked block or blown head gasket. I'm sure someone smarter than me will probably come up with a better answer though.

edit**also important to note, the catch can does tend to fill up quicker when it's colder so maybe check/empty it every other week or something like that. I get paid on the 1st and 15th so I try to do it around then. Just a handy reminder for myself.

how has the car been running???? could very well just be some condensation in the can....

**Greg095** · 01-16-2010, 06:40 PM

The car is running great.... Well as great as can be expected in sub freezing weather. I just drained the oil and that looked as it always does every 5000 miles.

Normal.......when it's cold out the condensation is bad in the catch can.

What he said^^
We see it all the time this time of the year in our shops. Out of 40 cars in a day we may see 15 with "mayo" (thats what I call it)

Almost looks jelly-like. That would put a scare into me, too.

**Bryali** · 01-16-2010, 07:03 PM

Haha, if we keep this up, we'll have a full lunch pretty soon. Chocolate bar, cupcakes, chocolate milk, jelly, mayo......

**FloridaRT** · 01-17-2010, 09:39 AM

A new idea for BT............. make a heated catch can!!!!!!!!!!

Us southern folks don't need heat.
