Milky white under oil cap.... blown head gasket?

Rsoxs19 · 12-18-2017, 06:23 AM

Last night I noticed a white milky substance under the oil cap. It wasn't there when I changed the oil 3k miles ago. Also the car has been sitting in my garage for 2 weeks while I put VRSF inlets in, idk if that matters. I'm just worried it's the head gasket. I hope it's not because I only have 52k miles on the car. I don't notice an loss of coolant but it could be very minimal. I was thinking about cleaning the cap and changing the oil. Any input?

How has the weather been lately? If you have a lot of fluctuation in warm and cold weather it might just be condensation. just keep an eye on it, Also verify your pcv system, you might need to replace your pcv valve.

It's been sitting in my garage which is obviously warmer than outside and I have taken it out a couple times when it's been really cold out. I also recently installed the RB PCV valve and BMS catch can.

Short trips or weather changes could account for it. Good luck.

It’s called mayo, the condensation from not driving it much, not getting up to temperature or just short trips. I’d take it out on the highway and get it up to temperature and then check on it.

Your OFHG. Is it leaking ?

Coolant can leaking into your oil and vise versa if this gasket goes bad.
