milkified oil! compression & leak down results inside

[mysharonna]

So I never catch a break with this car...

I have had the car sitting for a couple months and have only driven 1 event in May. I noticed a little bit of white smoke coming from the exhaust, so I go to check the oil cap and its milky.

So I go :picardfp:

I am suspecting head gasket. I run some tests (warmed engine)

Compression results
#1 - 145
#2 - 135
#3 - 155
#4 - 160

Leak-down results
#1 - 4%
#2 - 4%
#3 - 6%
#4 - 8%

I saw no bubbles coming from the radiator during leak down test, although when running with the cap off, it did show bubbles.

I have done a lot of research and can draw my own conclusion, but I wanted to put this up to ask about sr20det common problems. (cracked head or block, turbo mixing coolant and oil etc.)

My setup
stock s13 redtop head & block
cosworth head gasket
GT2871r .64
650cc injectors
freddy intake manifold

It could also be a cracked head.


Once warmed up, any cracks that you had not initially noticed in the head when cooled down can actually reappear.

Did you *DO* anything to the vehicle before this started happening?

I haven't driven the car much at all this year. Its like it just happened all of a sudden. I am thinking about changing the oil and seeing how fast it turns milky again. Its not loosing coolant either, so maybe its really bad condensation..

if its milky its your headgasket lol,
coolants going into your oil mang, change it quick, then you gotta flush your oil so you can get rid of all that.

I figured as much. I am just was thrown off by my leak down test.

Dude don't go nuts...it's just probably moisture buildup especially if you say you haven't driven the car much. Short trips to places often cause this to build up in the oil cap.

Case dismissed.

Thats what I am concluding. I may take the valve cover off and check the head bolt torque, but I don't see it being a big deal.
