I took off my valve cover today and i saw that the top of my valve cover was covered in milky looking oil but when i looked on the rocker arms it wasnt that bad only a few spots had it...... well i know that i have a water leak some were in the internal part of my engine i just replaced my driver side head gasket and i replaced all my gaskets on my intake.... the only thingi can remember doing wrong on my intake gasket was not putting any silicones around my middle collant passage..... the only other thing i coould think happened is my passenger side head gasket......


Basically is there any way of telling which one it is leaking my head gasket or intake???????? please help any one... im bout ready to give up

 

pull the intake if there is a water leak there you will be able to see it on the gasket.

 

The coolant passages are on the ends (corners) of the manifold.

Does it get below freezing where you live?

 

no i live in california..... and ur right the middle passage on the intake is for air. and yeah the water passages are in the front and back i siliconed only the front passagebecause the back one is covered and is not in use but i did silicone the front

 

Chevy man, before you freak out, check one simple thing. Im sorry if it sounds stupid but you never know.

Check the oil on the dip stick, how does it look? Then do an oil change if ur not certain. DO NOT START UP THE ENGINE to warm it up. Just drain it as is, because everything has probably settled. Examine the oil that comes out carefully.

If its not choclate milk, you may just have a simple case of over-filled oil, which is now aerating, and becomes a bright colour. My buick used to do that, and youd see a very bright brown coloured oil on the fill cap, and few rockers. It was frothy almost, and Its a sign of aerating.

 

can any one else add anything

 

Do you take short trips? Could just be condensation. Happens to all of my cars now and then.

 

The center ports are for exhaust.

 

YEAH UR RIGHT THEY ARE FOR EXHAUST...... I PRETTY SURE THIS WAS A FALSE ALARM I CHANGED MY OIL AND IT WASNT MILKY AT ALL....

I THINK IT IS JUST CONDENSATION BECAUSE YEAH ITS BEEN RAINING AND ITS SOME PRETTY COLD WEATHER AND I ONLY DRIVE IT EVERY ONCE AND A WHILE AND MY TRIPS ARNT VERY LONG.............
