Milky Coolant
JUST INSTALLED A DIFFERENT INTAKE ON THE CAR AND I NOTICED AFTER A LITTLR WHILE THE WATER IN THE RADIATOR IS MILKY? FLUSHED IT AND MILKY AGAIN. AM I LOOKING AT A BAD SEAL ON THE INTAKE GASKETS?

Hopefully that's the only problem. You could have a crack in the manifold.
The thing is you are also likely blowing coolant into the oil. Good luck. |
Milky Water
Hi,
One item to look at would be your intake to head alignment. Many intakes, especially if they are used, can be milled to the point that they don't make an even alignment to the head. This will open up the bottom of the intake gaskets to oil into the intake and coolant ports. If this is the case, you problably will get water into the oil also. Normally though, milky coolant water is a function of cumbustion gases or oil pressure entering into the water passages. Head gaskets, or oil feed passages that feed the rocker arms through the block can also cause this condition. If you have any questions, please fell free to call me and disguss this situation.

did not have any water in the oil.the intake was never milled.the car was fine before i switched intakes?
|
white milky, or chocolate milky?
|
white milky. how can i find a crack in the intake?
|
Would like to reopen this thread. I have same problem on my 351C engine in a Cobra. Coolant water is "chocolat milky". Luckily no water in oil until now...
Any ideas what it may be? |
milky
Intake gaskets on the 427 FE were the problem both times
|
Chong,
My first guess would be your intake gasket. I don't have much experience with the 351 Clevelands but I would double check the areas at the rear and front of your intake and whether or not sealant was used. If the cork gasket was used it might be the culpret. The cork seems to be more prone to leaking than silicone. |
For starters take the cap off the radiator or expansion tank. Fire up the motor cold and see if you get any air bubbleing up through the coolant. You could put a radiator tester on it to check pressure. Doing that would tell you if your were getting compression in the cooling system..i.e. leaking head gasket. Generaly speaking if you have oil in the water, you have water in the oil. Im not 100% certain on a cleveland but on the 302,351w,460 etc...there are pressurized oil passages close to water passages (cleveland did some goofy stuff). The oil drains back at the bottom of the head and ou havewater all around that in the block...but you would have water in the oil.
I'll bet your head gasket is leaking somewhere...just my thoughts. |
