water in oil

[grant]

Hello i need some advice on finding how to determine where and how water is getting into my oil. I over heated my motor because my water pump quit working so i think i may have a crack in my block. I let the temp go to 250 befor i shut her down. I drained the oil and ran her for about 5 min and then checked the oil and it was milky. When the motor was running i noticed some water leakijng from the water pump down the timing chain cover can water get into the motor from a cam driven water pump thats is leaking?

thanks Grant

There are far more knowledgable on this site than myself but to answer your question yes water can get in through the pump mine has a mechanical seal on the shaft

Yes, water can get in from the pump, but to be on the safe side I would block the outlets and one inlet and put some air to it and pressure check it, if you hear something and won't hold air you have a problem in the motor, if not then I'd say it's the pump!. No sense in tearing the motor down for nothing!..

Considering Neovane vs. Magnaflow cam driven pumps; is one known to fail more than the other and put water into the timing case?

Never ran a Magnaflow, pumps way too much water as far as I'm concerened, but I still have the Neovane that came on my first boat and never leaked once, used it all the way up until 2 years ago when I switched to a River Rat because of the injector pump!..

Art, do you mean the magna flow pumps to much volumn or pressure? I can understand excessive pressure but i'm ignorant at the moment of a drawback to high volumn other than excessive cooling. Please do tell. thanks, sic syndicate.:confused::)

Think about it, you don't even need a water pump unless you do a lot of idling around, that pump is like a fire hose just idling now combine that with a bunch or rpm and force fed, that's a good candidate for a milk shake unless you have large lines!..

"Oil cools the motor, water cools the heads" Oil takes the heat off of the bearings/crank/rods and puts it in the pan. Are you running an oil cooler? Your "water temp" could be 150 degrees, while at the same time the oil temp is 350! At this point the motor would not "ping" but it would "grind itself up". "Water in the oil' can be caused by MANY FACTORS! Too much header water (at idle), loose head gaskets, loose intake manifold, bad exhaust manifold gaskets, ........ Without any accurate information as to what you have, I cannot guess what your problem may be. "If I'm driving on the radiator, why not use it?"
