weird chokolate like water color out of cooling passages

Post by chirrin »

so guys i have a question with all this , before i started to use the car again it was sitting in the yard for 8 months do u think probably the valve guides got dry and they r not working properly?

and when i changed the water pump i grab the house and stick it into one of the holes of the water passage besides having rust and mineral build up a dark chokolate like color on the water start to come out and i kept the hose in for a while and kept comming out. next thing i did i drain the oil out of the engine to check for signs of water on the oil but i didnt see any.

is that normal or i got something going on?

was it globbed up in little circles? and kind o fwanted to float on the surface of the water on the ground? it coudl have just been dirty i guess. or it could have been oil. what is the back story on this? it sat for 8 months with no antifreeze in it and a bad water pump? is it back together yet?

it was sittin there for 8 months the water pump was not good , now that i put it to work i took off the old w pump and i put the house into the engine water passages to clear whatever built up was inside then that chokolate dark color came out, that car was sitting there with no antifreeze, now a put i new w pump and put antefreeze on it, the color of antifreeze was green and then turned to corrotio color i mean i thing is normal cause the engine was no spotlees clean into the inside conducts of water, i put it back together again and is working, i got another question how does the water pump should pump/release the water on the radiator?
from top to bottom or botton to top? becasue i notice intead seeing the water running it looks like it wants to vomit the water when the thermostat releases

if it is puking water/antifreeze then it sounds like there is a head gasket or a cracked head. the combustion gases are gettign into the water jackets and makign the water too hot and the gases are leaking out of the water and vomiting. what color of water is corrotio?

Thats classic :clap:

Have you flushed it out good? I mean REAL good? An old engine espically one that has been sitting for a long time with 100% water in it is going to rust. You need to spend a couple of hour with the water hose flushing it out real good.

I just did my 01' Dodge & I flushed it out for over an hour trying to get it to clear up.

Oh corrosion, got it. :thup:

Smoke out of the PCV means you have blow-by. Yes, It could be due to a craked head or faulty head gasket. Im leaning more towards a cracked head.... Espicall if it sat thru a cold winter with 100% water in it. Are the freeze plugs leaking?

i wouldnt worry about the corrosion. orange is just rust color. are you losign water when you drive it? does it get hot? i would drive it and see what happens before you jump and say something might be wrong. watch the water level and check the oil level at the same time. if the water gets oily drops floating in it then start worring.

:yt:

Don't overreact just yet, there may be nothing wrong. Rust buildup in the cooling system in an old engine is very common, just flush it out the best you can. Even if a little remains it won't hurt anything.
8 months of sitting is nothing for these old trucks, we've all seen or heard about many that have sat for years upon years that just take a little cleaning and fluids to make them drivable again.
I wouldn't worry about heads or gaskets unless other symptoms indicate a problem. But keep an eye on your freeze plugs, if the cooling system has been rusting out on the inside then the freeze plugs could be pretty thin by now.
