Water Blowing from Exhaust and water in oil pan

Post by cbabsb1 »

:banghead I am restoring a 1969 Dodge D100. I recently overhauled the 6cly 225 engine. I had the block vatted and bored, the crank ground, new cam, pistons, oil pump and bearings and had the heads completly redone milled, ground, new valves and seats. I assembled the engine and installed back in truck. I started the engine periodically while working on other issues on one ocassion I noticed water leaking from the heater box. It was just detoriated hoses from sitting over the years but I found the heater valve was bad. The truck sat idle for several months while I located a new heater valve once back together I cranked it without problems and it ran great. Today while still working on other issues I cranked it again and as I walked around to the front of the truck water was pouring out of the exhaust pipe. I shut it off and checked the oil and it appeared a little milky. I checked the radiator and there was no water in it, I tried filling up the radiator and it would not fill I then removed the dipstick and it was milky about 3/4 up the stick. I left it out and continued to fill the radiator until I observed milky oil overflowing from the dip stick tube. I replaced all gaskets during the overhaul and the engine have never gotten hot and has probably only ran about 30 minutes over the last six months. any suggestion as to what the problem may be with the new overhaul.

It can only be a couple of things. First, it could be the head gasket and if it is blown you will get water in the oil. Also, another problem could be the head is cracked and you could be getting water in the oil from that. I take it the machine shop did magnnuflux the head before rebuilding it to check for cracks. The last thing I could think to be a problem is the valve seats. The reason I bring it up is that if you had the seats replaced or hardened seats put in, if the machine drills to far they will hit the water passgae underneath the seat. If they struck the water passage while machining your seats your head is now junk, because my machinist told me that if try to weld the hole it will harden the cast iron and and can't be machined again. If you didn't run the truck long enough to break everything in and make sure that all the gaskets are going to seal, it leads me to believe that the head gasket may not have sealed properly and may have started to leak. It is important to let everything run for twenty minutes to break everything in on intial start up. If not you run the risk of this happeining or the camshaft not breaking properly and flattening a lobe.

I agree with birddog, unless you did-not torque the head right
