how else can water get in my oil, i rebuild this whole motor and i started getting steam coming out the oil fill so i thought that i had a cracked head!!i pulled the whole motor apart and got brand new 95tm heads,it looked like the water was coming from the lower intake gasket but i went ahead and switch heads anyway.so now 30 miles later and the first time the motor really reached temp and stayed there,the motor starts running funny again so i pop the hood and sure enough steam was coming out the oil fill and dipstick again,i know its not the heads or the intake gasket so where can this water be coming from!!!!?if this is not an easy cheap fix this whole truck will be going up for sale witch i would hate to do since i just put $8000 into it, but im tired and done with it and aint going to spend no more large amount of cash on a truck thats worth $500!!!somebody help!! :mad::mad::mad::mad::mad::mad::mad::mad::mad::mad::mad:

sorry to hear that , got to ask ...you made sure the heads were torqued down correctly and also you used "new" head bolts and did not re-use the old ones (they are torque to yield type...one time use ) ?
 






yes and yes
 






k, the only way i could see for water to get in is maybe the intake gasket/s is not right and or the thermo stat some how over heated the engine and cracked the new heads you put on ...but you said it never over heated right but came up to normal operating temp .....really scratching my head on this one.....maybe cracked block around one of the cylinders ..... :scratch:

yea it never over heated and i never had a problem before the rebuild and i sure didnt want to hear that the block is cracked but i think that is the only other place it can be coming from.the block was bored 20 over but i have rarely heard of the block cracking.it runs/ran fine the i went for a long drive (20miles or less)and it got to temp and stayed around there then i came to a stop and went to pull out and it started acting weird so thats when i checked it
 






yeah... i know money is a concern but i guess if it were me i would do a compression test and see if you compression lower in one of the cyl's that leaks down ( maybe a somewhat easy fix,you may find one thats not holding pressure and just pull that head bank and get that head checked for cracks and to see it was leveled right ) the other .... got to be the block and you know what that means ....... yank it sorry to say :(.

... maybe there is something that was over looked and someone can chime in and give their thoughts on it ....
 






This could also theoretically happen if the lower intake manifold is messed up some how.

Maybe if the compression checks out look into that to make sure everything is torqued down good and that the intake manifold isn't cracked or warped. I've never heard of water getting in the oil this way, but I think it is possible. This obviously would be a relatively easy/cheap fix judging by what you have already done.
 






yeah that may happen ....like if the water jacket in the intake cracked on the inside ( inside of engine area) water could escape and run right past the lifters down to the pan ..... good one did not think of that ....lot easier to replace and fix that than to remove a head or block...cheaper to

yea that's my next step it will be tested tomorrow.thanks for the replys guys and keep them coming because I sure don't want to get ride of this truck

has anyone ever heard of our blocks cracking?

Sounds more like a crack in the water jacket. Could happen for any number of reasons. I did have a 302 that the heads weren't torqued correctly(old specs) and it would blow antifreeze into the catch res. but never into the oil. Of course someone could have missed something on the new heads as well(people make mistakes sometimes). I would go over every bolt and make sure everything is torqued correctly(and in order).
 






so i did the leak down test today on the water system,i took a pipe and drill a hole in it and put a fitting in it and connected both hoses both ends of the pipe to to seal off just the engine and tested it.it held 15psi with no leaks for an hour so now im really lost.i might have to try when the engine is hot but don't know how i would pull it off.even if the engine was hot you think the steam would come out the cap before forcing its way into the oil, since my cap is only a 13psi cap?where else could water be coming from?maybe its not water, but im pretty damn sure it is?here is a pic too show how i tested it:scratch::scratch::scratch::scratch::scratch::scratch::mad::mad::mad::dunno::dunno:

what does the crank case oil look like ? milkshake ?? also what does the steam smell like ? if no then it's not water because i would think if your seeing that much steam then surelly the oil has be saturated with a lot of water and would be visable on the dip stick or seeing it in some oil that you drained out of the motor.

but for the leak test ...maybe it only happens when the motor is hot and leaks because the metal has expanded from heating ....cool, and the leak is then closed .
 






yea the oil looks like a milkshake its creamy and last time I drained the oil like a cup of water came out first before the oil

k, well i guess i would start with the removel of the lower intake and see if it's got any visable cracks ( you know the engine is not right and your going to have to start takeing parts off so the lower intake would be the cheapest and easist place to start ) ...if you can't see any cracks take it to a head shop and see if they can magna-flux it for you that will tell you if there any non-visable cracks in it .....if not then the next items to mess with would be the heads ( you have to take the intake off to get to them anyways) .

anyways you look at it it's going to cost you some money to get this problem fixed so starting with the intake ( which i have heard of some that have cracked) will be the cheapest ( only your time and new gaskets) thing to start on .

did you have the heads surfaced/leveled at a shop before you put them on ?? if you did and the intake is ok then i would go back to them and tell them that the machine work was not done correctlly and to fix it .
 






sounds familar

this just happened to my 2002 explorer. first it overheated because my thermostat went bad and that blew my radiator. then i got a new radiator and waterpump and thermostat but the thermostat was defective so i went with a 174 degree unit instead of the 190. then after all was said and done i start it up i get my coolant flowing and bam! the coolant resouviar was empty. it smelt like gas and oil and my oil was creamy light brown. When i went to drain my oil to investigate a ton of water/ coolant came rushing out. Lemme know what it turns out to be im already puliing my engine out with 111 k on it and putting in a new one,: [ .......but only because i found a new 2005 with only 17k on it so im considering myself lucky but good luck and i hope you get it fixed.

yea im going to retest it tomorrow with it hot and see if it loses pressure.the heads are brand new like new cast new everything and was machined for dual valve springs.he checked every thing before he gave them back to me.i think it is a crack in the lower intake or i hope!!
