some good pictures there! as for cracks in the block, yes you can have cracks that you can't see... hopfuly you don't have any. that water usualy happens when you take the head off cause the coolant passsages are so close. i wouldn't worry about it yet....

Well dont know what the problem could be?

I just sanded the block down real nice with some 1500 grit and a sanding block. I am hesitant to but it back together because it might do it agian. I might need another gasket that goes between the head and intake too.

was there water in the oil?
also pull off the rubber gaskets that surround the timing chain and take a look at them to see if they were or are sealing correctly. it looks as tho it might have been leaking.
another thing just FYI don't use scilicon any more, use "the right stuff" its much more reliable, its very flexible, high temp, and it works 10x better then scilicon.

the profile gasket looked like it was seated right when i pulled the head off, and i couldnt see any places where it was pinched or anything. I have a new bmw one and i will try to glue it in place before i put the head on. The stuff i used was ultra copper but i will try to find some of the right stuff. On monday i guess i'll call the machinest to make sure that he pressure tested this head since i brought in a total of 3 there. He said it was so straight it didnt need resurfacing but i had him do it anyways

yeah good idea to get it resurfaced. i used to use ultra copper, but i switched to the right stuff, its a little more expensive but its worth it.

im wondering how the oil and water were mixing if the block isnt cracked?

kowalski · « **Reply #23 on:** March 19, 2006, 01:38:21 AM »

that gasket keeps them seperated, so if its leaking that is the case.

nickmpower · « **Reply #24 on:** March 19, 2006, 02:35:51 AM »

I'm quite sure that it wasnt leaking though

thats what im afraid of... lets see here... what else could cause oil in coolant...to be honest i really only thing those are the 2 possibilities, a cracked block, or a leaking gasket.

well i talked to the german car shop in the area, and they didnt know what i could have ppossibly done wrong. I'm working there this week so i might see if i can have it towed there.

put profile gasket on
put head on and make sure its seated
put bolts in finger tight
torque in the order in the bentley to 22lbs

I think maybe i will fill the block and head water passages with water. I will probably have to tape off the bottom section of the block, and tape off the t stat housing on the head, but it should give me an idea if anything is cracked, though maybe it would need to be heated to open up?

I've suggested this before and will reiterate it, this problem seems beyond your compentency, so why not take it to a professional to get it taken care of. Hope you don't take this the wrong way... just my 2 cents.

+1 if you can't find the problem now, or the crack then filling it up with water wont do it as the crack will only open with heat and presure. you can get this tested by a machine shop but the block needs to be bare i THINK. you should check tho..
