After a brazen try of flushing the oil/water mixture out of the engine, It feels like there is something wrong. The car fires up, runs & drives beyond belief. But what the hell ? water is still mixing with oil. I checked the head for cracks before installation and it was good. What is even worse is that water in the radiator seems to be at the same level. IF water is not going anywhere from the radiator, where is it coming from ? I flushed it three times and it is on the fourth now. Could it be possible that there is a crack in the block ? How do I find out that ? I have a spare head that I am willing to put on this weekend and give it another shot but is it worth it ?

TIA

little enough so you'd hardly notice a lower coolant level in the radiator... M10 blocks don't crack very often--heads more so--hope it's the latter.

Sheggaw,

Hmnn might be pressure testing time. Try to find a shop that has a gas analyzser. They can normally wave the wand over the rad cap when the car is running to see if exhaust gas is getting into the radiator. That would mean either a head gasket leak or crack from the combustion chamber into the radiator.

Now since you have oil and water mixing, I'd be real careful on driving. Milky oil can quickly kill bearings and parts. You can have a crack or blown gasket and not have combustion gas into the radiator.

Most likely you have a headgasket sealing problem or a crack in the head/block. Did you carefully make sure that the block's head bolt holes were liquid free when torqueing the head down? If there was oil in the holes you could have cracked the block.

Normally head cracks result in really high coolant temps, or coolant loss. I've personally never seen a head crack that let water mix with coolant but I suppose it is possible.

Drop me a line if you need assistance.

problem, turned out it was condesation. Are you witnessing the oil/water mix on the dip stick or valve cover cap? My problem, turns out, was caused by short drives, never really driving it for a good long ride. I would consistanly take it out for short 2-3 mile drives. I had heavy Milkshake on the valve cover cap. I spent hours checking things. In my case (hopefully yours too) It was only condensation. I started taking longer drives and it soon dissappeared.

Jenn's car had corrosion in a water passage that let water leak out thru a headbolt hole! That took a while to find...

It really is unlikely that the block is cracked, but it's not impossible. For sanity, have an oil sample checked to make sure it really is antifreeze- $29.95 by mail, if it can't be done locally.

Then pressure testing will possibly solve it- but a lot of times, leaks don't leak until you're under throttle. If you pull the head again, try getting the water passageways tested- corrosion can find the thin spots on a casting...

Have you had the head and deck surfaced? On my current car, the deck is original. I have a heck of a time getting a gasket to seal, and even then, I'm lucky if it will hold for an entire track season. (A new motor is bugetted for this winter!)

fwiw,

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
