i filled the car up with coolant.
then oil.
started ... and she fires right up.
forgot to put the cap on the coolant . no biggie , i think. the car is cold
now, what is that brown goop coming out of the coolant bottle?
tons of it...
then i turn the car of and check the oil again and guess what...?
yepper the dip stick is dry as a burbon.
i fear the worst , but i don't really wanna think about it. i am tired
and it's one in the AM.
but maybe you like to do that for me.
just gimme the news

ok........ I give.

Your day sucked worse than mine. You have a head gasket that blew.

Stan.Shaw@Excell.Net

Does you 928 use the radiator for both oil and coolant? If so, you might have an internal leak in the radiator allowing coolant to mix with oil.

If he is lucky!

Look at the bright side, you didn't have a timing belt failure, So your day now doesn't suck as bad as you thought it did...or could!

Time to learn more about how to work on a 928!

Best of luck.

A lot more likely than a head gasket failure between oil/water passageways IMHO.

Easy way to check is to remove the oil cooler lines from the rad and using just one line attach it to both of the block fittings bypassing the cooler in the rad.

if you get coolant coming out of the oil cooler fittings and the engine no longer looses oil therein lies the problem

Maybe due to the earliness and the lack of light you poured oil into the water tank. lol

With the cap off and no pressure in the cooling system, the oil went through a leak in the radiator in the cooling interface in the left side sidetank. If you had had the coolant reservoir cap on, some of it would have gone the other way once you shut the motor off. So, all-in-all you are better off having left the cap off, as you probably have no water in the lubrication system to try to flush out.

Take out the radiator, have it repaired, flush the cooling system. You're day didn't suck as much as it could have, but this is still pretty sucky. Sorry about that.

i'll check it out , when i get home today.
maybe that's it. hopefully, that's it

As far as I know Bill, those heat exchangers cannot be repaired. And I don't think they are available anymore either [they are built into the plastic end tank]. The only hope in this situation is to find a used radiator with coolers intact. That or add an external air-to-oil cooler.

N!

Here's what I would do:

[actually...what I did]

Go down to Pep-boys and purchase a Hayden external air-to-oil cooler, mount it down in front of your radiator and behind your grill. Run the tubes to the sandwhich plate which mounts between the block and the oil filter. The existing oil cooler tubes? Temporarily bypass them. Order a pair of oil cooler plugs from Devek. Then get a new non-cooler end tank from 928 Intl. and have it installed. Flush your cooling system and do your oil again. Problem solved.

My S2 has been driving around this way for four years now, no problems.

N!

here is a pic.

great....!!!
i just saw there is brown goop leaking from the bottom of the rad as well

69gaugeman

Looks like just a Rad. That doesn't suck as bad as you thought then.

Leaving your cap off may have been a blessing in disguise. You found the problem before the water leaked the "other way" and while you were still in your drive way.

Agreed radiator side tank -- but that's a significant leak, with the stick bone dry, and bone dry is bad for oil pressure and ...
