OIL IN ANTIFREEZE RESEVOIR

[fnc7]

CAN ANY ONE HELP ME WITH MY LAGANZA 2.2 ENGINE?
EVERYONE SAID IT IS A BAD HEAD GASKET. SO WE SHAVED THE HEAD AND CHANGED THE HEAD GASKET. GUESS WHAT IT IS STILL DOING THE SAME THING ! OIL MIXED WITH COOLANT ERUPTING OUT OF THE RESEVOIR. ANY IDEAS ANYONE PLEASE? [/b]

[Audacity Racing]

um... head gasket is the only cause of that that i can think of other than some catostophic thing like a oil/coolant channel that has broken through

no idea... good luck though

[fnc7]

THANKS FOR YOUR REPLY ANY OTHER IDEAS?

oil cooler in the radiator? cracked block? cracked head?

[tango]

Apart from all the other suggestions here (cracked block, cracked head, etc) there's the possibility that this oily substance could be transmission fluid. An overheating engine can cause a crack to develop in the radiator and allow transmission fluid and coolant to mix. This is of course a possibility only if your car is an automatic. Is it?

[fnc7]

NOT ONLY IS IT AN AUTOMATIC BUT WITHIN MINUTES IT BECOMES DRY OF ENGINE OIL AS THE RESEVOIR SPEWS THE MILKY WHITE CRUD MIX.
RADIATOR WAS REPLACED AS A PRECAUTION.
HEAD WAS INSPECTED AT MACHINE SHOP TOO.

WHAT TO DO? WHAT TO DO?

ANY HELP OUT THERE ?

replacing the head gasket and throughly inspecting the head leavs the possiblilty of a cracked block.

try "GUNK block seal treatment" and see if things get better before you tear down the engine again.

THANKS FOR THE SUGGESTION !

Okay, so we have established that it is really oil then. Now, the fact that within MINUTES it's dry of oil then this is not something small. This is major. My friend, the honest truth is that you seem to have a cracked block. At best you should be seeing a rainbow-type colouration in your coolant. I am of the opinion that this block is toast.

[fnc7]

sadly the rainbow is chaulky tan in the resevoir,
when it spews it is MT. YUCKMORE

WE VISIBLY DID NOT FIND ANY CRACKS IN THE BLOCK

PLAESE ACCEPT MY THANKS FOR YOUR REPLY........

[tango]

Cracks in the block may only open under the heat of running or may be out of reach in the gallery areas.

[fnc7]

IT NEVER HAS OVERHEATED COULD IT SILL HAVE A CRACKED BLOCK ?

[MMamdouh]

maybe... maybe not, try the block seal fluid i told you about just to make sure... it is the cheapest option to try right now.

honestly.... if it's going dry within minutes.... I don't think it's a crack... it would have to be a significant sized hole between an oil and coolant passage in either the block or the head.

I don't know what the flow rate of a standard oil pump is but I can't imagine it flowing more than a couple gallons per minute at the standard pressure levels.

Do you have an oil pressure gauge??

It would help if you could see how much pressure is being created.... if it's near zero it's a big hole ( say 1/4" to 3/4" wide )

You might be able to find someone that can pressure test your passages or do a boroscope inspection of the passages.

It's too bad I'm up here in NorthWestern Canada as I have a very expensive flexible boroscope which can get into very small holes.

Another thing you can try is to pressurize the cooling system with air, and listen for leaks. This is something mechanic shop would perform.

From the sound of it, trouble may be related to one of the following:

- cracked block
- warped block surface (was this checked before install??)
- incorrect head gaket install (upside-down, for example)
- porous cylinder head (if check for cracks was performed)
- massive crack in the block ??
