I could be totally wrong but isnt that a sign of a blown head gasket?

Im not a mechanic though so dont take my word.

cheers

Yeah it can be a sign of a blown head gasket or a cracked head. Have you overheated it at all? Need to do a Co2 test and compression test perhaps.

Then again it could just be the heat exchanger sandwiched between your oil filter and the block...Doubt it but it could be.

But Head Gasket is metal.

How to do Co2 and compression test perhaps?

Sorry I didn't know about it if you can explain to me how.

You can only do a Co2 test if you have the test kit same goes for the compression test. Best to take it to a reliable mechanic. Where are you located?

Well dear, I have the same thing and have been told it could be little O rings inside a rail looking thing near the injectors that apparently houses air and water chambers...... I could be way of dear, as it may be another problem I was being explained about.

There have also been problems with the oil cooler that sits on the block next to the oil filter, it may have a crack.

But it sounds like its time to drop it by a mechanic. hope its not too dear

Go the same prob at the mo, heads coming off this week to check it out (plus some other stuff while there).

oil in coolant is usually a head gasket.

whats the color of the oil?

Does the radiator have bubbles with the cap off?

[Supra2000]

I already changed the oil cooler next to the oil filter and the engine block.

I want to ask you the head gasket if damaged I think the mixing should be inside engine, Am I right?.

I am thanking you for your reply

[Godzilla32]

Coolant runs throught the entire engine and cooling system (radiator, etc) so a mixture will be spread through the whole system not just in the area where the problem occurs.

is there water in the oil too?

[Supra2000]

Yes there is water

And the mixing happen while car going not when I stop the car (I mean High pressure).

[mad082]

generally the main cause of this is either a blown head gasket, or a crack in the head.

i had to replace a head on ford laser the other weak that had a hole in the head. the oil and water looked like someone had drained them out and filled them with ice coffee.

[Supra2000]

If the oil and water looked like ice coffee it means the head cracked.

It could be all of the above as well as a cracked block . A compression and a leakdown test will confirm any headgasket /cracked head or cracked block and even pinpoint where it is .

a coolant pressure test may reveal your problem as well.. The cheapest option would be a leaking cooler sandwich, next a headgasket, just because its metal it can still leak ( actually that could be your problem if not correctly torqued ) ..
