how to properly test if oil and water are mixing?

[midge]

right today i had an idiot come and look at my civic i have for sale, he opened the oil cap and looked inside it and there was the tinyest bit of watery oil, it was a bit browny white, inside the engine though of coruse is fine, however being a 'professional mechanic' he said it was 100% gone, his now posted up on a forum saying the car is fucked, ive offered anyone to come and prove its gone they can have the car for free.

however i cant remember the specific test to check if they are mixing, is it a leak test? or something to do with dye?

sniff test?

 

[mini-valver]

Pressure test it.

i told him to compression test it his answer was 'you cant tell by doing that, and its deffinatly fucked, im a professional mechanic'

 

[172Ben]

LOL hes chatting out of his arse then.

Sniff tests i think works by seeing if any oil is getting into the water and thus goes purple or something.

Pressure test, tests for that leak but via a leak in air, so same thing surely?

Sounds cool does this guy

i thought sniff test was for if exhaust gasses are in the water system

sniff is to test for hydrocarbons getting into coolant, Leakdown test will tell you if there's a breach from the cylinder into coolant or oil. Coolant into oil is very hard, it's not at all unusual for condensation to get into the breather system on many different engines. best proof would be to take the rocker cover of and see if there's any significant deposits of "mayo" and if the oil itself is looking milky.

If it's mixing, as Danny said there'd be a fair amount of it under the rocker cover. Certainly from experience the 'mayo on the cap' test doesn't prove foolproof for Zetec SE engines, as 90% of the bloody things do it. All it proves is that you should investigate it, as none means there very likely isn't an issue - small amounts just mean it might be worth looking into.

Post up that he's a professional arsewipe and should he care to substantiate his claim then you'll not pursue legal proceedings for loss of monies through him spreading inaccurate truths. Remember though, if he says he 'thinks' it's gone, you can't get anywhere but if he's telling people it definitely is gone then he's legally out of line without proof.

Hate wannabes. IT is full of them and it's f'ucking tedious at times.

It really pissed me off, 4 goons come to look at the car made out it was an absolute heap and then because i wouldnt drop on the price they said the cars fucked and theve posted it all up, they were all trying to intimidate me into dropping the price or accepting its fucked.
it is NOT fucked here are some quoates from his thread on civiclife

'check water ..... SLUDGE hmmmmm , check oil and guess what cream ,needless to say H/G gone , the responce we got was nah mate all cars do that , its where i washed the engine'
'that punk was soo gormless i felt like hitting him there and then'
'Then tried saying that the head gasket was fine and he'll go get a compression tester to prove. After 10 min's of explaining that he's talking s**t and dipping my finger in the salad cream from the oil cap rad and over flow And Dipstick'

after explaining why his an idiot and why his wrong there were a few replys from forum members saying that there is nothing wrong with it and its quite normal
'there was 4 of us see the headgasket had gone'
'when reved and the car was warm it had alot of white smoke'
i reply wiht alot of stuff then this
'there was 4 of you who could see the head gasket was fucked? and that includes 1 professional? ill post pics tommorrow'

'I was willing to banter on the price but when i have 3 know it alls and 1 professional plank talking s**t then you can pay asking price or go home'

'midge is trying to make me look at c**t but if your at lakeside next sat ill bring the tools!
Glwts '
'hope to see you at lakeside next saturday!'

the thread locked before i saw the replys

I will be up lakeside next saturday and i hope to be seeing these goons.
