    Hi,

    Just wondering if anyone would know why my Audi would let smoke out when you lift the dipstick as the car is idling, apart from condensation would there be anything else that could cause it and it is something major?

    Car is 54plate Audi A4 1.9TDI 130 Sport

    Thanks

    I had this from my car when I bought it and so did my brother in law. Mine is a 01 and his is a 03. We are both up around the 100k miles mark. Aparently this is very common with this engine (as long as its not billowing out! :o.k: ), but what reduced it for me was draining the oil, changing the filter, putting in a bottle of "slick 50", then topping up with oil. If you drive with this for about 3k miles, then drain the oil and "slick 50" again and re-fill with oil alone.
    Worked for me anyway but I dont think this phenomenon is that serious that you would have to do this procedure anyway.

    (as long as its not billowing out! ),

    When you say billowing out, what do you mean, its a constant smoke? If its not serious as the car has only 29k on the clock then im happy to leave it but if it is then id like to sort it?

    Well on mine for instance it was just a very light mist coming out. You'd have to look twice to see it. Id say if it's much heavier than that you'd be better getting it checked out. If you put your hand above the open dipstick hole, can you feel it blowing out?

    Not sure to be honest but blowback through the dipstick is not good thing. Is the oil level ok? Too much oil is as bad if not worse than too little as it can damage the turbo. Make sure it's not overfilled anyway.
    After that and what I said to check previously, I cant really be of much more help. Hope its alrite for ya anyway.

    Don't ever put slick 50 into your engine. it doesn't work and if you don't believe me read the following link. The makers of the product have been sued by the American government over claims it can't back up.

    For PTFE to be deposited on metal you need temperatures in the order of 350-390C for the reaction to take place and you don't get that in an engine anywhere but in the combustion chamber. All that really happens is that the PTFE particles in slick 50 block up your oil filter pores and thus lead to less filtration higher filter back pressures and less oil flow

    Ok, well it worked for me. It was purposely only left in for 3k miles. Definitely sorted my engine out. Have you used it yourself to ill-effect enda1?

    Also guys, look at the date on the flippin article!!! Its 1996, thats 11 years ago!!! Even if there were problems, I'm sure if they were that serious of issues, the product would not still be on sale or would have been changed!!

    Had an engine on a kawasaki 250 sieze after application of slick50 due to oil starvation.
    It hasn't changed its still a PTFE suspension for addition to engine oil, the only thing thats different is the claims they can now legally make. Have a search on the internet and see what the consenus is.
    Some reports show a reduction in friction some don't but most seem to report a loss in oil pressure due to clogged oil ways and filter pores where the solid PTFE settles and in the long term a loss in oil pressure is not worth any gains in power or reduction in friction

    Ok, fair enough, but is that not a bike? Different kettle of fish i would have thought. Did you have it in for long? It must be put in with a new filter also.

    It was 15 years ago engine siezed at 70 on the M6 on the way to Manchester. Managed to get the clutch in before the rear wheel locked up, not a pleasant experience.
    After that I started looking into the claims of slick 50 etc and I formed my own opinion.
    As for the engine it was still a four stroke engine so I don't think the difference is to great. I think the treatment was in for a couple of months.
    I just wouldn't put it in my car as the manufacturers have not been able to offer a convincing reason to use it

    i had a cavalier sri back in 1995 that siezed 400 miles after an aplication of slick 50 ! never used it since. The americans use seafoam engine and fuel system cleaner which is supposed to be good
