    Car Sat For A Week, Now Engine Makes Funny Noise (Media Included)

    So I went on vacation for eight days and my car sat at a friends house. While it was sitting there, the birds used it for target practice. Anyways now that I'm driving it again I notice a clicking noise comming from the engine. Hopefully this is something that one of you can figure out. I have a 1999 1.8t Variant with Tiptronic.

    *** PROBLEM FIXED ***
    Some of the crankshaft pulley bolts were loose. I tightened all the bolts down and it went away. One wouldn't come out. I'll have to deal with that later...

    Top end sounds dry. Something must have caked in an oil passage. Could be the chain tensioner.

    sounds like mine, heh.. i'm in the process of changing the oil pump [what the VW dealership diagnosed] ...then probably the cam chain tensioner [VW said nothing about that, but it's what everyone else is telling me]

    Wow, that sounds loud. Is it recommended to NOT run the engine like that until you get it fixed?

    I just had the dealership change the cam adjusters about six weeks ago under warranty. My CPO warranty has now expired (24 months.) The sound isn't really noticeable when the car is being driven. I can only notice it when it's standing still. I doubt it's this but my dip-stick is half broken. So what should I check out to figure out what this is? I'm assuming I should check out the chain tensioner?

    It sounds like it's closer to the back of the engine. That's why I included video along with the audio.

    Interesting, I realize my Passat is 5 years newer, but mine sat for 10 days straight last week while we were on vacation and she started up without hesitation yesterday morning.

    Did the noise subside after it had been running for awhile?

    While driving, there is no noise, except at idle.

    My diagnosis, admittedly based on too little information, is an internal cam seal leak, which permits oil to leave the CCA bath. Your CCA is becoming oil-starved at idle.

    Mine started to clatter occasionally on cold starts at the 14k mi mark. By 22k mi, shortly after I changed to synthetic oil (mere coincindence?), it was clattering consistently on hot idle.

    I still have this problem, but it has changed. It's not as loud anymore and is at its worst when the block is cold. Once the block warms up it isn't as bad. The noise actually goes away above 1200 RPM too. I just checked the oil and it is full.

    Your cam chain is rattling. When they replaced the CCA, did they replace the cam seals as well? Are you perhaps leaking oil out of the CCA gasket, due to poor installation? (If so, you should smell burning oil on hot idle.) The other possibility is partial blockage of the oil pump by coke / "sludge."

    I don't smell any oil. My records are in the process of being shipped so I don't know EXACTLY what they did. I do know that I have an extra set of CCA gaskets though. Any good way to check or flush sludge?

    This sounds really odd but when I am having this problem the noise goes away. But when that doesn't happen the noise is there.

    Replaced the cam chain tensioner: didn't do much
    Replaced the accessory belt tensioner: noise got better (is usually quieter and happens less often)
    I replaced my timing belt and associated accessory belts a little over a year ago (before the noise started in the first place.)

    This is what it STILL sounds like:

    Wow that sounds bad, STOP running it! It sounds like it's gotten worse. Anything that sounds like that isn't good and i'd take it to the dealer asap, it could cost a bit but in the end it will save you thousands.

    It's gotten better. I've also had an ASE Certified mechanic tell me it is NOT the engine, but something with the accessories or accessory belt. If I loosen the accessory belt tensioner (the one that I replaced) so that the accessory belt is loose, the noise goes away completely.

    Holy crap, I've just realized I've had this problem for a year. Before I tried to fix the problem, it didn't really get worse.

    I think it might be you rod bearings. I just fixed a stupid chrysler that had the exact same noise! Most mechanics will avoid telling you this because in order to truly check, you have to remove the oil pan and on the 1.8 it's a bitch!!! You have to drop the subframe and it is labor intensive so it's not pretty! I just did that to my 1.8 because the oil pump screen was clogged and it took me 2 hours just to drop the subframe!! Good luck!

    This is the same noise mine had when I bought it....

    I thought it was the lifters making noise from oil starvation, it ended up being the cam chain tensioner not getting enough oil pressure to pump it up. I ended up dropping the pan and cleaning the oil pick up screen. Noise is gone. I would check the oil pressure with an external gauge to determing actual oil pressure and go from there. Don't jump to conclusions, be methodical in your troubleshooting. Don't throw parts at it, it will get expensive.
