    MALONE 1.5 EGR DELETE
    Hello All,

    I started hearing what sounded like an exhaust leak at low rmps/taking off, after several hours the "emissions workshop" light came on. I hooked it up the the VCDS and get the following reading. This car has 196,000 miles, with its second timing belt being installed about 10k miles ago. The Cam has never been replaced. The sounds goes through the the whole rev band. Limits at 5k. no black soot at exhaust tailpipe. I did lift the car up and couldn't find an exhaust leek at the back of the manifold. sounds more like the top back of the engine. Can I keep driving the car? Is it the MAF? or is the cam or followers worn out? any suggestions are welcome.

    Maybe egr related? I think if the egr is playing up or there's a leak in maybe the pipe from the exhaust manifold it can throw the maf out.

    Not sure if a bad maf could also throw the egr out though and cause the noise.

    Might be worth disconnecting the maf and seeing if the noise changes.

    Good point. I just replaced the valve cover gasket, and it has stopped the seeping oil to the back of the motor. This may have caused the gasket to fail, but I have not diagnosed it either. It's hard to observe as the egr is in the way. I will try to get a camera behind there tomorrow.
