    confused My EGR Sucks..........Air?!

    After reading a thread about 1.8 MAF and a post about leaking EGR i'm now certain my EGR is sucking air in. I sprayed it with carb cleaner while the engine was running and it had an instant effect on the idle and h can hear it hissing.
    This is most likely the reason my eml has been coming on all this time (almost a year) and the rough idle etc.
    Can I just replace the gasket(s) and clean it or do I have to get a new egr?
    Cheers

    there's quite a bit of rust around so hoping a new gasket will be enough.
    Does anyone have a part number for gasket for my 52 1.8 sxi?

    ON most of the 1.8's in the market if they have been back to the Dealer the EGR has had a blanking plate fitted and the ECU reprogrammed to by-pass it. This was done best of very high failure rate of this part and warranty codes, however most owners never know as this "mod" is done on the quiet, to check you have to remove the EGR valve.

    Took it off yesterday, no blanking plate. There was alot of black deposit on the gasket and thick solid soot in the pipe below. Do I need another gasket for the part between the egr and engine block so I can clean it?
    I fitted the new gasket and it still sucks! Where is the best/cheapest place to get a new egr? Or shall I blank it? If so do I need to get done by the stealers?
    Cheers bil

    No joy at my local scrap yards for an egr so i've used some holts gun gum around where its leaking/sucking air. Had a little drive and seems ok, no hiss. Still looking for a cheap egr or info on blanking and reprogramming...

    After using gun gum the car cut out the next day and wouldn't start. I removed the egr and it was wet in one pipe so I took off some gun gum and its find now.
    Is the EGR supposed to suck air from the engine bay? Or could it be that the value is stuck closed?
