    Default unuseal egr valve removal related question ??!!??

    posted thos elsewhere but thot id get better answers on its own .

    This might be a stupid question as iv not looked in to it at all to see if its even possible just a thot that poped in my head last night , but if you where to blank the egr port on the inlet manifold side and leave the feed pipe open to atmosphere (relocating to under car and removing egr completely) would this act like a cat bypass or "screemer pipe " as iv heard them called ? Answers please as its got me wondering n Im worried that the next time iv have some free time I'm gona try it out n make a massive **** up , and before anyone asked iv not even looked to see if the feed pipe is before or after the turbo , if its before then obv this won't work but if anyone knows it will satisfi my curiosity , cheers

    Highly inadvisable, the EGR system works by opening a valve allowing the high pressure in the exhaust manifold to drop across the EGR pipe, causing a flow of Exhaust gases from the exhaust manifold to the inlet manifold. What you are proposing to to do remove this valve, hence the pressure will always escape, causing the turbo to lose pressure all the time resulting in rubbish drivability.

    For your plan the EGR valve itself would need to be connected. But it's all pointless as what you are doing is still technically blanking the valve off as far as the inlet manifold is concerned. Even at that you still have the gases - that now have no purpose whatsoever - flowing out still giving you the issues the valve normally give - leaking of turbo pressure. If that valve still doesn't close properly for what ever reason then you will still get bad performance.

    As said with leave as working or blank and get it remapped off.

    Can't argue with any of that - apart from the "leave as working" bit

    Lol Yeah right after I posted that I figured the feed pipe would come off the exhaust manifold so is before the turbo so would not work and just cause the same problem as the egr sticking open only worse , maybe I should have just asked if it was post or pre turbo , ah well that's that out my head now lol , I made reducing plates and cleaned my egr the other day that worked well but still had the problem just not as bad so removed the motor part of the egr yesterday and that's sorted the loss of power and drives much better now but the light is on now and can't afford a remap just now so will have to make do and hope no new problems are masked

    Thought I would sound fair. Can't say I miss it.
