Gentlemen( and ladies) I have a query and I hope you can advise me. Whilst changing the engine coolant sensor, I managed to snap the Plastic pipe off of the 3 way rocker breather thing on top of the engine (afn) 1.9tdi. How will this effect the general running of the car other than oil laden vapour escaping? I have done an evry, blanked the egr, put cooker cleaner in the turbo etc so am fairly clued up. I am just not too sure if this is a pressure system which will not appreciate leaking to atmosphere. You comments are welcome.
