this is more than likely on here somewhere fuel leaking white smoke and where the injectors are it's flooded with fuel car runs fine tho new injectors about 8 months back
First off mop it all up and clean, then remove the leak back T pieces and double check them, also make sure that the collars are tight and the right way round, were new copper washers used when the injectors were replaced? check leak back hoses in fact change the plastic leak back T joints for brass ones and new hoses link below. https://www.ebay.co.uk/itm/LAND-ROV...ECTOR-KIT-3-x-180-1-x-90-1m-Pipe/281404361492
