Ihave a 1.9 tdi, and there is oil leaking from the side holes of the EGR valve, and also the at the bottom junction. Does anyone have any experience with this problem, Pa TDI. 1999.5 Jetta TDI 5 speed. Apr 7, 2011. #7. 85_305 said: Diesels have blowby. Not enough blowby to blow the oil fill cap against the hood when its just sitting on the valve cover. my 5.9litre cummins diesel with 330,000 miles dont have even a quarter of the blow by as this tiny 1.9litre. 8. Minehad a good little leak to it. I pulled it, thoroughly brake cleaned the valve cover, and cleaned the mating surface on the head with a rag soaked in brake clean. After all was clean and dry, I used ford grey silicone (was designed for the 7.3 powerstroke. They dont have an oil pan gasket, the grey silicone is all.

You can try chemicals like brake cleaner or soak in Mr Muscle oven cleaner, or mechanical clean scraping the gunk with a Oilseepage is normal on any turbo so if you remove the hose it is normal to find some oil in the lines, now knowing this back to the EGR valve, if you see oil Ihad one of these engines in a Mk 1 Fabia, using Millers oil and Millers fuel additive, and catalyst-core removed at about 60,000 miles, also had the engine re-mapped from 75bhp (actual 79 on the rolling-road) up to 99.9bhp, was getting 76.5mpg all summer (flattish area, taking it gently, using the extra torque) and got to 850miles before the EGRand throttle body cleaning Skoda Fabia 1.9 tdi AXR | Fix My Car Garage. ExhaustGas Recirculation is a system designed primarily to reduce nitrogen oxide emissions from internal combustion engines, but a quality EGR system properly fitted can also increase engine efficiency. EGR is a required feature on most modern internal combustion engines. EGR works by recirculating a portion of an engine’s exhaust stream TodayI put in the fuel filter 8ml Toralin UV dye and ran the car for 60 seconds at 2000-3000rmp. Opened up the valve cover and only saw a faint sign of UV dye on 2005Touran 1.9 TDi, Diesel leaking into engine oil & starting issues w/75% fuel. So I replaced the Tandem pump last week and I cleaned out the EGR and butterfly valve (very dirty). I've read that the Tandem pump might be the issue for the fuel/oil coming together, might it also be losing it's vacuum and causing the fuel to loose 3K7yH.
