The only thing that let's fuel into oil is when your cooling system malfunctions it will make the D4 pump seal to be hard and cause it to crack.making the car run out of fuel can cause the D4 to malfunction.do not add injector cleaner in to your petrol on car with D4 pumps it opens 4th he nozzles so they end up dribbling that produces a black smoke
It seems you haven't been taking enough care on your car up to the point the whole cylinder head is worn out leaking oil from the inlet means both the valve stamp seals,valveguides ,oil scrapper rings valves and timing belt worn out. The timing jumped making the piston hit the valves damaging the guides and seals, oil started to come into cylinder and during comp%ssion it is pushed through the valves to the inlet until it damanges the throttle body.the D4 pump is also faulty, low pressure if the car can't rev. Better do cylinder head service and buy another D4 pump before condemning the throttlebody
what year.?
what are all the symptoms.?
what country?
does this car, (no year) have a scanner port so you can scan it and
see if the injector brain is showing DTC errors.
no year car, so how can we help you, ?
The D4 pump has a seal and it cooled by the fan which it faces so if your car is not putting fans in the seal collapses and starts to drop large quantities of petrol into oil you can check every morning your oil level to notice the defect
