My Toyota nadia d4 is mixing fuel nd oil.but the level of oil is not rising its actualy getting low .if u touch it its light and smells of petrol..By the exhaust the black smoke is wet..what must i...

The high pressure fuel pump is leaking fuel past its seals into the engine oil.

The hp fuel pump is located on the valve cover.

The oil level will not rise because when the oil is contaminated with fuel, it's viscosity is affected, and it will make the engine burn more oil.

You will need to replace the High Pressure Fuel Pump, drain and fush oil and replace oil filter.

What causes oil and petrol to mix in toyota nadia D4. How can i prevent the pump from failing. Fuel consuption too high

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 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

Good Day, I was looking at a 1998 Toyota Ardeo Vista. It has done 112,000K but was surprised to hear the engine making a different noise. The mechanic said that was normal for the ardeo d4 vista engines...

if its making any sort of metalic knocking noise then leave well alone ,could have been run out of oil or coolant hence funny noise and someone is trying to pass it on as it blow up before long and they dont want to get stuck with paying out on it

I am hearing a noise in the engine of my 1999 toyota vista ardeo,what could possibly be the cause? Does the d4 engines carries valve lifters?

Hi there, the noise you might be referring to which sounds similar to a typewriter may be the cam gear for the VVT found at the intake. If it is louder than when you got this it may need check up. Changes in the O rings or may need replacement if you also notice a decrease in power at certain revs. Not all sounds however may not be the case. High pitch sounds may be because of timing belts or metal to metal contact which may need lubrication. As for valve lifters, the one that you have does not have any.
