Hi there. My 1995 accent(1.5 feul injection) makes a noise like when its low on oil but it isnt , the engin was redcond a few months ago. And if there is any tips on how to stop the leak on the crank oil seal it will be help full i replace it almost every 2 months.Thanx

check for fuel leak at the pump. pull and fit new tips to the injectors. Have the injection timing checked by an accredited diesel shop ( same one that is replacing the injector tips)

very possible
talk to a range rover dealer to get the information about a low oil sensor that has to be reset

You might check the pulleys that the serpentine belt runs on. Make sure all are free wheeling and not loose or rough or make noise. You would need to remove the belt to check them.

It is time that the car had been for a check up on the maintenence schedule. It is necesary to check the oil, the oil filter, fuel filter and the feul settings.
If these are clogged the performance will be reduced and the engine will underperform.
Please have the oil replaced if clogged as the error indicates.

The ticking noise, if related to your engine would get faster and slower "with" your engines' RPM. If it isn't matching the engine then I would be wary of a possible wheel bearing getting ready to take you for the U-Turn of your life! Try pulling (very hard) on the top of the tire closest to that area to see if you can feel looseness or "play" ...cuz there shouldn't be any "play" or noises at all.

excess use of oil is caused by only one thing a badly worn engine or one thats been hammered by a previous owner like a rental car or sales rep ,worn rings and valve guides are the main reasons for oil use ,ps whats a quart ?? whats that in proper measurements like how many litres and do not forget the trunk is called a boot .

is it low on oil? if so it could be an internal oil leak (wouldn't be able to see) or external but you didn't say anything about that... if level is good replave the oil pressure sensor

You might have a bad hydraulic valve lifter (assuming this engine has them)... you could try an aftermarket product designed to unstick valve lifters.... any auto parts store carries them.

have you ever had the injectors checked. if not try runing some fuel injection cleaners through it and see if that works

noise is caused by lack of oil to lifters, or worn timeing chain. if noise is from lifters it should go away wit proper oil level, if still there needs timeing chain.
