Breather pipe the narrow pipe at the top of the engine has broken where the air filter is has broken it goes down the back of engine to where i carnt seem to locate where goes .

breather clogged replace

If you mean the breather is throwing out oil then you have a problem as this is caused by back pressure within the engine ,cause worn piston rings

weird i must say ,check for a breather pipe from the lower engine area to the top or the air filter area ,sorry iam not a hyundai dealer fitter so i wouldnt know the layout but i suspect a blocked breather pipe somewhere

Problem could be either to much air OR to much fuel in inlet manifold
If you have a pipe broken or come off the inlet manifold from either a breather from the engine that could cause it, or a problem from the fuel tank such as a fuel filter on the line from the tank to the engine,or Air Filter needs cleaning etc, or even a air leak in the Inlet manifold gasket.

Does the engine breather pipe have a pcv valve on it?
How much oil do you have to add? in a week? In a month?

follow the line backwards down to the block and clean the breather(if fitted) this is not an oil leak, the pipe is there to **** up the engine pressure when decelerating.........the air filter should be changed every 20 thousand miles/2 years.....

spray some carb cleaner down the breather pipe the carb could be clogged up so it is not opening properly and choking the engine or flush out your feul they may be dirty and your not getting enough fuel through when you need it or your air intake senser might need changing cus if your air/fuel mix is wrong your engine will stall

Hi Tom, Sounds like your car may be running in limp mode. might be worth a diagnostic check and clear any codes and get them reset. Hope this works.

If you are saying when you remove the air duct hose from the front of the car to the top of the engine, then look for a plugged air duct or filter that is starving the engine of air when all is assembled properly.

If youre looking at the engine, the oil filter is on the right side of the engine, you have to get to it from the bottom of the van. The battery im not too sure off the top of my head, it should be on the right side as well, possibly tucked away in the back corner.
