Burning oil
Burning oil
Hello Everyone
Im maybe a little old to do this but here goes I have an 18 son that drives my wife mx3 now him being a typical tennager he drives it rought but ey it is a sporty little car. Anyways since he been driving the car its now falling apart.
First question im burning oil its realy bad in the morning when my wife first starts it to a point where shes ytelling me to get rid of it and get me the new rx8 now i dont want to spend the money on an rx8 so do i need to change the valve seals and how hard can it be ? If its easy anough where can i get a manual?
second question The engine light stays on when shes stoped at a light the engine rpm goes up and down as soon as she touches the break. we did a computer test nothing came up mazda told me its the exaust sensor and another mazda told me the o2 so I though i would ask the expert u kids with ur hats on backwards .
ty for the help

Your compression schould not vary more than 10% in all 4/6 cylinders. If one of your cylinders is much lower then all the others you most likley have either a leaking head gasket a leaking valve stem seal or pistonringsucancheck to see if you have a blown/ leaking head gasket by checking you coolent wich sould be either red or green. if its milky / brown or smells like gas you know its your head gasket. if all cylinders read low and one of them is much lower then youll know its your piston rings. you can uselly tell by how long the car smokes. If it only dose it when you first start the car then you know its not the head gasket or the piston rings. Usully if its your valve stem seals it will do most of the smoking when you first start the car then very little after that. When i did a compression on my mx (4 cly) they all read around 175 psi if all of your cylinders are less then 130 psi somthing isnt right. its most likly your the valve stem seals which isnt too hard of a job to do as long as you are fimilar with engine work. you can do it without taking the head off and will only take a few hours. good luck!
