Hi all, my ce been burning oil for a year now and i cant find out how...no signs of leaks at all...no high smoke visable only at start up i notice bluish black smoke from tail pipe but not constant...any help be good... i have many issues also have fuel gauge and fuel light problem but one at a time lol
cheers
 
What engine?
How many k’s?
How often do you service it?
How much oil is lost each service?
What oil do you use? (Brand/weight/type)

All this is important otherwise we’re just crystal balling it
 
apolagies......1.5 litre version...iv had the car for a year been serviced every 10000km,coming up on 294000 km on the clock...im topping it up nearly once a week with about 200ml roughly...my mechanic told me to use heavier oil 6 months ago he suggested penrite hpr 30...20w-60 and been using that since
 
Have you checked the rocker cover seal and spark plug seals?
Could be an issue
 
from what i could observe from rocker cover no signs of oil and the spark plugs are bone dry,pcv valve is also clean and working no signs of oil and the intake all clean no signs of oil sneaking through the intake...im kinda stumped only thing i can think of is piston ring seals or valve stem seals...for what i paid for it could spending more than what i paid lol hit a roo last week so im already down a head light and fuel sender issues!!
 
You won't always see the smoke but at 300k your rings and valve stem seals are most likely the problem. The catalytic converter will super heat the burning oil and you can't see the smoke. The other issue could be valve guides these wear and cause oil usage issues. Everything can be repaired but cost is always the problem.
 
Thanks for your help every one. Finances are not on my side at the moment looks like I’m up *poo* creek with no paddle but I’m glad I have better idea what I’m facing here. Thanks again. Now onto my fuel gauge issue :)
 
The common fault with the fuel gauge is the in tank sender which is accessed under the back seat base.
 
Yes. I red the threads on here regarding it. Changed it last weekend. Tank never registered below half. Got new one in thought success. Filled up. Stayed at 1/4. Damit. Pulled it out again thought float stuck. Of course one bolt thread stripped on cover. So gasket doesn’t seal fully n I’m getting mad migraines from fuel vaporous but always traveled no further then 520km to a tank then refueled. Never seen refuel light come on and not electrical smart do unsure how to test if that works. Travelling 260km a day and I got to 400km and my tank below 1/4 so I’m unsure if this sender even working correctly either. So I’m not having good luck lately sorry. .. side note when I do fill up never gotten more then 33litres into the tank and just Thursday gone I filled. Clicked off 3 times and my gauge only went up to just above 3/4
 
Valve stem seals are common on mitsubishi engines. An easy test is to let the car idle for about 5 minutes without touching the throttle. Then give it a full throttle hit and watch for smoke out the back. If it’s blue/grey/black and smells - 100% valve stem seals
 
as you can see this is plug for my fuel sender...is there a test i can do to test for low fuel light? when i had this off turned car ignition on and nothing showed so does that mean light doesnt work or do i have to bridge the plug somehow to test the low fuel light?

Swap a bulb in the cluster, say highbeam with the fuel light. Then confirm the fuel light bulb works in a different spot.

Buy a 5-10L jerry can and just run the car till it stalls lol. Thats what i did a long time ago to confirm it worked. After that one time though, the light came on just before the level hit zero, consistently.

You may find that your fuel tank is dented in around the area of the sender unit, and stops the float moving entirely. Just a guess. Electrical fault would cause a very different symptom
 
where is the actual low level fuel light on the dash i cant see it even when i a shine a torch on it?
