Hello. Mechanic found a little oil in the engine when replacing the spark plugs. I topped up twice per liter of oil between oil services. the first time after 11,000 km and the second time after 6,000 km.
Cqr had 128,000 et first oil leakage.
Car drive normally and no any sings of external oil.
leakage.
What should i do? Can i couse a biger faliure?
Any comment is welcome.

Kind regards

If it's not leaking the oil then it's burning it. I'd get a compression check first to be sure the rings are OK.

Thank you. The mechanic suspected a valve seal but that further diagnosis would be needed to determine for sure. I will check your recommendation also

[Blue90]

What rings and what cheking the compression mean?
Sorry i totaly inexpert

[Billfitz]

You don't need to know. Your mechanic does. But it doesn't hurt to know this, because when some mechanics take you for a neophyte they really take you.

Thanks for the video. Very nice video and the you tube profile. So your would start with piston rings cheking?
The car was chip tunned from previous owner 1 year.
The mechanic who find a little bit oil in the engine replacing the spark plugs he said he find only few drops. Should i contact the same mechanic and ask where exactly he find the oil? Should i start with diagnosis asap? Thanks for your time

So mechanic noticed oil outside of the engine (your thread title says internal leak)? Perhaps as spark plugs were changed the oil he saw was either from valve cover gasket or the oil filter housing gasket. But yes, confirm from the mechanic more details about his finding.

In most cases if the leakage is so bad that you need to add more oil then you will also get drops under the car, or at least traces of oil at the bottom of the car. Usually when you need to add more oil it is then consuming it internally (i.e. it comes out of the tailpipe as smoke) rather than leaking it outside of the engine. In that case usual suspects are for example piston rings, valve seals, turbocharger and crankcase ventilation (PCV valve).

Adding oil after 6000 km does not indicate anything very alarming but you should keep an eye on the consumption if it gets worse.

I m not sure in this now. I didnt said outside of the engine. Mechanic said inside the engine, and later with some extra explanation in the email they talking about my situation with internal oil leakage.
What you mean exactly buy this outside the engine with my thread title inside the engine?
I will check with mechanic where he found the oil exactly. I m liittle bit worry only because they told that there should be no oil in the place where they found it.
Thanks for advices, i will keep checking

I meant that if all he did was change spark plugs, I assume the oil that he saw then must be leaking so that it is visible outside of the engine. To me that means the leak is external, but this is just semantics as the oil leaks to the outside from the internals of the engine

In any case ask him what he thinks needs to be repaired. We can then speculate here that does his diagnosis sound valid.

During a spark plug change, you can see inside the cylinder. It is possible the mechanic saw oil on the piston, which would hint at leaky valve stem seals.

[Blue90]

I thought you mean that . If he find the oil in the spark plugs hole than i dont know is that mean inside or outside the engine.
I'm not sure what the mechanic did the car had a regular big service. I told him to check oil leakage because I topping oil twice 1L 2 times, between oil service and then they told me as a result of everything that when changing the spark plugs they found a little oil oil supposedly a few drops and they told me that I don't need to worry about it?! Mechanics said that he suspected a valve seal but that further diagnosis would be needed to determine for sure

[Blue90]

he suspected a valve seal yes.

Thanks everyone for reply ��

Small update.
Garage noticed some oil on spark plugs.. A bit of oil may have spilled when topping up the engine. ,
I also hear the oil could be from the filler cap.

One garage said maybe nothing to worry about , another said urgent, 3rd garage said sell the car😁

I will definitely visit more experts around. I will do compression check of the rings and another checking.
I m starting to think its nothing, car drives really good.
Just maybe i notice little bit shaking in parking mode,really gentle, just sometimes and rarely

If it is not spillage then most likely it is leakage from the part of the valve cover gasket that seals the holes of the spark plugs.

Thanks, i will keep in mind that also

[Blue90]

What mean if the oil burning?
