Hi guys, I have a MK2 VRs on 66,000 miles which is burning oil at quite high amounts.

 

Just a run down on the car:

 

2013 CTHE engine code 

completely stock 

66,000 miles

Oil breather pipe changed

fully serviced.

 

displaying low compression in cylinders 3&4 but completely fine in 1&2. Blue/grey smoke coming from exhaust mainly at Idle.

 

I’ve heard replacing the oil jets also helps but I don’t think this is my issue here, is it more likely to be valve seals or could it be piston rings at this low mileage?

 

Any advice on fixes or just general information would be helpful

 

H, welcome.

 

You have a VRS with lowish average annual mileage so hopefully those engine oil and filter changes (which are the bare minimum for annual engine "service") have been of a timely nature and better still in my opinion using better oil than VW dictate.  Even then you could still get and have the issues you have.

 

The compression figures for all cylinders and how the tests were done would be useful, did you do dry and wet tests.

 

Don't make any guesses or assumptions instead do tests and checks and check and test the results of those tests (check and test if possible any testing equipment before using).

 

If you have access to a scan tool a report and error codes from it might also be helpful - the scan tool needs to be VW appropriate and have the program for your model and year (or VIN) and that program be fully up to date before use on your car, also the car battery and if appropriate scan tool battery both need to be in a reasonable state of charge to avoid spurious results and readings.

 

If you don't get more and better replies here you would be better looking at the threads and posts about your engine in VRS and Fabia Mk2 forums and/or posting there.  I know there's quite a lot on the twin chargers and knowledge in the Mk2 forum. - https://www.briskoda.net/forums/forum/113-skoda-fabia-mk2-2007-2014/

 

Good luck.

Hi Nta16!

 

Yes so all the services have been at the correct time however the car only went 2000 miles between 2022-2024 but still serviced.

 

Currently using the Castro oil recommended for the engine, but I’ll definitely take a look to see if others seem to work better.

 

Cylinder 1- 125

cylinder 2- 135

cylinder 3- 80

cylinder 4 - 75

 

id like to point out the car did start misfiring but after changing the spark plugs and coil packs for uprated parts, this has stopped.

 

The car is booked in with a Skoda specialist on Tuesday so I’m hoping they have come across this issue before. At this point I’ll take anything but piston rings!!!

Head gasket leak between 3 and 4 seems like one possible explanation, given those numbers.

Resulting misfires running fuel down bore walls, spoiling sealing?

Breezy_pete, that was my first thought that it could be the head gasket but I’ve not lost any coolant, which I know is only one common symptom but it’s normally a tell tale sign of the head gasket being gone.

 

and I’m not sure why the misfires would then stop after changing the coils and spark plugs unless unrelated?

Nearest coolant channels through the gasket may be far enough from the breach to not leak into it.

Needs professional diagnosis I think really, since any major work on this engine type is going to involve a lot of hours of labour stripping stuff down, so going on a wild goose chase is likely to be costly.

Sorry, could not link, search the thread.   Some say worked.

I asked a Mod to move the thread to the Fabia Mk2 section.

@Ootohere you may already know this but in case not you can link to a post on the page if you want by getting your cursor (finger? stylus?) on the time of the post you want, just as an example your last post here. - https://www.briskoda.net/forums/topic/530580-skoda-fabia-vrs-mk2-2013-cthe-burning-oil/#findComment-5923481

 

 

Coolant loss is one one possible cause of HGF (head gasket failure) and I can tell you from experience that the signs are a lot more noticeable with hindsight, depending on the cause of HGF the sign(s) can easily be missed at the very start.  The misfires were possibly/probably the common plugs and/or coil pack issues particularly with the twin chargers I've seen or been told.

 

Misfires and starting difficulty used to also be signs but I assume the computers sort or get round those more now (I'm used to much older cars).

 

Very short RAC article - Head gasket guide – why does it fail and how can I tell? - https://www.rac.co.uk/drive/advice/car-maintenance/head-gasket-guide-why-does-it-fail-and-how-can-i-tell/

 

HTH.

 

When doing compression test put a little bit of oil in the cylinder before testing said cylinder if compression increases will be pistons/ rings if doesn’t increase could be head gasket as previously stated
