Hi,

I have a 2014 skoda octavia mk3 5e vrs 2.0 tdi i am experiencing high oil consumption i have read this could be the reason due to it being stuck open/closed pcv valve. 

I have read some new cars don't have a pcv. Does anybody know if my car has a pcv? 

 

 

Hi Dillaz 

 

any news with the high oil consumption? I’m having problems with my Skoda Octavia Vrs  using to much oil had put 1 litre in after 1200 miles.

That is about right for every V.A.G car I have ever owned around about 1l for every 1000 miles.

I think care needs to be drawn to identify the specific engine if it was a petrol in a mk3 it would almost certainly have a PCV or PCV / fine oil separator.  The mk3 EA888 gen 3 in vRS (petrol) does.  Diesels, so far as I am aware do not employ such a device.

I've read that said before but never with the 3 VAG group cars I've owned.  I'd be disappointed and concerned at 1L per 1000 miles. Even on fixed service regime that would be 2 x 5L oil to purchase and also burned through combustion chambers, valves, cat converter etc. That is not a good base level of consumption.

Is it worth changing the rocket cover where the Pcv  valve is?

It’s a Skoda octavia VRS 2015 diesel I was using 2.5 to 3 litres of oil between services and now it’s getting worse, was told it’s a sticking PCV valve that can burn oil more quickly.

I have 2 x Audi TT’s both petrol both needed 1l of oil every 1000-1200 miles.

 

My diesal VRs was needed 1l every 1000-1500 miles.

 

Also had a Golf GTI for a while needed 1l every 1000-1200 miles.

 

My brother has also had a few Audi TT’s all needed 1l every 1000-1200 miles. He also had an R8 which needed 1l every 1000 miles.

Is there No need to change the rocket cover with the PCV valve in it?? To see if that helps was told the pcv valve can stick of stay open 🤷‍♂️

What is your engine? From what you say it must be a petrol vRS?  The rocker cover gasket is a poured seal. It is a big job to get that rocker cover up supporting cam towers etc etc. Is the rocker cover leaking? They all weep a little? Is it accounting for your consumption? If not look elsewhere.  You could replace the PCV / FOS edit: (unit itself).

Yep. But it isn't right is it? In last 10 years,  I have had a mk5 golf twin charger. Used about 1l in 7k miles.  a Mk2 vRS petrol used about 0,5l to 1L in 8k miles and now a mk7 Golf R, I would estimate 1L in 6k miles. The oil light did go on at 3k miles after change but I only put about 5.2L in, so it was 0.5 below specified full fill. Oil burning is not good for petrol engines especially. Medium and long term longevity impacted. Why should an engine need to burn 1L in 1k miles? 

@Skully27 no i didnt change pcv valve from what mechanics say (vag specialists) it dosent have pcv valve only petrols do.

I have had my turbo checked no fault no smoke if it was engine related i.e pistons/rings i would see white/blue smoke no smoke at all. 

Had vag specialists look at the car and they dont seem to know what the issue is.

Seems like nobody at all knows which i find weird. Ive been following alot of these forums even the seat and vw forums same engine fr 184 and gtd since 2018 no solution in any forum to our oil consumption problem.

@Skully27 what year and mileage is your car? The oil consumption is only going to get worse as mileage increases ive seen my car consume 1l-5k now its on 138.5k miles 1l-650miles.

According to my cousin who has worked for V.A.G for 30 plus years it is normal.

It’s on 91k, year is 2015 and it’s a diesel. I was told the pcv is in the rocket cover and need to change the rocket as the as the pcv come in the complete unit. 

Rocker cover, not rocket, but yes, looks like it's built in. Probably the round bit just below where hose 32 attaches here:

That's where the membrane is. But that's not the whole PCV system. I changed the membrane ( the old one actually looked fine but since I got a replacement I changed it anyway) and still getting high oil consumption and quite a good amount of oil in the hose 32. 

 

Also, @Skully27, you might want to first check if there's any amount of oil in that hose ( 32 ).  Unclip the side that goes into the air intake pipe and check it.

Tbh, I'm not sure that cars equiped with cat/dpf would smoke at all.  I think it all gets trapped in there. I had my DPF cleaned due to it being stuffed and the guys told me that there was a lot of oilish deposit in it. 

 

I'm going to soon do a compression test to see if it's all fine and I would also recommend anyone with this problem to do it.  The engine is going to be worked on anyway sometime next year, since there are only 3 options left in the whole system that could lead to oil consumption: worn out piston (

),  piston rings or valve stem seals.

@BogdanB, Sure, not just the round bit.

Not in my experience at all and not if you want to have your car without major engine issues for longer than a few years......1L per 1000 miles is too much even if some cars do display that.

On a diesel it won't be a PCV which is why it is integrated and seemingly not available separately. It will probably just be a baffle or gauze screen or both won't it? (Edited: internal diaphragm only it appears. Seems you can get some non genuine aftermarket parts for the diaphragm...)

Refer post by @Alvis 18 January 2019 in thread linked.

 

It seems VW did not only make poor design and engineering of pistons and rings on Petrol EA888 also diesels as well..

My car dosent have dpf got deleted over a year ago no smoke still but high oil consumption. Compression is fine cars bang on just its just oil consumption.

None of my VAG group cars have ever used that much oil:

 

S3 1.8T never needed oil topping up between services.

 

A4 1.9 TDI never needed oil topping up between services.

 

2 x S4 4.2I never needed topping up between services.

 

RS4 4.2FSI never needed more than 1L after 5k miles even after 84k miles.

 

Octavia III 1.4FSI never needed topping up between services.

I had a VW Touran 2005 2.0TDi from brand new it used oil at around 1.0 litre every 1k and was told by dealer oh yes they do use oil like that- sold it after a year and only 10 years later am I trying a VAG engined car again- Skoda 1.4TSi which after a year has not needed a top up of the oil👍

I know this is a old thread but has anyone figured out the height oil consumption, car recently got new piston rings and valve stem seals and springs, got head gasket done when I was it it aswell and the mechanic says my turbo is good, are we missing something as still using a litre of oil every few weeks and a lot of blue/white smoke on start up
