1.8 TSI High oil consumption..

[maverick54]

Does anyone know if the 1.4 TSI is known to use a lot of oil also? I'm getting thru a fair bit myself and it appears to be going out the exhaust.

[Ootohere]

It has not been common with 1.4 TSI (Turbo) Euro 5 engines like it has with 1.4 TSI / TFSI Twincharger Engines.

 

How many miles has your engine done and when was it built?

[maverick54]

Car has done 58,000 miles and is a 2011 plate with a caxa engine if thats any help. First noticed the oil consumption problem about 8 months ago when the oil light came on. Checked and oil was low. Bought 5 Ltrs and a new filter and did an oil change. Checked last week and had to add a full litre. Car had only done about 1,500 miles during that period. No external leaks anywhere.

[Ootohere]

Looks like you have a problem sadly. But 1 litre in 1,500 miles is not horrific.

  Was that short journeys?

Is it 5w 30 Full Synthetic oil Long Life. VW 504 00 that you used?

If so then you could change for 5W 40 Full Synthetic VW 502 00  and see if the oil consumption drops any. 

[maverick54]

Yes all short journeys and it was 5w 30 Full Synthetic oil Long Life. VW 504 00.

Take it the problem is caused by the oil getting passed the rings and being burnt in the cylinders. Does the thicker oil help this problem a little?

[Ootohere]

Not a case of the viscosity, just not crap long life oil that can cause short life of 1.4tsi or even 1.8 / 2.0 tsi engines.

(Castrol / Quantum being nothing special as an instance. Well IMO)

Maybe, try 5w 40 FS and Tesco Momentum 99 and get the oil to operating temperature on a few occasions and give the engine an Italian tune up.

(Give Shell V-Power Nitro+ and its secret detergents a miss, maybe Momentum has detergents the same, maybe not.)

 

This was the Twincharger problems including Bore Wash but it can be similar on non twincharger TSI's.

Okay so about 3weeks ago i had the dealer start an oil consumption test.

Today i "finished" the test and got the results.

1,1liter of oil in 1000km.

The car has been scheduled for new pistons and rods early december..

 

However im curious why they are replacing the rods?

Does anyone know why they do that?

The rods have lubrication ducts for the piston bolt. And where the lining of the piston pin is worn, oil will spray too much against the piston and the piston will bathing in oil. It should be honorable to change these lining? Can you check the old ones? It is not always they are worn.?

 

Else the crank house ventilation can be to big.

Updating again. Having paid a different dealer (Marshall's Oxford) some £250 for an oil consumption test, I now have formal opinion to back up what I already know... I'm using too much oil. One litre every 400 miles, The 5W40 used in the test didn't seem to make any difference to the consumption figures.

Interestingly I've been told that next stage (after measuring timing chain) could involve rebuilding engine (piston rods, etc) and this could cost me up to ~£3K. This is far less than the near £5K for an engine replacement I'd been told elsewhere.

Any views on whether it is worthwhile approaching Skoda UK for goodwill? Any hints on the approach to take? On one hand my car is getting on (59 plate). On the other hand it's not yet done 60K miles. They wouldn't talk to me until a dealer had backed up my own consumption figures.

@silver1011 I'll update the main engine thread once I've got a conclusion to my own saga.

[Sarge]

The age rather than the mileage is what is likely to influence Skoda uk. Previous experience in recent times indicates that anything over 5 years old and they don't want to know. But I would pursue it just in case....

[silver1011]

Skoda UK are far less generous now on goodwill outside of warranty than they used to be. They are a huge success story in the UK so our loyalty isn't worth as much to them as it once used to be. As a result as per Sarge, the 5 year limit is more strictly adhered to.

 

However that shouldn't put you off. Skoda UK are more than familiar with this issue, it is impossible for them to deny it isn't an issue on this engine. Be firm but fair, pleading poverty has helped me in the past. Your Skoda service history and the advice you've already received from a franchised Skoda dealer will stand in your favour.

 

Contact Skoda UK using the link below and ask them to open a case.

If they are properly rebuilding the engine, £3k is probably almost palatable. A new engine is more certain, but unpalatable at £5k. Presumably if they find more than pistons / rings / rods / bearings and timing chain kit you are up for more £££.

 

You can try a wrecked car donor engine but unless it has later revision internals it could have exactly the same problem you are experiencing or timing chain tensioner risk. You need to have such an engine fitted by someone, Skoda dealer won't do it and even if there was a limited warranty on the used item,  you will have paid for fitting / removal......

 

There are other engine remanufacturuers who advertise new reconditioned engines from about £2k mark for these models but I have no idea of their quality, service or the substance of their warranties.  There was a thread where someone found what sounded like a reliable rebuilder and the cost was ball park £3k mark from memory. Search through the threads and see if you can uncover it.  They would only recommend doing the piston and ring and conrod replacement. Rings alone won't fix the issue.

 

Some rebuilders you would have to ship the engine and get your own garage to fit the engine. More difficult logistics and not easy decisions.

[TheClient]

There are heaps and heaps of threads on 1.8 TSI oil consumption and lots of information. But relatively few with feedback and experience on engine rebuilds. Dealers tend to replace the engine, at great cost, as you know probably due to the very high labour rates, which make rebuild work uneconomic.  

 

This is the thread I was thinking of. Halesowen Engines sound knowledgeable. They strongly advised against the ring replacement in this thread but the poster accepted the risks.. They are west midlands so maybe not a million miles from you.

 

DAL jones Automotive comes up in google searches and quoted prices appear low, Maybe too low. No feedback I can recall reading.  

 

Either way, I haven't used either of them but you could PM the poster who used Halesowen. Doesn't necessarily look cheaper though, depending on how "fixed" the dealer quote really  is.....

[matkinson]

Cheers for all the advice. I think my next step hinges on whether I can persuade Skoda to contribute to my repair. I'll contact Skoda UK again. I'll update here once I get a response.

[matkinson]

Bah, Skoda UK won't provide any goodwill, based on the age of the car. My gamble of paying for an official oil consumption test to tell me what I already knew hasn't worked out :-(

I need the car for the next month. I now have to decide whether to shell out the £3K and hope that's sufficient or shift the car "as seen", which goes somewhat against my ethics.

[Lachy48]

Hi i own a 2010 skoda Octavia wagon 118 TSI which has done 128,000km and I am currently burning 1/L of oil within 400km!!! This is absolutely ridiculous!

I have spoken to a number of mechanics who have said i either have to get an engine rebuild being $7000-$8000 or a new engine from skoda for $10000 Neue to my piston rulings being shot. 

I have also found a vw Passat may 2012 118 TSI with the same engine code CDAA which has done 71,000 km for $4500 including fitting. 

I have also been told putting in a Positive crankcase system will alleviate my excessive oil consumption problem significantly.

 

Will a PVC work?

Is the piston rings in the Vw Passat different from my car?

or should I just get my engine rebuilt or a new engine installed?

[TheClient]

The car should already have a pcv system. Are you saying replace the pcv / oil separator? It could help but seriously doubt that is the primary issue.

 

Vw engines use very similar parts and went through piston / ring and  tensioner changes at pretty much same times. A 2012 or later engine could be worth a gamble. You need to find out exactly when tye piston and ring changes would if entered production. Along with latest tensioner.  

 

I'm not sure where you are but a rebuild from a reliable remanufacturer who can install revised piston rings to help alleviate problen is probably surest thing. In uk it would probably be over £3k...

How long have you owned the car?  Has this happened suddenly; has it always used this amount or has it crept up over time?

 

1l/400km is probably a failure of the glue that bonds the internal plastic part of the PCV labyrinth to the metal rocker cover.  I'd suggest you have the rocker cover removed and the bond between these parts inspected before venturing to an engine rebuild. Note that some of the bonded parts can't be seen, so a visual check might not be totally satisfactory.  You may as well change the external part of the the PCV.  It's a $100 part off ebay.

 

I'm assuming you have spoken to Independent VW specialists and not some random workshop?

 

On what basis (besides oil usage) are they saying the rings are shot and quoting an engine rebuild?

I know many garages (Especially Australian workshops) lack diagnosis skills but has anyone done a wet & dry compression tests and a leak down test?  Has anyone checked the turbo outlet pipe for significant amounts of oil?  I'm assuming there are no significant leaks.

 

What brand / viscosity of oil are you using?  I assume being in AUS you get a service every 12m/15000km (whichever comes first).

If usage was less extreme (1L/1000km) I'd recommend a 5w-40 or 10w-40 502.00 spec oil but in this case, there's definitely a mechanical issue.

 

Before you go throwing a stack of money at the engine you need to consider that the whole car is only worth ~$7k and you have the rubbish  dry clutch DSG7 and also the bad timing chain tensioner.  You might be better off adding 500ml of engine honey to slow down the oil usage and move the car on rather than throwing more money at it.

[Stratguy]

Hi everyone, new here. 

My story is not unusual compared to all the other ones above. Practically had to throw away my crap Audi A6 since it was wrecking my economy completely. Bought my current car, Skoda Superb 2010 1.8 TSI. Burns 1L of oil every 400km. Have tried an additive, RVS. Improved it a little bit. Going to try Wynns engine flush as well. Getting desperate. Really hate VAG. How is it possible that they can get away with this  fraudulent behavior towards us byers? They seem to think we`re made of money. Changing the engine as if we`re talking about spark plugs. 

Have a question. My car runs fine, except for the oil burning. But. Sometimes after driving for a while and slowing down, changing gear, it is like the engine ”burps” or coughs for a second and out comes a puff of smoke. No exessive smoke otherwise or leaks. Don`t know much about engines but I keep thinking that there`s something with the crank case ventilation, too much oil comes up through there and gets in to the pistons and it gets too much for the engine, hence it coughs. PCV valve? Could this be a contributing factor to the ridiculous oil consumption? Ready to try a few things before taking out the engine. 

Also. Can the pistons be taken out from underneath without lifting out the engine itself? Read somewhere it is possible. 

Questions from a desperate Swede. 

[Nuclear_Jules]

Sounds similar to mine you do see a puff of smoke on downchages sometimes and definitely when you accelerate hard and change up. Skoda dealer have done compression tests and say it needs new pistons and con rods, they are changing the cam chain and tensioner too.

[Stratguy]

You`re not under warranty I suppose... Should be a class act...

Wrong spelling

[Nuclear_Jules]

It’s a 2011 car being sorted by the dealer as I bought it secondhand 8 weeks ago. I’m not picking up the bill they have already put a new turbo on it.

Sounds like worn valve stems/seals, draws oil in on the overrun, probably fouling plugs too. Puff of blue smoke when opening up throttle again.

Short term solution: use a thicker grade of oil

[Stratguy]

Sort of good news Those seals can be changed without taking out the engine. Worth trying right?

[Stratguy]

Anyone ever heard of someone who got the oilburning problem sorted without a piston etc change, like only valve seals and maybe something else? What I mean is without taking out/changing the engine?
