So I noticed a few drops of oil on the drive today. Turns out I have a large oil leak that has been going on for some time. It appears to be leaking from the gap between the gearbox and the drivers side driveshaft. The oil is a mix of old baked on crap and brand new still golden. What I don't understand is why it appears to be coming from the gearbox, surely the engine and gearbox don't share an oil circuit? or could it be the leak is dropping directly on that spot from above? anyone have any ideas?. I have no doubt that the engine is burning oil, but this leak has to be a big contributor to the consumption. I'm going to deal with the leak and see what happens to the consumption before I do anything else. Edit: actually it's probably the rear main seal...

It has always burned oil but it wasn't enough to concern me, the previous owner has posted here about oil issues when he had the car too. I went from 5w40 to 5w40 and things improved slightly. I started to really pay attention to the usage and as of last summer it was about 0.7L/1000km. Then all of a sudden it jumped to around 1.0L/1000km a few weeks ago. I can accept 0.7L/1000km because it's done 67k and doesn't get the easiest life but 1.0L/1000km is taking the p***.

Thanks for the info, I wanted to see what they actually changed or re-routed because I have not seen any clear pictures of the fix. I will just do the fix myself once I can see how they changed the configuration. Currently at 1L per 1000km and now using a pcv restrictor for a couple of weeks to see if that does anything.
-
I have now ruled out valve stem seals, and I'm actually pretty sure it's all down to the breather / pcv. I was sure my engine was toasted but I have had no loss of performance (except the fact that I put the car back to standard until I resolve the issue). Next week I am going to try a restrictor on the bigger pipe that goes to the intake, theory being that the crankcase is actually breathing too much, like a regular pcv valve stuck open. Can someone who has had the "breather mod" fitted by a dealer post some pictures please? so I can see what they altered? thanks.

Fabia vrs oil cap opening blocked

I have switched myself to 5w40 and to be honest consumption has actually increased. -
So far no progress, still using oil at the same rate. So I have ruled out the PCV system pressurising the oil return line problem as the cause. I'm putting it back to stock configuration while I figure out what to do next. Possible avenues to explore: 1. Oil seperator doing lousy job and PCV just throwing loads of oily vapour through. 2. Valve stem seals leaking on 3 cylinders. 3. Damaged oil control rings, but good compression rings.

Does yours have the breather mod? or is that just a normal CTHE? -
No breather mod, from the photos I have seen of it they seem to have a slightly different layout to mine maybe they are CTHE engines?. I now have the boost solenoid venting to atmosphere to reduce throughput between the PCV and intake when on boost. Also I have a larger pipe coming tomorrow for the breather to see if that helps. I will check the oil again on Saturday to see if anything has helped or if I am barking up the wrong tree.
-
Update: I suspect the PCV has become gunged up and is not evacuating enough blow by when on boost. In theory this will be pressurising the crankcase pushing oil past the turbo oil seals. I'm thinking cylinder 4 is clean because it is furthest from the throttle body. First experiment, I have deleted the one way valve on the breather inlet. In theory this will work the same way on idle but provide a second route for blow by gas to vent on boost. Currently looking for a replacement PCV valve, also want to try a breather filter vented to atmosphere with the other pipes blocked to see what effect it has on consumption. I will update in a few days with any changes, last oil consumption check was 0.93L/1000km.

Hi Guys My engine suddenly started consuming lots of oil last week. My first thought was a piston failure so I bought a compression testing kit to verify. Just done the test and the compression is bang on (145-147) psi on all cylinders. However spark plugs 1-3 are all caked in oil (and the piston crowns look wet) but cylinder 4 has a perfect looking plug and a dry piston crown. My second suspect is a bad PCV but I would have thought all cylinders should be equally as oily on that case. Could be valve stem seals but I don't see 3 going bad all at the same time, anyone have any ideas?

A spark is a spark, I doubt the R8 coils would offer you any benefit over a set of standard coils except looking cool. -

you need a feeler gauge or gapping tool, I have tried gaps between 0.8 and 0.4mm and found that the car idles better with a bigger gap but misfires less under load with a smaller gap.
