Hello!

 

Around 2-3 weeks ago I fitted a forge BOV adapter, doing the usual under-hood checks and noticed a slight oil residue coming out the holes of the BOV adapter and a slight covering of oil on the black pipe below as you can also see in the picture.

 

So... my question is, is this normal or not.   I’m not very mechanically minded haha.

 

any info is much appreciated.

 

skoda Octavia - 1.4 tsi 122bhp CAXA engine.

Not normal but not unusual either. Doesn't appear to be a great deal. Changing the fine oil separator / pcv on my fl 2.0 tsi helped reduce oil leakage there. Not sure of what is fitted to the 1.2tsi, presumably something related to blow by gasses. 

Sorry, can't help on the oil vapour, but...

 

...a blow-off valve on a 1.4 TSI Octavia!?

 

😂

Its totally normal to have a bit of oil in the intake system, if you are venting this air to atmosphere its pretty obvious there is going to be traces of oil.

Not everyone can afford the vrs. Just harmless fun, gotta work with what you got 😂 

@Octavia122

What gain is there other than a bit of visible oil?

A whoosh of air when you lift off the accelerator, replicating a turbo waste gate.

Each to their own, if we all liked the same stuff then the world would be a very boring place.

 

A MkII vRS can be had for very little money,  I think I'd rather have an older vRS than a newer 1.4 TSI that's all show and no go.

 

I can say the 1.4 TSI is a peach of an engine, ironically one of its appeals is how quiet it is 😂

I do agree. But the engine has been so reliable and has a great service history so I’d hate to get the vrs with higher mileage and get A load of expensive problems haha. Although I do understand they are pretty well built engines.

you mean “replicating a dump valve“ 🤣 the wastegate is part of most turbos, noise or not, and has nothing to do with releasing excess boost pressure.

 

im guessing the valve is some sort of hybrid recirc/bov? If so I’d agree that some oil will be normal due to the oil in the intercooler piping.

Yep, dump valve, both terms generally attributable to the younger generation.

 

Listening to this Leon, it reminded me of a truck's air brakes, or the doors opening on a bus...

 

  

I asked what you gain not what you get.

I know you get a noise with no gain. Unless you like stylee over function.

Some information on wastegates and there function if your not aware.

Whether or not it’s attributable to younger generation it’s still wrong 😂

It’ll gain nothing except noise, but if that’s what floats your boat then good on you, I love a car to be a bit antisocial, my S4 blows flames out the exhaust, is it necessary? No, is it fun and do I enjoy the theatre of it all? Hell yea 😂

Blowing flames out of the exhaust isn't necessarily antisocial, waking people up could be.

Yes, especially so, if this adaptor allows the DV to vent to atmosphere instead of recirc in the turbo, as is the standard arrangement.
