I’ve just replaced the crankcase breather pipe on my 1.8t Octavia vRS. I know it’s a weak link on the engine and have replaced it with a silicon jobbee.

However, the new hose is bigger than the previous rubber job and fouls on the plastic covers that I took off to access the engine. Looking at VAG forums (no, not those VAG forums – VW Audi Group, you filthy little rapscallion!) it seems the common thing to do is give the pipe a little trim to get it all to fit in nicely – I don’t really fancy doing that.

So, I haven’t replaced the covers, but it has got me wondering – do I need to? Other than muffle engine noise, what do they actually do? Does the engine *need* them on?

The engine cover acts as a thermal barrier between the main magneto-driven flange comparator and the electro-hydraulic sprocket pump.
If you remove it, you run the risk of spontaneous inflammation caused by the dry running of the viscous coupled exhaust fan.
Hope that clears things up?

Hmm. I wondered if that was the case…

Doesn’t the duel-sprocket alert sensor alert me to intense heat build-up prior to spontaneous combustion?

Why not put the right sized pipe on? Problem solved.

BS. Everyone knows it’s to prevent quasiparticles from entering the nominate subordinate taxon layer. Unless you’ve got a blue car.

Makes the engine bay look tidier, and sound insulation so it doesn’t sound like an agricultural machine.

If my car didn’t have one, they’d be nothing to rattle the dipstick out…

Where you involved in this?

OEM pipe is £40, rubber and splits. Aftermarket pipe is £25-30, silicon and is guaranteed.

I did wonder… 😉

It’s blue. 😀

It’s blue.

….to kill your lambda sensor in the long run.

EFA^^^^

Mine has some strategically placed foam under it which muffles some sound from the camshaft area. Definitely sounds a bit clackier without it.

‘underhood beautification’ i think is the word i heard at work, and nvh

Really? How come? My impression was that the engine should be as sealed as possible, therefore a sealed pipe is better than one with a split in it.

I freely admit to being a reasonable bike monkey, but am not a car mechanic in the slightest.

Blue??! Don’t risk that aftermarket junk. Better you just flush your diskombobulator and fit the standard rekombobulatornator kit.

Pretty much what I thought. 🙂

Aren’t they really expensive unless I buy from a German shop?

Yep. 😉

Yep.

Thought as much. 🙁

hasn’t anybody thought of the effect on the flux capacitor?

My peugeot had one all it did was fall off.

No. 😳

i refuse to believe this of a French car. 😉

NO WAY!!!! Did you contact Peugeot and tell them this? I expect they were sat around twiddling their thumbs for years just waiting for something to fall off of one of their cars. 😉

Mainly for noise suppression, check on construction and use regs as noise suppression is part of type approval for the car.

I was furious and sold it in disgust then bought a citroen to replace it. 😉

lol

Keeps the water out of the coil packs. Just make a little nitch in the edge of the cover for the pipe. Job done!

Ooooh I had a nitch once,had to use a special cream to clear it 😀

Cheers – I think that may be the way forward.
