Need help! 034 103 553 D

[MariuS6]

Hello, I would like if someone could help me with the oil deflectors from the cylinder head, I have searched on different sites, ebay, etc, but no longer available. 034 103 553 D. Is there only one or do I need two?

If your talking about an 20V turbo engine there is one that fits directly under the oil filer cap, so you only need one.

And to be honest that's far from essential, I tend to remove them if they're old as they go brittle and end up in bits in the head and sump.

During the restoration of the engine it was dropped and broke into a hundred pieces. I wonder if it has any negative impact in the long term and if, somehow, someone can help me with this part, or a link where it can be purchased. yes, it comes from a urs6 20v. thanks!

Delete it. Its only purpose is to prevent oil splashing out if you remove the oil filler cap when the engine is running. They become brittle with age and fall apart.

I thought it had a role in maintaining lubrication on the camshafts, that's why I asked, although there are two and I don't see the role of the second one, if the role of the one under the filler cap is just to prevent splashing.

Exactly that. It's basically a useless time bomb.

Unlike the one's on some later Audi engines it's serves no useful mechanical function whatsoever.

Did you install them without them, what was the usage regime, how many km did you do

[MariuS6]

In what capacity are you giving this advice?

[K Simmonds]

As a mechanic who's had to pick out broken bits of plastic from way too many old Audi engines.

All that that shield does is prevent you from burning yourself with hot oil when opening the filler cap with the engine running, that is it's sole function.

Am vazut ca are roluri mai importante decat de a nu stropi cu ulei(mentinerea lubrifierii lantului si rol de ghidare)

[MariuS6]

I saw that it has more important roles than not splashing oil (maintaining chain lubrication and a guiding role)

[K Simmonds]

That can be the case with some newer Audi engines but not with old 20VT engines. If it really concerns you fit a new genuine Audi one and renew it every ten years.

When removed, they can cause a small amount of oil wetting around the cap but that's all.
