Crankcase Breather 54 130tdi

[martuk]

Hello All

I have had a Est Highline now for about a month.

The car has some back pressure when taking filler cap off when running
and also smokes when the accelerator is blipped

The vehicle has a full documented VAG history and has done 87k.

My thoughts are its not wear on the bore or slipped rings as performance is good as is mpg and the low miles on the vehicle. After trawling through sites like this there seems to be a common link with the crankcase breather filter

I have a couple of questions for those in the "know"

1 ) Does the 130tdi have a CCB and is it easy to get at. is it a case of taking the
engine protector off and just stripping the hoses out?

2 ) If so does it form part of the manufacturers service and has to be changed
at intervals recommended by the Manufacturer, or is it as and when required.

Many Thanks in advance

Hi there. I had the same problem with my v6 tdi. It turned out to be the PCV valve, which is the breather for the rocker covers. It was buried in the middle of the engine but a new one did the trick.

Can I just bump this up for more opinions

Thanks

It is a bit young for any vent pipe problems but it is a very simple system. Follow the breather pipe along and check for problems. Has it had a cam belt recently?

Thanks I will strip off the canopy and track it. Is there a filter within the breather system

It had a belt the day before I picked it up. I had thought the timing could be out a little
as a result of the beltchange, but wouldnt it be coughing and spluttering if it was missing?

It may be worth having the timing checked if it wasn't done at a VW garage/specialist. Take the top belt cover off and look for paint marks used for alignment, if there are any it wasn't done correctly. The breather filter is in the cam cover, I can't imagine it having a problem there though or with rings. They do have quite a bit of back pressure if you remove the oil filer cap with the engine running.

Hi Crasher

Stripped the canopy off and located the breather coming out of the top of the cam cover.
I disconnected the hose with the engine running and very little blowback came out
of it, the majority was still coming out the filler cap.
Could it be the filter itself in the cam cover is blocked and this is restricting the flow out
so its got to find another way out?

If so is it a case of just stripping the cam cover off and replacing the filter, are these
items you can buy over the counter at a VW

[Crasher]

It means a new cam cover 038 103 469 AE (for a 2004 AVB, AVF or AWX engine) at £98.24 inc. VAT but I still can’t see it being blocked.

I have an audi AWX 1.9 tdi. And I have the same problem.So then can anyone tell more precise about the location of a crankcase breather and the process of changing it?As I understand ,that it built in cam case,so it means that i have to take it of first to change the filter?

[Crasher]

The crankcase breather is THE cam cover, you cannot dismantle it and I have never seen one beconme blocked.
