AFB cylinder head for VW 2.5 TDI engine, replacement part

Hello.

Does anyone know if the cylinder heads (or at least the camshafts, rocker arms, and hydraulic lifters) from a 1998 AFB 2.5 TDI V6 engine are compatible?
Are engines with the type designation 'BAU' manufactured in 2004 identical?

Regards,

Rafael.

No, the camshaft and rocker arms have been modified.

Are you sure that the masses are not equal? Perhaps only the part numbers were changed.

Could I not install the complete cylinder heads from the BAU engine?


Regards,
Rafael.

The 2004 V6 TDI engines have roller rocker arms and camshafts assembled from pipes and cams. For the 98 model, it features a sliding sleeve and a cast iron water jacket.
The probability that the parts will fit is not high, but I'm not entirely sure.

If you were to completely replace the head, it might fit. I just needed to make sure the distance between the open valve and the piston was the same, that the compression remained consistent, and hope that the camshaft settings were correct.
Maybe someone from a large VAG dealership can share their experience. The time has come when the older AFB and AKN engines are starting to fail, and they should have spare parts on hand, just like with the mass airflow sensors .

Do you have any white water or, even worse, bigger waves?

Although the thread is very old, it was just presented to me as a similar topic, so I'm taking the opportunity to use it.
Heads may be interchangeable, but not the inner workings.

Sure!

I'm wearing a combination like that. AKE engine with roller rocker arms.
It's quite a nice thing .

Hello everyone,

It's good to know as a new owner of an AKE model year 10/02... (feel free to criticize me, but this vehicle simply appealed to me because...) "Completely satisfied with the features/condition and the price."

Okay, here's the translation:

"Another question: When you shine a light into the oil filler cap, you can see two lobes. In three vehicles I looked at, I couldn't see or feel any signs of wear on those lobes, and the mileage was between 140,000 and 190,000 km. None of them had new camshafts installed yet. Does this wear only affect other lobes that are harder to see?" Or are not "all" vehicles affected?

1 year is a used car warranty.

Best regards,

Not everyone is affected, and it's possible that some valves are wearing down without you noticing. It's best to open the covers in 10 months and take a look.

No, better after 5 months. Then the warranty applies, and the dealer has to cover everything.

Yes, I guess I'll do it that way...

Best regards,

Okay! Usually, only the rear cams engage.
They really start to become problematic between 250,000 and 300,000 kilometers.
"That's when the control surfaces deploy."

How about you, Albrecht? What happens when you rev the engine? Is it vibrating?
This is usually the first sign of NW damage.

The engine runs smoothly and doesn't exhibit any other unusual behavior. Therefore, my question is whether ALL vehicles are affected.
I know what I was getting into with this engine. But that's why I have the warranty/guarantee.

Are there any measurement blocks where you can see something? For example, related to idle speed control?
Does long-life oil cause damage or is it beneficial? Or is a 15,000 km oil change interval better or worse? Are there any experiences with that?

You can be sure if you remove the valve covers, which, as I mentioned, I will be doing in 5 months.

Right now, I'm just using the new machine to get a little bit fitter, purely for fun.

Best regards,

According to Bj., yours still has the outdated NW components installed. The "good ones" arrived at the end of 2003.
Have you checked to see if they have already been exchanged? Speak, are they cast or machined?
How many kilometers are on the car?

He doesn't have any roller levers with IHU waves yet.

Mileage is 189,000 km. Nothing major has been replaced, and the repair history is completely clean.

I looked at 5 cars. However, the 2004 models were too expensive for me, and they didn't perform very well (although they had a 163 hp front-wheel drive).

The 180 horsepower quattro models (all still with the AKE engine) had between 141,000 and 188,000 kilometers (approximately 88,000 to 117,000 miles) on the odometer. According to the information available, none of them... "Repair history: what was replaced on the unit, and the front ones (visible through the oil cap) were all in good condition."

Honestly, I can't imagine that *every* 2.5 TDI vehicle on the road is affected, given the sheer number of them. I think someone from an Audi/VW workshop mentioned something about 80% once?

Best regards,

It would be interesting to see a photo of the oil filler hole, taken from the northwest.
Then I could tell you whether they are still the originals.
I would be really interested. Although almost everyone I know...
As mentioned, they were due for replacement after 250,000 to 300,000 kilometers.
There has also been a lot of discussion about whether the Longlife II oil was to blame or not.
But it's definitely a fault of the hardening process, not the oil itself.
