Polo 1.2 6R CGP Engine rebuild

Post by UKWaffles »

Hi,
Hoping someone can save me a little here, doing a polo 1.2 09 model CGP engine rebuild.

Have most of the bits back on. But I didn't / forgot to take note of the camshaft carrier order.

Took it off and bar the front cap / carrier the 3 similar ones I can't remember their order. There any information on this? Can't seem to find solid information on their order I assume it matters so.
Thanks

What are those small notches in them? Did you put them there?
One has 2 notches, the other has 3. Might be indicating the order.

Well s**t, I didn't even see those.

Quite Possible! as in that position the cams do feel the best overall when attempting to spin them all over. I didn't add those so they must be from when they were machined / installed from factory.

Just for general information, those camshaft bearing caps are line-bored together with the cylinder head at the factory, so they cannot be replaced individually (no part numbers in ETKA).

I guess those notches/lines are your lifesaver, the generic VAG order from Timing Chain to Gearbox is:
1 Notch = Cap 1 (Timing)
2 Notches = Cap 2 (Middle)
3 Notches = Cap 3 (Gearbox)

You must NOT flip them 180° or the camshafts will seize.
It is possible they have small casted arrows... look closely for any small arrows or letters (like 'E' or 'I') on the aluminum body.
If you find them and want, please, post here the images so we can help you double-check the exact orientation before you torque them down.

Yea I know they are line bored which is why I have been pulling my hair out!.

Totally forgot to take note of where they where before. Going off the notches I have them in the correct chain to gearbox order now, just need to make sure they are on the correct way around. I based it off the document you attached as it appeared the rear part of the caps with the nib was on the rear of the fitting position.

So seems I have been saved but this, I will add some pictures once I clean it all up and before they are torqued down

Thanks
