Conversion of 8V 2H engine to 16V KR, and white smoke

Dear friends hello,

I hope everybody is fine and staying healthy. I have been doing that for the past month (in Greece) and it seems things have been getting better. I also had time to do a conversion on my car VW Golf Cabriolet 1.8 2h Engine (98PS).



I swapped the head with a KR 16V. The block remained the same. So it is a 16V 1.8 with Digifant on top. It runs very well. The problem is that every morning I get thick white smoke. This is a hot climate, it is not condensation. The car is burning oil for the first couple of minutes.

The 2H engine block did not have the output in order to install breather assembly (part number 027103772A), so I instead installed this output, and then I installed the Crankcase ventilation pressure regulating valve from the 8V. As shown in the pictures below.




I also added the Crankcase Ventilation Vent Valve (part number 06A103465), as shown in the following picture. I did not connect it to the intake yet.



The thing is that the car sends quite a lot of oil in the intake, even after I installed the Crankcase ventilation pressure regulating valve from the 8V. Not just fumes.

So the question is, how do I minimise the amount of oil to the intake? What do you think I should do?

Cheers,
George

I'd be interested to see a guide on this build. Can you use any of the heads (9A, ABF)?

What ECU are you using?

when it was an 8v, i had the vw_pilot chip. I am still using the digifant parts, so ECU remains the same with the vw_pilot chip. You can use all existing parts from the 8V. The difficult part is where to connect the blue temp sender, which helps with idling. I got a part from an Audi a3 for that. I will send the pictures on it, directly connected to the radiator. you can see it in the first picture.

the other difficult part was injectors. 8V ones could not fit, so I used injectors from a Fiat Uno Turbo, part number 0280150708. Same ohm range, same fuel spitting capabilities.

As far as the heads are concerned, I am not aware of the other ones. I had an old KR engine sitting, so this is what I used.
