Is this the correct orientation for the assembly of this oil slinger shield and seal? It's hard to see but the o-ring is already installed on the nose of the crankshaft. TIA. (IMG:style_emoticons/default/beer.gif)

I remember pulling it off during the tear-down, which was documented with many photos but can't find a pic of this coming off the crank. Anyone?

You sure about that? (IMG:style_emoticons/default/biggrin.gif)
Haven't ever seen an oilslinger on the front of a type iv crankshaft. But, it needs the right o-ring and seal to keep it from leaking. BTW your quick progress with multiple parts of your project motivates me. Starting at 7:00+: https://pmbperformance.com/pages/ian-karrs-...ne-build-videos. |

I've taken several 1.7 and 1.8 engines apart but this was my first 2.0L so I thought it was something particular to that. |

Ok. The front crank seal (FMS?) just arrived today. I’m not going to be putting these weird parts back in unless I hear something from someone. Just going with the o-ring and the seal.

Fred, I don't remember those on my 2 liter. But make sure there are know scratches on the fan hub where the seal edge rides.
