http://www.correctcraftfan.com/forum/forum_posts.asp?TID=38579" rel="nofollow - '82 351W Rebuild Full thread I received my Bottom end marine gasket set from Summit http://www.summitracing.com/parts/FEL-17166" rel="nofollow - (Fel Pro Set) , and I knew I would have to buy a separate rear seal to get the correct two piece design, (kit came with 1 piece), but I thought the front seal would be the same. The oil flow wick lines rotate in the same direction, but the new one has an outer lip and looks different.  Do I need to order this http://www.summitracing.com/parts/fel-17795" rel="nofollow - Fel-Pro 17795 seal? Or will my new one with the larger lip work? **EDIT** Also, I'm looking at this and these wick lines and my RH rotation seem like they would pull oil out?? Or am I not picturing it correctly? |

rear seal is one piece not two. Hard to find the one piece reverse rotation seal. I found one through a web site called alexsparts.com Think this is it anyhow. |

My rear seal is a two piece 100%. It was made before they switched to the one piece. Wick lines are in the crank so an automotive 2 piece will work. See http://www.correctcraftfan.com/forum/forum_posts.asp?TID=38164&title=351w-rr-seals" rel="nofollow - this thread |

| My felpro kit came with multi piece pan gasket, I ordered the one piece marine pan gasket separately |

| Reverse rotation one piece seals have always been available from PCM. The new deal should be fine as long as it doesn't wildly change the installed depth of the seal surface on the crank nose. |

I thought that too but http://www.skidim.com/SEAL-FRONT-COVER-RH-302_351/productinfo/R047044/" rel="nofollow - Skidim only lists a "smooth seal, with no lip" "Older ones have ribs with lip". What makes it reverse rotation if there are no oil wick/helix lines? I'm still confused why the wick lines on both the new one and old one look like they would pull the oil out? |

Well I called Fel-Pro technical hotline and they said the kit I bought http://www.summitracing.com/parts/fel-17166" rel="nofollow - Fel-17166 is for standard rotation only  If that's true, was my old seal the wrong one maybe from the previous owner? I guess 17795 is the correct front seal then? no wick lines? http://www.summitracing.com/parts/fel-17166" rel="nofollow - Fel-17166 |

Just wanted to post a picture of Fel-17795 for anyone looking at this in the future. My "Marine" kit came with a standard rotation seal, which was confusing because it had the same directional oil lines as the one in my engine, maybe by the PO? Mystery unsolved for now. The correct RR seal is below, and it is SMOOTH with no wick lines.
