How much rope seal do you leave proud?
I see a lot of different measurements. The little gasket that came with this as a guide is really thin, .015. I don’t trust it, how much should I leave above the pan and timing cover?
I think I should least be an eighth of an inch.The cork gasket measures about .080”. I know the rope will smash down pretty good. |

Re: How much rope seal do you leave proud?
Best gasket kit Supplys a razor knife and a thin wood shim as a trim guide , seems to work good .

Re: How much rope seal do you leave proud?
How thick is a thin wood shim guide (1/16, 3/32, 1/8, 1/4)?
Ralph: Read everything related to oil pan/crank rope seals you see here. There are lots of thoughts. Some kits give you instructions, some do not. https://www.google.com/search?q=how+...hrome&ie=UTF-8 Last edited by 19Fordy; 05-16-2022 at 01:20 PM. |

Re: How much rope seal do you leave proud?
I did push it down/ rolled it with a socket. It doesn’t seem like I’ll be able to get a whole lot more of that excess to go down in there.
So how much will it crush down? I like the push pins idea, I Will definitely order some of those. So I read that article, but I did not see the answer to whether the pan gasket goes under the rear cork gasket or just butts up to it. I plan on putting the cork seal in place first, which I think you have to. So it would almost be impossible to put the pan gasket underneath it. So I’m guessing just butt it up and put some RTV on it? Last edited by RalphM; 05-16-2022 at 03:16 PM. |

The last Fel-Pro gasket set I used also had a trim guide, razor knife, and instructions.

Re: How much rope seal do you leave proud?
I jam crammed mine in as best I could, which left big mushrooms at the two ends. I just trimmed the excess mushroom and left the rest, ...Been a while, but I think it was about 3/16" proud at that point. I expected trouble mating pan and timing gear cover, but no problem, and no leaks.

Trim the pan gasket around the outer edges of the rope seals. Then use a small amount RTV only around the outer area of the rope seal this will seal everything perfectly.

Re: How much rope seal do you leave proud?
Ooops! I used it for both ends on the last engine I built and no leaks!
However, when I dropped the pan to replace the flakey Speedway oil pump with a genuine Ford unit, it developed a slight leak in the rear seal. I don't think these were designed for more than one time use. |

Re: How much rope seal do you leave proud?
I think the gasket set quality has slipped because I always just used the rope seals as supplied and they weren't meant to be modified. I even remember note inserts saying not to trim them.

Re: How much rope seal do you leave proud?
Well I went back at it and was able to push it in a bit more. About 1/8” to 3/16” above the pan flange. I think it should push together without any trimming, like Ronnie said, when tightening. These pans are not flimsy like some cars nowadays!
Thanks! |

Am I the only one who was taught to soak those in oil before installing them?

Re: How much rope seal do you leave proud?
As for the rear main cork seal, I believe the cork pan seal is laid down, then the rear cork seal goes over that. Am I correct with that?
