Front one piece seal 8ba
Do I need to put any silicone around the outside edge, or will the oil pan squeeze it to seal?

Re: Front one piece seal 8ba
The one piece seal is being set in a location that was never intended to be perfectly round the front cover is machined round however the stamping of the oil pan is not a perfectly round shape. When those two groves are placed on the block with the gasket for the oil pan included you now have a more oval shape than round shape. Since the two pieces of rope type seal material were able to conform to these outer surface variations it was not an issue. When you install a one piece front seal the outer surface situation will need some type of sealer. But if your putting this type of seal on the Ford reverse spiral grove I would think this grove will damage the seal. However the seal would work well if the seal surface on the crank shaft is smooth. From what I know when installed correctly the original design Ford type seals will work perfectly for many thousands of miles and at well over 200 MPH

Re: Front one piece seal 8ba
Thanks for the info, I bought the kit with smooth spacer and one piece rubber seal. Thought I would give it a try.

Re: Front one piece seal 8ba
Not a lot of miles on either of mine, but no leaks and I like em. My reading here has indicated the seal should work okay with the spiral groove as well.

I would recommend measuring the O.D. on the crank (OEM=1.311"/aftermarket=1.307" nominal) and the I.D. on that sleeve! Sleeve should be 1.3115"? You don't want it too loose? it should slide on the OEM shaft "snugly", slightly lesser on the aftermarkets. Important: No matter what shaft you're using it's good practice to put some sealer between those sleeves and the crank snouts, it stops any oil from "seeping" between both pieces and getting to the damper/bolt. We use "The Right Stuff" there also! Thanks, Gary in N.Y. P.S. When we assemble our units here we do use a "thin" coating of "The Right Stuff" on the entire circumference of the seal, so far we haven't a single leak ever!

Re: Front one piece seal 8ba
there is a video on Youtube on how to do this , it shouldn't be hard to find.
I was meticulous on installing mine [21 stud].. Damn it leaked bad , popped the old rope in there and its pretty damn good now.

Re: Front one piece seal 8ba
3twinbridges,
I watched the video on YouTube and took mine back off and separated and added silicone and put back together. I would rather have piece of mind than leaking seal. Wasn't any trouble at all the bolts automatically start backing themselves out when I walked up to block. |

Re: Front one piece seal 8ba
Glad you brought this back, I was going to also to cover a few more items!
When you install the sleeve on the crank (up against the oil slinger) make certain the key for the timing gear doesn't contact the sleeve and keep it from bottoming out like it should. The slinger is also "keyed" but the key itself may be a bit too long (photo below), this area needs close scrutiny! Quote:
Thanks, Gary in N.Y. P.S. Here's a close-up of the area I'm speaking of, it shows just how close the key, the slinger and the sleeve really are, we "trimmed" that key to clear it all.
