22350 Posted July 17, 2023 Report Share Posted July 17, 2023 Hey guys. I was having an issue with the rear seal on my new engine. I would have bet the house that the rope seal we put in was correct I looked through the threads and it is repeated over and over that the seal they are using is 3/8". I have attached a picture of the Best Gasket 3/8" rope seal and the groove it is going in, which is .234". That's not going in, but the groove is 3/8" deep. Also, the previous seal appeared to have too much clearance. Was able to get a feeler gauge in there Does anyone have a part number or description to get for this seal? Quote Link to comment
Stoffregen Motorsports Posted July 20, 2023 Report Share Posted July 20, 2023 Yeah, good luck with that. Have you tried a local machine shop? This came up on Summit's site - https://www.summitracing.com/search/part-type/rear-main-seals?SortBy=BestKeywordMatch&SortOrder=Ascending&keyword=rope+seal There are lip seal conversions for various cars that originally came with rope seals or no rear seals. MGTD, Austin Healey Sprite, etc. What is the size of your crank journal? And the size of the groove in the block? Quote Link to comment

Crashtd420 Posted July 20, 2023 Report Share Posted July 20, 2023 (edited) And actually available.... https://www.nissanpartsdeal.com/parts/nissan-seal-oil-cra~12279-00h10.html Might be able to get from the dealer too.... I see a local dealer has 1 on ebay... Also see a listing with an extra oring or something Edited July 21, 2023 by Crashtd420 Quote Link to comment
difrangia Posted July 20, 2023 Report Share Posted July 20, 2023 I know nothing bout the Britt stuff, but the E1 & J-Series Datsun engines have a flanged crankshaft. Any change to a lip seal would have to be a split-seal. 1 Quote Link to comment

Keith I agree, I'd go with the one from the dealer .... I put that up because it showed an extra o ring or something. I didn't know if that's something that comes with the one from the dealer or if it's important... I killed the link but left the picture.... Quote Link to comment
datzenmike Posted July 21, 2023 Report Share Posted July 21, 2023 China has a 5 thousand year history of graft and corruption and today they are the biggest counterfeiters in the world. 'Genuine' Nissan packaging and labels shouldn't be a problem. Ebay and Amazon do nothing to stop counterfeit products. Quote Link to comment

I remember doing it, but don't remember which motor we did it on... Quote Link to comment
