Hello all,
I’m new to the forum but have been watching Eric The Car Guy for years now. My question is this: I replaced my clutch and rear main seal due to a very small leak, however, the leak was worse when everything was put back together. I replaced the oil pan, as well as the gasket 3 different times trying to eliminate that as the issue (as well as the PCV). So this time I pulled the whole motor because it was easier to get out then the manual transmission on a CRV. Below is a picture of the crankshaft where the rear main seal sits, there is a groove that you can certainly feel with your fingernail. Here are the options that I know of: go over it with an emery cloth and install the new seal not as far back so it doesn’t touch the groove, use one of the sleeve things that go over the crankshaft (I have heard negative things about these), take it to an engine building shop and see if they have any ideas, or purchase a used motor imported with approx 50,000 miles. Any help, suggestions, or ideas would be greatly appreciated! Thank you.

I would fill it with some jb weld. Use a small razor blade to apply it. Then
sand it to shape it.As good as JB Weld is ( and I use it quite often )…
Personally with out knowing exactly how it would fair, I would not be too keen to apply it to a wear surface.
The repair sleeve your concerned about is most likely the easiest and cost effective way to correct you issue IMHO.I’ve seen these sleeves fail due to installation error.
If you follow the procedure as outlined by the instructions, I do not believe you will have any issue.BTW, the only 100% sure way to repair a worn / notched / grooved shaft would be to have it metalized.
Which in this situation would be cost prohibitive.Properly installed, a seal sleeve will outlast the engine. Get a quality one that comes with the installer tool, and use 609 loctite on the ID of the sleeve to retain and seal it. Remove the lip on the sleeve by peeling it back so it doesn’t stretch the sleeve and cause a distortion.
I’ve installed many speedi-sleves over the years with no problems at all. Also get a viton (brown) rear main seal as they won’t harden with age like the Buna-N ones.
