Speed sleeve for Cam seal /470 required items

[Benny67]

Hello there,
Just did an oil change and believe my Cam seal on my 470 might be leaking (kinds milky oil) Does anyone have the part numbers of the speedi sleeve and seals needed to do the job?
I did the job once before so I know what needs to be done but lost the information for the sleeve and seals.
Thanks

Here's an older thread with some info:

3.7 mercruiser speedi-sleeve for cam shaft

I have read several posts for the camshaft issues being scored from the seals and causing leaks. I replaced the seals in my 488 mercruiser last year and it held for about 5 days or 20 hours of use and I did notice a bit of a grove in the camshaft but it didnt seem horrible so I just used emery...

Did you try to poke a hole in the weep hole to see if it was blocked. That hole should leak out coolant before it makes it past the 2nd seal and into the engine oil if that 1st seal is shot.

Yes. I got nothing out.
Chances are the antifreeze is from the leaky riser gasket I just fixed. I'm thinking it may have weeper through the #4 cylinder over the winter. I did find some antifreeze in it when I was preparing to initially start up this year.

I'm just looking for the part numbers of the seals and sleeve to order them so if it turns out to be the issue I'll already have the parts to do the job.

I'll pressure test tonight, if it's leaking I'm going to just go ahead and change. them anyway. If it's holding pressure, I'll clean the oil and run it for the season.
Before saying it, yes I did a compression test. All the cylinders are within 5% and in the 130 range. Motor runs fine other than that.

The job I did before was on my starboard engine. This is the port engine. I'm unsure if it had the speed sleeve mod done to it yet.

Take your time installing and verify a million times it's going on straight after each hit. I recently did the job and ruined 1. I ended up shaving/tapering the very front of the cam shaft ever so slightly to allow it to start on easier.

Also used this although the outer most triangle shapped gasket didn't fit for me, I just used great stuff instead

use a can of freeze it on the cam snout and heat the sleaves up with a 900 degree heat gun. no pounding at all, just grab with welding gloves and slip on.

im to old to pound anything. I have a freezer, torch and oven for most bearing installs.
