I've begun the "leak down test" on my IMS.
grant - Monday, 31 January, 2011, at 9:11:28 pm

I cleaned it off with a tissue, and now have it sitting on a 45 degree angle on a white buck slip, to see what leaks out. Fort the record, after 5 minutes a small drip is visible on the face of the seal - so something is.

Someone asked how much play was in it - if you rock the shaft as if one was stirring a mortar or using a joystick. Answer - there *is* play, but nearly none. Since Charles told me to go ahead, i will dis-assemble it and take pics someday soon.

Keep us posted ,It will be interesting to see how much comes out and how fast. Did you ask Charles if more northern cars have ims problems than southern cars?

nothing on clean white paper.

As to the N/S bit, no i didn't actually speak with Charles yet. And he didn't say in his note.

Shouldn't it be pointing down with the seal side as that is where oil would get in from and out from.

There is a rubber seal on both sides. Does it matter? Je ne sais pas. *NM*

Would crankcase pressure be a factor as to which side is pertinent? *NM*

Minus 40 degrees... Is that Fahrenheit or Celsius?

My point was if you are trying to establish if there was oil penetration through the inner seal then shouldn't you be letting gravity see if the oil leaks from the bearing through the inner seal. You can also rip the seal off and look and see if there is grease still in among the balls I guess.

I get the impression from reading posts from those who have done it themselves of watched that not all bearings show signs of penetration and those what do show it big time.

I turned it over. We shall see (literally, the pics will go up). Eventually i will cut it open.

Ao far no leak inner either. The problem is that its hard to keep it propped up on an angle.

There is an oil spot on the paper now. Unclear if this is from the inside, or just the lip where the seal meets the metal. The whole thing was (duh) covered in oil.

See for yourselves. 18-20 hours elapsed:

The oil spot on the left is from earlier. The one on the right formed over the past 36+ hours.

When I checked my bearing for oil penetration, I removed one seal - it easily flips out - and put the open side down on the paper.
No seepage was evident after leaving overnight and what appeared to be a little grease was causing the bearings still to drag when rotating it by hand.
The dual row bearing assembly had completed 47,000 mile with approx 9 oil changes over 9 years
