See the post above from Porsche 951.That is all you need to do.

 

I have made a mistake. I thought the OP was already in there, with the bearing in hand. Seems to be in error.

Given that, I agree that using a mag oil drain plug, and a full flow oil filter, change oil regularly and leave it as is until such time there is need to go in.

 

Not on the 99's

I'm not really sure what you are getting at? I have a lot going on with my car. I pulled my engine due to intermix. Had the head rebuilt and am doing all other preventative maintenance while its apart.

That other thread is unrelated. Geez.

 

I am already in there. My bearing is out...

 

OK, then install the LN Solution(journal type) and be done with it. You are investing in other parts of the engine, and consider leaving the stock IMS time bomb in there?

 

the stock IMS is out. All I really wanted is a stock replacement. It lasted 108k... If that isn't possible then I want a dual row for sure.

 

I understand the LN Double Row Solution is now available.
Now that would spell: Piece of mind!

 

To me, it's rather shocking that the problem got worse, not better, with each model year of the 996. I'm definitely getting my 04 into the LN solution ASAP.

 

No, the bearing width is properly adjusted for the retention circlip.

Just install it, all those physical differences are a non- issue, and have 20,000+ installs under their belts.

 

I hate to keep perpetuating this thread, as it seems it has been answered, but WHY would you want to put another stock, proven poor design, back into your engine when there are other proven improved designs available? Your engine is already apart, you need to purchase some part, why not purchase the improved design?

 

Also, there's no OE IMS Bearing... Not even a part number for one. Never has been.

The factory never intended for the bearing to be removed. That's what drove me to do it the first time.

Again, you have NO factory IMS Bearing option.

 

the reason for the desire is my bearing is in good shape after 108k. Never been swapped. I like that service interval better than 50-75k miles...

I am buying the LN it seems, thanks all.

 

The 75k service interval for the dual row bearing is just that. It doesn't mean the bearing will fail at 75k miles, but rather that it has reached the service life for the application based on operating hours.

The factor single row 6204 bearing with inverted race operation is only 1500 hours.

If you want to do this once, then install the IMS Solution and there are no more service intervals.
