IMS again

This discussion however made me rethink 'hope it lasts' option to and oil fed solution.



Thanks for the input.



And now for those tires and oil, I will !!!!!!!!!!!!!!!!!!!!!!!! Ha Ha

Yeah, the oil-fed solutions are changing the bearing to an open bearing, which requires constant lubrication. (iiuc)

For me, I wish someone would develop a replacement bearing that's more like a traditional crank bearing, with a direct oil feed to it, and bearing "shells". This makes so much more sense to me, and would have the happy benefits of still staying largely "in-place" if the bearing failed, si timing remains close, meaning no other parts in the motor get damaged. It would also be easily replaceable if damaged.

But that would be FAR too easy for the Porsche community.... Haha. I mean, it'd be almost sacrilegious to put a simple and robust bearing in a motor with 5 chains, all those ramps and hydraulic tensioners, the craziest Air/Oil separator system I've ever seen.... etc etc.

It's already been done, sort of, but it still uses an external oil feed:

IMS Solution – The only permanent fix for M96/M97 engines intermediate shaft bearing problem

I love how they call it the "Permanent fix" but only guarantee it for 5 years!

You can always buy a 987.2. The IMS bearing in those are guaranteed for life. In addition, I will personally guaranty it.

haha! What I paid for my 986 plus the cost of another motor, if I should ever need one, is still less than half the cost of a used 987.2

So when you (Your significant other) puts a new roll of toilet paper on the holder, is it spin towards the wall or away from it????

I'll bet you can't search that here

There are several IMS kits which provide roller bearings which use pressurized oiling.

There is a kit using a plain bearing similar to the one on the other end of the camshaft and this kit adds pressurized oiling (The Solution).

I think the roller bearing is a disaster, regardless of pressurized oiling.

I'm talking about a plain bearing.

You just described the IMS Solution.

Cool.
I can't tell from their literature if it's replaceable bearing shells that can be replaced as maintenance items when doing a clutch, for instance?

And, I find this bold type.... interesting:

"DESIGNED FOR THE LIFE OF THE ENGINE. 5 YEARS / NO MILEAGE LIMIT WARRANTY"

The IMS Solution solid bearing is designed to go the life of the engine, we have never seen or heard of one failing, or wearing out. We are aware of a couple that have been pulled out of one engine (having suffered dropped valves or rod failure) and then reinstalled in another engine where they continue to serve without problem. No other IMS retrofit can be reused.

From conversations with those more in the know, they have no designed life expectancy.

Help me understand why no other IMS retrofit could be reused. Thanks.

As I wrote in post #8, it's already been done.

Plain bearing.

They call it a "permanent fix" but it's only guaranteed for 5 years! HA!

And exactly how long did Porsche warrantee the car originally?

To my best recollection, Porsche never made the claim that the car will last forever, or that it's "the last car you'll ever need."

My point is that if they make the claim of being the "permanent fix", they should put their money where their mouth is and guarantee it forever.

Let's see: Porsche sold you a $50K+ car (original price depending upon the year) and gave you a "limited" 4 year warrantee. LN sold you a $1K part, and warrantied it for 5 years, in a market where 1 year parts warranties are rare, and 30 days is more the norm. And you are complaining?

Porsche didn’t call it the “Permanent Vehicle” or “Transportation Solution”, suggesting that the car would never fail.
The “IMS Solution”, however, does suggest that (with a 5 year warranty).

Calling something “permanent” or the “solution” without the data to support it is deceptive, at best.

Away from the wall. I don't want the inaugural application to be with paint, wallpaper, tile, or cement.
