Has anyone tried this, looks like a very robust solution:

The topic has been beat to death. Try a search.

Jrebot2,

Oh, how the love abounds)

There are several different products from a handful of companies and variation’s on how they approach the IMS problems. I would think each chooses what they feel would work best for them to get the desired outcome. The is a lot of info to be found and I have spoken with most of folks hwo design the IMS options and they were very helpful. Each feels they have the best product as they should. We get to figure out which would work best for us.

Enjoy the journey.

Look up how many times the OP has already asked about this same subject, one that has already been covered to death.

As someone once said, search is your friend.

Wow dude, im new here and trying to learn. Looks like you don't have much to do. I appreciate the search I am using it.

New to the forum or new to Internet?
Nobody is trying to give you a hard time, but when you bring up a topic that's been covered to the point of exhaustion, no one will want to participate in a meaningful way.

If I were to state my opinion on the bearing, the same guys I've debated with in the past would jump in with their counterpoints and we'd be having the same debate again. I think we are all tired of that.
There are certain topics we just try not to discuss, like the IMSB choices, oil, tires, cats and guns, etc.

Best of luck!

I'm running one. No regrets.

Flaps10,

Lived in Steilacom for 6 yrs I really wished I still did. Did you spend the extra $99 for the oil feed?

It's a cool town. Super quiet. I've since moved to north Tacoma.

Did not spend the extra $99 but the kit included the punch they suggest you use to pierce the passage anyway. I didn't love that method because you didn't really have control over the size of the hole you make, and the web you are piercing is a very thin cup pressed into the shaft. Whacking it with a hammer and punch didn't seem too smart.

In my case I had the shaft on my bench so I drilled a hole that was in the middle of the range they suggested and blew the chips out. I also pinned my sprocket onto the shaft with set screws, blah, blah.

[Pdwight]

So how about Oil ??????

Why would you get an 05 and change the IMS? Cost of doing all that, you could pretty much be in an 06 with virtually no IMS worries?

Having followed these IMS threads for years, I've come to the view is that there is no unambiguous answer as to which IMSB is the best replacement option.

Given the consequences of an IMSB failure, my criteria is what impacts do the IMSB replacement candidates have on minimizing potential engine damage either during the stages of failure or everyday operations.

If one's goal is to preserve the engine for a long as possible, then price SHOULD NOT be a major factor when deciding. If on the other hand, one wants to keep the engine running for 5 years or less, then any of the options will probably do and price should play a strong role.

And if you're torn between options, then pick the IMSB option that damages the engine the least when it fails regardless of price. Otherwise, you'll still wonder if you made the right decision

As a shop owner, I can only reiterate you point, but the reality is that as these cars age, they become cheaper, which seems to lead to second or third owners that care more about cost than perhaps they should, which quite often leads to problems. As the result, we long ago adopted a simple position on repairs: If you want us to fix something, we are only going to do procedure's and use components that we have confidence in; if cost is your only decision factor, take the car somewhere else. We simply do not need your business badly enough to cut corners or sacrifice quality. Come back's and problems resulting from cutting corners are a shop's worst nightmare, and the least economic outcome for owners.

Generally, I would agree with you. However, roller bearings are NOT expensive generally. So really, when looking at the options, some are ridiculously over priced IMO. There are some specialized bearings, but it would seem that for the most part, the bearing supplied in a good portion of the kits are not particularly special. So, the cost then must be justified in the other components and "R&D". Like some life saving medications, there seems to be a bit of a soaking going on with some of these components. In the EPS case, given the part warranty (one of the best ones) and ZERO failure rate, plus the cost, it seems to make pretty good sense. It would be interesting, after all of this IMS discussion, to see who used what, when etc. and then cross referenced the secondary failures, if any, in the given replacement systems. Probably never happen.

Was the question asked in relation to the 2002 S the OP has now sold pending funds or the OP's incoming 987?

[jrebot2]

Hi, for the 987s 2005

[mikefocke]

Ah, the 2005 where you have no idea which bearing the engine has until you remove the transmission....

[thom4782]

Think 'confirmation bias' when reading IMSB, oil or tire comments.

As others have said, the IMSB question has been beaten to death. Along the way, many have decided which option they prefer. Their comments and recommendations tend to reflect / justify those decisions.

Unfortunately, there aren't enough 'verifiable' facts available to tell the community whether one option is the clear winner. And even if such information were available, some would reject and argue against those findings because they run counter to already held beliefs.

Just so you know my confirmation bias...my 01S has the IMS Solution installed. It's been there for about 21 months. Why? I'd rather have a plain bearing than a roller or ball bearing ISMB. I could have opted for a lower cost option, but I don't worry about it anymore and that alone was worth the extra money.

I put one in mine 13K ago. Kit came with slotted oil pump drive shaft. I did use that and punched a small hole through end of the shaft. So far, so good.

Someday when the engine dies, I am going to a postmortem inspection and see how this bearing fared.

[ksjohn]

One other thought:

One thing that attracted me to the EPS bearing system was ability to modify the oil pump drive shaft and the IMS so that oil would be continuously pumped to the bearing. I know this oil source is not cooled or filtered which is ideal, but still it is a continuous oil supply.

Why could you not combine this feature with a simple, non-sealed single row ball bearing? A ball bearing may be a better solution than a roller bearing and the cost could be minimal depending on the source of the bearing.

I have never seen this option discussed anywhere.
