THE IMS BEARING FAILED IN MY 997! My 997 has been at Flat 6 Innovations since July. Jake said he had never seen an IMS Bearing go out on a 997 street car. As you all know the repair/rebuild is not cheap. So let me tell you again who is sick of IMS Bearing. I AM SICK OF IMS BEARING!!

Sorry for your loss. Would you share how many miles you had in the 997 engine when it went south? Was it the original grease-filled version or the seal had been removed? Cheers

There are two problems with these experiments:

1) The bearing is more submerged in oil unless you keep your oil level below the minimum.

2) He spins a whole bearing in oil demonstrating that oil gets thrown out completely due to centrifugal force. In fact, the center stud and the inner race of the bearing is immobile and constantly supplied by oil leaking into the gap between the bearing and the flange inside the bore in the crankcase, as shown on the picture. It`s hard to imagine such circumstances when oil can`t get there when the oil level is at least half way up to the top of the shaft.

Pedro has been working on Boxsters for a long time and where he says the oil is sitting at is probably correct.

Pedro started the injecting oil into the bearing deal with his "DOF" kit and Flat 6 Innovations changed over to injecting oil into the bearing with their "Solution" kit.

So with Flat 6 Innovation changing over to injecting oil into the bearing, I believe Pedro has merit to his claim.

Sorry, but it was the other way around; Jake Raby got the patent both for the solid bearing and the oil feed, which is why Pedro could never lay claim to it or patent it (which the original developer - Tuner Motorsports - tried, but was denied. Pedro is only licensee of this product, not the developer).

BS, Pedro came out with the "DOF" long before Flat 6 Innovations came out with the "Solution" and the "DOF" is patented.

i don't even think it was TuneRS that developed it, was it? I recall reading the big long thread on ... pelican? ... where it was just some guy working on it, developing testing jigs, etc. i'd thought that TuneRS might have bought the idea from him?

Regardless of how long he`s been working on Porsches the oil level sits at a much higher level even if the the oil level is at the minimum sign of the dipstick. You can find info about it on my show&tell thread if interested. Everyone who makes a bunch of money on these kits has an interest in telling you DOF is critical and your engine will fall apart if you don`t have it installed.

Actually, apparently now if you have an IMS kit to sell you have to add DOF to it, otherwise it won`t sell, regardless of being necessary or not. I just looked at the EPS website about the roller bearing and it`s kind of funny that they also add DOF in their kit even though they think it`s unnecessary

Just watched the PCA Spotlight: Types of IMS bearing retrofit kits youtube video that has Jake Raby in it and they put up a notice that you can remove the seal and there is no need for direct oil feeding.



So what's all the hype over the direct oil feeding solutions?

[mikefocke]

There are three types of bearings being used in IMS replacement kits. Ball, Roller and Flat. What may be appropriate for one type may not be for another and yet may be required for a third. The larger the bearing surface the more heat must be dissipated and thus roller thrust and flat bearings require different oil amounts than ball bearings.

that sucks. best wishes

I'm trying to get to the bottom of this. I just left a comment on Pedro's video about the patent and he replied back saying that the "DOF" is patented. I asked him for the patent number, lets see what he comes back with.

I know they tried to patent it, but my understanding is the application was denied.

I have seen "patent pending" in their early literature, but now there is no mention of patents, nor will a search turn up one.

.....as many folks have posted, you can choose to just drive the car and not worry about this and take your chances.

The odds are it will not blow.

But if it does.....

I shipped my car to Jake Raby and he installed the “IMS Solution” in my car and I have put 30,000 miles on it.

If you want to replace your IMS, I highly recommend the “Solution”.

I am not saying you must change it.

I’m just saying if you ARE going to change it, get the “Solution” and be done with it.

I drive all over with no worry.

Priceless.

TuneRS web site still lists the DOF as patent pending.

As one who shepherded a patent claim through the process it can take years before it is finally granted. You have to educate the patent examiner in the technology and how your design differs from anything else (s)he comes up with to initially deny your claim on the basis that it is too similar to someone else's. Which means a combination of patent lawyers and technical experts. And each time into the Patent Office the "paperwork" waits till an examiner with the right background can get to it which can be years. An offshoot of an understaffed government agency.
