which ims bearing upgrade

[Smallblock454]

@boxster:

I think that's a lot of bla bla from Pedro.

There are a lot of different kinds of bearings made for special applications. Also there are different quality grades available. He also didn't name manufacturer or type, nor the specs. So you can't say that ceramic is bad and metal is good. That's complete bulls…t.

The bearing has to the right one for the application. I did some research on that a while ago. And i'm pretty convinced that there are ceramic roller bearings that won't fail within the given specs. But these are not the china cheap ones.

A sealed bearing is always the better solution. Problem is the under- / overpressure in the tube. Oil feed has in my opinion some disadvantages. Oil has to be clean and you can't prevent to swap uncleaned oil from the oil pan to the bearing. An oil line can break. Also there will be oil in the tube.

So in my opinion the best is to solve the under- / overpressure problem first.

That's not against Jake's or Pedros or any other solutions. They work, but you'll have to do a lot of oil changes and the solution won't work for a life time. So you'll have a lot of follow up costs that i don't like.

So, given that I am not planning on removing the engine from the car, LN's bearings without additional oil feeds is the best solution for my 99 spec car?
Also, as i stated before,I dont use the car much, and since statistically those are the type of cars that suffer the most,will LN's bearings have the same problems with cars that dont get used much? They say they life their bearings at 75000 miles or 6 years, since I don't use the car much, if after 6 years the bearings will have 20000 miles on them, will they still have to be changed?

Hi,

first of all you'll need to make shure that the installation is 100% correct. If you don't have the tools, knowledge or know how i would say change your motor oil yearly with a high qualitiy oil, change and examine the filter and leave the bearing alone.

Additionally - if you have a double row bearing engine. The bearings of these engines don't fail that much as single row bearings. And there are a lot of others causes why theses engines can fail. So don't go crazy on thinking abount the bearing - that's my personal opinion.

Well, 6 years or 75k miles means 6 years or 75k miles. Perhaps Jake can answer this question. Also Jake should give you a recommendation which of his systems match best for your car.

The only one thats Patented. The only one that removes at least 11 wear parts from the system. The IMS Solution.

Its funny how people seem to have forgotten the days of being told the IMS Bearing was impossible to replace. Its funny how those that have come along later have ridden our coat tails, and used the tools that I invented, and the procedure that I developed to install their copy cat systems.

I remember making the first post about removing an IMS Bearing, and at that time I was told that I was lying, that the bearing was impossible to extract, or replace. Today, the tide has turned, and what was once black art has become a market that want to get their part of. Too bad they'll always be one step, and several years behind.

Yes but the ims solution is going to take a while to be available for the dualrow from what I understand,right?
Can you tell me what the ceramic bearings act like on "garage queens", are they as sensitive as the conventional type when the car isn't used much, or are they more resistant? And how about the question I asked about the life of the bearings,if after 6 years they have 20000 miles, will they still have to be changed?

Maybe it's time to think about something that was discussed in the What type oil filter do you use thread. Oil filter filtration is not 100% they have a allowable particulate size that passes through them. Some of these particles are ferrous, this is why the Filtermag was developed. No ROLLER type bearing likes to have debris contamination. So continuous oil spray or splash lubrication has it's downside. I am not affiliated with or in any way compensated by LN or Jake, but the only bearing that has the clearance to allow this debris is the plain type bearing in the LN Solution system. Choose your own medicine.

Do you mean deep-groove-ball bearing or roller. There is a huuuuge difference in IMSB terms. Don't get us started on that again!
Filtration - suggest you research the difference between the OEM filter and the LN full flow+Napa Gold spin-on filter. By-pass is a more significant risk than filter pore size according to the experts.

I am referring to both roller and ball. By filtration I am referring to the the filter efficiency, not bypass, ( I have LN, NAPA Gold and Filtermag to eliminate bypass) this is not the same thing. The Filtration efficiency of most filters is only to ~10 micron first pass. This means there is always some particles that simply pass through the filter.These are continuously circulating to some degree. These particles are fine in a plain bearing where there is no contact and the bearing rides on a film of oil that is greater than this particle size. That is not true with a roller or ball bearing where the balls have contact with the races, and therefore do not like debris.

And that's Patented, too.

Filtered oil, and "just filtered oil" are two dramatically different things.

Oh, and to the camp that says the IMS Solution can't live without it's oil feed line? I have some medicine for you, too.

I just bought a '99 in August and immediately took it to a certified Porsche mechanic in Toronto and had the IMS done. He also said that it's now good for 6 years. He also put a stamp under the drivers door stating the date the IMS was done (apparently this is something that S/B done whenever any IMS is done). I asked him if the IMS replacement was related to time or km driven and he said time, regardless of how many km were driven.

Yep, thats what I'm thinking as well, that no matter the miles,since its now considered to be a service part, you have to change it every six years (for dual row)
