Yet another potential reengineer of the OEM part, http://europeanpartssolution.com/instructions/ has a roller bearing retrofit kit. I hate to do this...thoughts?

Cool! How much$$$?

$599, looks interesting.

I posted that before asking if anyone had info or could even get to the installation video. has anyone seen the vid? If so how did you get to it?

5 years warranty is nice!

No oil feed, just a different bearing. With all the dead pages and spelling errors on the web site, I wonder if they wanted to say external rather then eternal.

It says $599 on the ad. Looks interesting.

Well add one more option to the mix which is good for us consumers. I'd be interested to hear comments from one of the members here that actually installs one of these.

Vertex is in Miami, they sell various aftermarket parts but they also rebuild engines and transmissions. Among other things, they sell cars on the bay. Recently they had a couple 996s that said "0 Miles on new engine" and that the IMS had been upgraded. I called on one of them and spoke with the proprietor who told me about the roller bearing they had developed. He said their bearing even in single-row configuration is several times the load capacity of the ceramic LN bearing. And he said the problem with "The Solution" is that if the external oil feed malfunctions, the crankshaft-style bearing will heat up and seize quickly. He said there would be an article on their bearing in an upcoming Excellence. He said they've had quite a few people have LN bearings removed in favor of their roller bearing. He said they've been testing it for "a while now" with no failures, although he declined to say how many bearings were tested and for how many miles. All hearsay of course.

And theirs is still a steel bearing and still fitted where it wasn't designed to get a lot of lubrication. Which is where the ceramic bearing excels: superior longevity in cases of heat and inferior lubrication. I'm still not convinced that if the LN single-row bearing is properly installed, and the engine has not had a failing or failed stock bearing and therefore a crankcase full of debris, that the bearing can't last far longer than the conservative 50,000 miles LN says. The vast majority of stock bearings last longer than that.

I interpret this rating as more of a liability and CYA to maintain the product's squeaky clean reputation.

I mean look at some of those wheel bearings that see more load and shock(albeit with grease intact) go to 150k+.

What about this oil feed flange that lubes your bearing?

There's been heavy discussion and documentation over at Pelican during when the guy designed it before selling the patent awhile ago.

The product at Turner seems to be more refined since the original though.

I think a sealed ceramic hybrid bearing is the ticket. When oil enter the bearing, the seals will act as a barrier and keep the oil inside. Without the seals, any oil that accumulates inside the bearing when the engine is shut off will be displaced through centrifugal force as soon as the engine is running. I do not think splash lubrication is adequate.

That's what I'm running. With almost 10K km, so far it's holding up. I've also put about a third of a litre of synthetic engine oil in the IMS, behind the bearing. Figured that when the bearing seal start to leak, this extra oil will keep it lubricated for a while.
