Purchased the EPS cylindrical bearing w/ Oil Feed Modification. Just have it sitting in a box until the weather gets better. Not looking forward for the install but will have to get it done sooner than later. Currently rolling the dice with about 138K miles on odometer. Also have my replacement SACHS OEM Clutch kit sitting in the box too. Clutch still grips good. Took it to the casino yesterday on the backroads driving it hard. Still cannot get it pass 5,500RPM w/o turning into a chicken and letting off the gas. Looking for a 997 Shifter and my Function First Tranny Orange inserts are in transit to be delivered.

 

Absolutely! The grease was all washed out at 50K

 

LNE Dual-row hybrid bearing, 7 years/35k miles ago.

 

My 99 convertible (74000 miles) still has the factory dual row. I think that a less than 1% failure rate doesn't justify such expense. My Porsche specialist told me that he saw only a couple destroyed engines due to the IMS while his customers are crazy about it. I do an oil/filter change every 5000 miles and drive it like a stolen Porsche...

 

Eps roller bearing with oil feed

 

EPS IMS bearing upgrade with oil feed modification.
1999 C2 Cab.
Done at about 65,000 miles on a factory replacement engine (replaced 2004) that had 43,000 miles.
Installed at Vertex Auto in Miami which is EPS's headquarters. Met and shook hands with the inventor. Took me thru the install step by step as they did it.

 

 

Rolex, did you place your vote for EPS in the survey at the top of the thread?

 

Installed the IMS Solution myself, a couple thousand miles ago. I like the idea of a "once and done" installation that asks for no attention or service.

That it's trivially easy for a prospective buyer to verify that this bearing is in fact installed would be a plus if I had any plans to sell my 996. But I don't.

 

As my build date is 3/00 on my 2000 C2, I agree with DBJoe, although I only have 65k mi. on mine.

 

Installed the LN Single on my 2004 C2 when I bought it in June 2016 with 53,700 miles (did not know about the Solution at the time or maybe not out yet?) 27 months later and 18,000 miles all running strong. Original IMS was still in good shape.

 

I was fortunate enough to be allowed to see my bearing extracted. When they removed the original OEM Porsche bearing, the intermediate shaft began pouring out oil which was obvious sign the seal was compromised. Next, we closely examined the IMS bearing and noticed the center stud was showing slight play and the seal had pull from the edges. That was all the proof I needed that I had swapped it out in time.

 

Thank you for your insight. It wasn't intended to be unfair. The poll is directed at people that have swapped out their IMS bearing. The last two responses are meant to be rhetorical in nature, but it seems like a fair amount of people within this sample are sticking with the original OEM bearing.

 

I had my engine rebuilt by FSI in 2012. At that time, the Solution was not yet rolled out and their top level IMS replacement was a TRIPLE row ceramic bearing that was included as part of a modified IMS assembly. I believe it required engine disassembly to install so the most common application would have been as part of an engine rebuild and not as a relatively easy retrofit. Its gt about 25K miles on it now and everything works great!

 

Same here 1999 Convertible with 54,000 miles and original IMS. I have no plans on changing it. For the record my Porsche mechanic told me that every time he swapped out the the original IMS bearing for a new one, the original one looked perfect with no signs of wear.
