Oil fed intermediate shaft bearing upgrade?

Recommended Posts

While researching another problem with my Boxster, I noticed a company is advertising an oil fed intermediate shaft bearing kit, which seems to use a modified cover and a hose to feed oil to the intermediate shaft bearing..

the kit is here..

http://tunersmotorsports.com/?page_id=103

Has anyone installed it or know if it is any good?

My old 986 Boxster had an upgraded IMS bearing installed when I bought the car, and I thought it was a worthwhile thing to do.. But was told the 987 needed an engine teardown to replace the bearing.. This kit seems to just feed engine oil into the bearing, which from what I have read would solve the problems with failure.. But really.. should this kit do the trick?

We do not use them, but simply remove the rear seal on the OEM bearing. We have more than a few customers running this way with no issues.

So you take off the rear cover with the 3 bolts (obviously once the transmission and flywheel is out of the way), then hook the seal out of the bearing and put the cover back on? Or do you have to take the engine apart to do that?

A little more complicated: you need to prep the engine as though you were pulling the IMS (engine locked at TDC, Cams locked down, tensioners removed), then the cover comes off and a pick is used to pull the rear seal.

So the ims failure isn't a hoax to sell solutions ? I've been wondering since my 01 Boxster has been doing just fine with 63k on it. But I've always done yearly oil changes.

This is a serious question. Do that many fail ? Or just a few without knowing the service history of the car.

Depending upon the IMS design (there were three styles used, all of which are known to fail), the failure rate is between 1% and 8%, with the single row bearings (used 2001-2005) being the biggest offenders.  The biggest issue here is that they typically fail catastrophically and without warning, taking the engine with them, which is why the aftermarket replacement as a preemptive fix has developed.

Thanks JFP. But having to remove the muffler and tranny to get at it, hmmm, very expensive. Those are pretty low odds. I almost wish I needed to do the clutch so I'd have a reason. Guess I'll keep crossing my fingers.

Another alternative is to install one of the Guardian alert systems to warn you if it starts to go south.

I have owned a 987-1 from new (June 2005 delivery) . Can you please provide a link to the Guardian warning system JP?

Thanks!

      I have a 2007 C2S manual with about 132K on the odometer.  A low oil pressure light has started to show up at idle after the car is warmed up.  It seems as if the light is gradually coming on more frequently.  The pressure gage on the dash reads around 0.5 bar when the light comes on.  When the car is cold the starting pressure is around five bar and is about 3 bar at 3000rpm.  As it warms up the pressure drops to about 2 bar at 3000rpm.  I always run 0-40W Mobil 1 and change the oil every 5K miles.  With the engine off and turning the key one click the pressure gage rises to about 0.1-0.2 bar.
       
      Can anyone help me diagnose this issue?  Would be a sensor or something mechanical?

      Hi guys.Finnally got the Boxster on the road after an enforced year stood.It sounded a bit rattly when I started it up.I have done about 50 miles in it since all short journeys, and it still making the same noise.Not knowing much about these engines not sure if it's something more serious than tapped, alternator bearing???.Im not driving it and will get it recovered to an Indy for assessment, so any suggestions will be gratefully received. Hopefully other club members will chime in.

      Several people have told me that the 996 Dual Sender Oil Pressure Switch/Sensor will directly replace the 987-1 Oil Pressure Switch. Can you please confirm this and provide the part number. I would guess it is 996-606-203-03 but, I would like to be sure.
       
      Additionally, if I am running an AIM dash, should I run the pressure lead to the switch input on the ECU and get the pressure data from the CAN bus or, just leave the switch lead attached and run the pressure lead straight to an analog I/O on the AIM dash.
       
      Thanks, Tim

      Hey everyone, i own a 2010 porsche Boxter 2.9L with the PDK transmission.. yesterday after leaving the car for a 4 days i started it and went for a drive.. when i turned it on again, i got a warning message “emergency transmission run” and the car became very jerky through gearshifts and wouldnt accelerate properly.. after turning it on and off the message went away and it drove just fine but then it kept re-appearing mid drives and becomes very jerky and clunky...ive noticed since i had the car that the gearbox was sometimes clunky or would make a noise when changing gear but the dealership said that was fine and normal since its a PDK, the car is at 59,000km so its time for a transmission fluid change... could this be a low voltage problem, or transmission fluid? The reverse gear works just fine.. has this happened to any other owners?

      I am starting to prepare my car for a track day at Chuckwalla valley raceway at the end of the month, and I was told that the car as it sits has oiling issues?  My car is a 2003 Carrera.  I bought the car last year with 74k miles and immediately did the following:  LN IMS bearing, Waterpump, coil packs, spark plugs, all filters and fluids, clutch + flywheel and a stock AOS. In anticipation of the event, I am going to do an oil change from M1 0w-40 to the Joe Gibbs dt40 oil suggested by Jake Raby along with fresh filters.  Is there anything else I need to do to not have oil starvation?  Is this issue blown out of proportion?  does the 2qt sump extension make that much of a difference? will it affect the streetability?  I am running 200tw tires.
