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!

      Recently I had been noticing issues with my cooling system the coolant temp guage would go past the 0 on 180 and I wouldn’t hear fans or anything. (Already tested fans and resistors and relays).   The temperature Will continue to creep up if I sit still, with no signs of fans, AC OFF.

      I replaced the coolant temp sensor. Problem fixed!! Then same issue again it seems after a week of driving.  

      Now i currently have ordered another temp sensor just Incase I maybe did something to cause the other new one too fail, I’ll be changing it again today.

      However I was doing the climate control hack to check my actual temperatures today while doing a short troubleshooting drive. And I noticed my oil temperature said 0, which is physically impossible 🙄


      Is it possible the oil temp guage is throwing off the coolant sensor?    Is it even possible for the oil temp sensor too go bad but not the oil level sensor? (They are a 2 in 1 sensor)   

      THANK YOU IN ADVANCE

      Hi all, just purchased a 1961 notchback 1600s, I have never drove a Porsche until the day I purchased this car, got the bug now and i love Porsches more than ever now, the car is in very good shape, but i want to change all the fluids, grease all the parts, and do all the maintenance there is, the oil was so dark when I checked the level and it was all the way to max line of the stick, i would appreciate if you guys can tell me where to buy all the maintenance parts, and where can I buy the shop manual, and what are the things I should do, there is a small leak on the floor from engine very small, but a palm size of oil from transmission on the ground,  thanks guys cheers😁

      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?
