Do the engines on the 2004 Boxsters still use the inferior IMS bearing?

I thought I read somewhere that it was improved upon by Porsche. I hope/wish? so.

I have an 04 996 engine that was a remanufactured replacement built in 06 that has a single bearing.

mike

The bearings are also ceramic -- so should be able to withstand higher heat and won't break down if the grease fails.

You should be able to combine the RMS, Clutch and IMS Retrofit for considerably less than a dealer would charge for the clutch alone at an independent shop

Mike

Just had the IMS Bearing failure at idle, hope I caught it before it caused further damage.

What are the replacement bearing options other than LN Engineering retrofit that is looking very attractive?

2002 Boxster S with 44K miles

Can't believe that Porsche would design such a poor feature!

None that I am aware of -- just performed a retrofit last night.

Problem is -- did you do any other damage?

Hi

I´m going to service the clutch, and was wondering to check the IMS/RMS issues at the same time.

Which IMS version (the bearing) do I have.

The engine number is M97/01 68702641 (the 5th digit can be "G" as well, difficult to say). So, when is the engine built?

Thanks

The best thing to do is look at it --

From Charles at LNEngineering a Deep inset flange is a single row, a shallower flange is a dual row.

This is supposed to be a single row -- I have not confirmed will do so soon

2004 996 3.6L

This is supposed to be a dual row -- I have not confirmed this one yet either.

1999 996 3.4L

This is what happens when it fails.

1999 2.5L 986

When all is said and done, I'd be interested to hear how it went for you. Also, not to discourage you but Porsche installed that "new" RMS on my '03 and 2 years later, I'm having signs of a leak again :(

Are you going to do an IMS retrofit while you are in there?

yes you have to drain the oil -- don't think you need to mess with tranny fluid.

to the uninformed -- it probably does, to the informed it is more valuable -- but we wouldn't pay for it :-) just makes it more likely to be sold.

jmho,

:welcome:

Could be as simple as a bad sensor (on the bottom of the coolant tank.

Check coolant level -- open bleed valve see if there is air in the lines?

Check thermostat is opening properly (pull it and test it on the stove with a thermostat)

Check the water pump? They are only good for 60K miles and some die at 30K.

Are the fans coming on? Clean off/out radiator grill....

do not run overheating -- could lead to blown headgasket or equivalent.

I made a catch can type set up with my AOS system trying to stop oil from entering the intake manifold. I blocked the intake hole with siliconed "Cap" that fit tightly over the intake. Then attached a catch bottle on the side of the frame behind the engine bay. From the AOS I placed a tube that fits into the catch bottle and vented the top of the bottle so that air can escape but not oil. I am hoping that this will stop my oil blow out on hard left and right hand turns at the track..

Has anyone else tried this? :renntech:

Can you post a picture?

I was trying to help a guy locally that had the same issue. We were going to install a Porsche Motorsports AOS, which is what I did on my 2004, and that solved the problem on my car.

But when I got into the engine bay, I realized his year car did not have the same configuration. At some point, it looks like Porsche changed how the AOS is mounted - on my car, it is mounted on the bottom, with the bolts through the base. On my friend's older model, it is mounted with bolts through the side, so the motorsports AOS wouldn't fit. Not sure what model year was the first to change.

We have been thinking about going the catch can route.

So you left the AOS in place with the hose still going to cylinder 4, but disconnected where it goes into the throttle body and routed that to a catch can?

We were not sure what effect a catch can would have on the vacuum, and where thinking about a sealed can and still have a connection to the throttle body, but configured so the oil is trapped.

Really interested in what you've done.

What is the "state" of the oil returning back to the throttle body?

could a catch can in series that was physically lower than the throttle body. Say it entered at the catch can at bottom, and came out the top.

therefor gravity would help capture, yet all vacuums etc would work, as well as it would start smoking again

when the catch can was "full".

Time Units (explained elsewhere many times.

Thanks -- I must have to play with my setup -- I was not having much success beyond seeing the parts.

unfortunately I just changed to a 64 bit OS and

PET won't install.....

Hopefully I can get it working properly on my old laptop.

Try Porschelibrarian, a member here.

Well I have a 2008 price sheet and the PET system -- but was unable to find the labor times there.....

Anyone have an example of exactly where to look?

thanks,

These seem like a pretty common part that I would not have to source a Porsche part for $26 a pop.

Does anyone know if there is an alternative to OEM?

thanks,

Mike

Is there someplace I can find the list of estimates for service repairs? mostly interested in 996/986 engine oriented,

thanks,

M

All 2005's failed engines I have heard of were replaced (even if they were out of warranty) by Porsche. Like RFM said... I wouldn't worry.. You will get a new engine.

Lesson to be learned here... Don't ever be out of warranty with a Porsche!!!!!! Pay the money and get the warranty. You will get two years with the new engine (but only on the engine I believe..) Extend it to at least 4 years...

Ask me how I know and I will tell a very sad tale....... :angry:

Don't have my cheat sheet handy -- did they change over engines in '05 from the '04s?

thanks,

m

Dennis,

Does your car leaks oil, especially at the RMS?

My friend just bought a 01 C2 and it has 57K mile. We saw a little oil leakage line between the engine and transmission. We believe it comes from the RMS. Should we have it repair or keep driving the car but pay very close attention to the oil level?

I would consider looking into the source of the leak -- if it is RMS it is dripping right across the IMS which is not good, and if it is the IMS, that is even worse.

How's the clutch at 57k?

If you think it might be time for a new clutch you could fix the RMS, and do an IMS retrofit for not much more than just doing the clutch.

Woah -- easy folks....

Not everyone knows automotive acronyms --

Hats off to even attempting to work on your own Porsche....

My understanding (after just recently asking on this forum)

is that you can get most of the functionality by just plugging the headlamps into the existing connectors and go..

BTW, you outbid me on that lamp :-)

mike

It might be possible, but you would have to remove the head to line bore it. And the diameter of the bore cannot be made larger so I think it would be very difficult. What year is yours (i.e. a 3,4 or a 3.6). Also what side 1-3/drivers or 4-6/passanger? If it is a 4-6 on a 3.4 there are lots of used heads available, if it is 1-3 they are much harder to find as this is the side that cracks.

Drivers side part # 1046377r -- engine has <5k miles 3.6L 2004.

mike

The cam covers are different from the 3.4's to the 3.6. Also, you can't just replace the cover, the cover and the head are paired sets as the two are line bored for the cams. The covers act as half of the bearing journals for the cams. At least this is true for a 3.4, I think also for a 3.6.

IS it possible to get the new valve cover machines to match the bore of the previous one?

Seems crazy to replace the whole cylinder head for a crack in the cam cover..... (the crack is physical and beyond welding, it got whacked by a suspension piece)

m

need to replace a valve cover on my 04 3.6L engine (drivers side if it matters)

but I have only been able to find one from a '99.

thankx,

M

Thanks for the clarification -- I may just plug and play for a while until I find the control box and time for the real install.

Will still be better than the regular lamps in there now (and look better too!)

mike

mike here is a link to a writeup on Litronic install,

http://www.realtime.net/~rentner/Porsche/L...s_Starting.html

I installed a set on a 1997. They work without any speacial wiring. However if you want to have them rotate up with high beam you must install the control box.

Porsche has a tech bulletin that explains it all.

I'm a little confused -- so If I just plug in the lights as they are -- they will work just fine -- just no auto adjust?

If that is the case it is literally a one for one swap with no rewiring?

thanks,

Mike

I am very interested in owning a 996 given that the 99 model can be had for under 20k.

However, the IMS is a big concern for me and a deal breaker. Given that said, what are ways to prevent it from happening? I really want to stay away from a 15k engine swap.

Any experience with the LN engineering IMS upgrade? How much does a tech charge to install this? Does this work? I am looking into getting a 99 with 80k miles. Can I expect to squeeze another 80k from the engine with a IMS upgrade? Thanks

http://www.lnengineering.com/ims.html

Where are you located -- I have a complete upgrade in my rebuilt '00S Boxster (he has a picture of mine installed on his website)

and I plan to do 4 retrofits over the next month. 3 in 996 engines, and one in my replacement engine

for the IMS that went in a '99 2.5L I just bought.

After getting some experience with the process, I plan to offer the upgrades and a clutch install for less than what a dealer would charge for just the clutch.

Model and year of your car please?

I am replacing the headlights of an '00S but keeping them litronic

-- looking to put them in a 99 Base.

Long story short, insurance is replacing the lamps of my '00S -- but the slight

imperfections are such that

I might consider putting them in my '99 but would need the electrics

mike

I've got a pair of Xeon headlamps -- looking for the rest of the electrics to make the swap...

what is the minimum I need and where do I find it a reasonable cost?

thanks,

mike

Where to find the serial # on the engine?

m

Wow I like the "glitter" on the oil filter :lol:

Might have to shellac that and hang it from the Xmas tree :rolleyes:

I can't wait to see what that inside of the engine looks like.
