Anothe IMS save

[harryrcb]

Last week I did an 02 Boxster S, one of my cars for resale. did not have any signs of oil leakage or fragments in the oil filter but the cam deviation was out of spec. When I got the bearing out it was definitely bad. there was axial play that did not belong. After replacement, the cam deviations for both banks were dead on 0.00 Now it runs so much smoother than before and I have more confidence that the engine is healthy.
Just another day at the office.

Hi harry...I'm in the market for a 986 S with the IMS fix: can you point me to a listing for yours?

How did the car drive with the cam deviation compared to after correction?

Well done! One question: were you using the ever-popular "Durametric Software" to take the readings or something else?
Thanks!

Is the durametric deviation read out limited to certain years. That sure would be a greg preventive maintenance tool on my 01S.

Sorry I do not have it listed yet, I want to go over the entire car before listing it will come up on my web site as soon as that is all done and i will let everyone know when that is ready. the web site is under construction but is available at boxsterbarn.com

the engine seemed to have some hesitation and a small amount of chain noise before the Ims change. It's actually hard to describe but you know what it's like when you are listening for any signs you hear and feel more things that you normally wouldn't. After the IMS install the engine reved briskly and you could feel more power.

Yes Durametric Software, next best thing to the Porsche piwis

you can read the deviations for all the years and the actual cam degree values as well and you are right that it can be a good tool for preventative maintenance

Harrycb,
Few questions:

You said the cam deviation was dead on 0 after the change. What was it prior to the change and if it was it steady at the deviated level or wavering?. Reason I ask is Durametric is reading mine as -4.22 on Camshaft position 1 and -6.11 on position 2 and they are both steady. I read that as long as they are steady it should be fine and need not be 0.

Did you replace with Porsche IMS or LN ones?

What made you pull out and look at the IMS even though there weren't any symptoms?

Thanks.

Have you had the opportunity yet to replace an IMS on a 06-08 987?
Just wondered how many more hours were involved in yanking the motor and splitting the cases to replace the IMS.

Mike, you are looking at a cost approaching a total rebuild. It really makes no sense to reuse several components once you have gone that far, so you may as well strip it down entirely and re-ring and bearing it while you are in there. The bearing and shaft end up being a minor part of the entire job……..

[MikenOH]

JFP--that's what I was afraid of; depending on how far you want to go, assuming the bore is OK, we're talking tensioners, rod bolts, IMS, oil pump, lifters, clutch and more-- a lot of money $10-15K? That is a very difficult call for me to make if it were to happen.
I can just see me having that discussion with the wife saying "well, I found some metal in the filter and we need to do some preventative work to save the block--about $15K worth prevention". I don't know if I'm that good of a salesman.

Harryrcb,

You're 420 miles from me. When I'm ready for the IMS fix, I'll be coming down to see you...

Harry, you are a credit to your profession in that you sound like you know what u are doing. I live many miles away in Canada but if I lived closer you would be the first person I would come to to get my Boxster fixed. Keep up the good work!

Because "splitting the cases" typically requires pulling pistons out of their bores, you run the risk of the engine not resealing if it has some miles on it. So you would be into rings, bearings, a re-hone at a minimum, plus all the other do dads you already mentioned. Unless you are going to do this your self, and you have the tooling required, you are going to have to pay for a rebuild by an outside shop. You should also go through the heads while you have it apart; new cam followers, retainers, oil seals, threaded replacements for the failure prone press in coolant plugs, perhaps springs, etc. etc. By the time you are done, you will be north of $10K, with how far north depending upon how many improvements and options you throw in.

You cannot realistically just take the engine apart, put in a new IMS shaft, and throw it back together again and expect it to be pristine; it won’t be……..

Don't have the exact numbers in front of me. Not in the office, at the moment. But they were not 0 and to answer your second question no they do not need to be 0 as a matter of fact it's rare that they are. I pulled the IMS as I intend to sell this car and that is everyone's concer and rightfully so. Yes I used the LN Engineering bearing, they come serialized with a barcode sticker that I place on the door. and engine

Sorry I took so long to get back with all of you JFP answered this.
