Engine noise/grind/rattle - Should I have it towed?

pheww.... ya dodge a bullet. Welcome to Porsche world.

that quote does seem high. I'd be curious to see how many hours they're claiming.
I got a break because...I forget why...but I don't think its more than a 10 hour job, probably less for someone whose done many.
Parts are another $700? Maybe they were throwing in the new flywheel ($600-700?) ...although with your mileage I doubt its scored/burnt. That being said, it would be hard to quote without knowing if you have a single or dual row, something they can only do once they're in there. If it is a single row, it will cost more. So I assume they'd be using the new IMS Solution vs. the old single row upgrade that would have needed to be replaced a few times over the life of the engine. But stock of those old single row upgraded bearings will probably be history soon. So those who did a single row upgrade will need to swap over to the solution at some point before or at the next clutch change.

whoever does your IMS ask how many they've done before. One reason LN will not be selling direct to customers anymore is because of installers not following directions properly. My mechanic who fixes all vintage of Porsche and other makes stressed that one needs to be very careful when doing this job.

In my area - SF Bay, the price to replace the IMSB is about $1800 ($1000 labor and $800 parts and supplies). If you add a new clutch ($500) and new flywheel ($700) to the job, the price is in the low $3000.

If you do decide to replace the IMSB, then look at the thread below. The general recommendation seems to be to install the IMSB without the outer seal so 'splash' oil lubricates the bearings. I take it that this advice applies whether you install a stock, Pelican Parts or LN Engineering bearing. The LN Engineering ceramic bearing is the best choice for longevity.

Stay away from Eurocar-werk for the IMS job.

Thanks for the tip - they were next on my list to get a quote from.

I got another quote for $1850 from a highly reputable shop (Mike Callas). Not sure what IMS solution he uses though, need to talk to him again.

Mike is one of the best. At his age, I'm not sure if he actually does the work but I'm sure he's got a very experienced team of mechanics. His reputation is well known.

Unless things have changed in the last 10 days, the IMS Solution is only available for installation at Flat6Innovations.

Sometime down the road, it's unclear at the moment when, the IMS Solution will be made available for sale to dealers and independent shops. As I understand it, the Solution will not be sold directly to the DIY folks.

While the price of the IMS Solution to dealers isn't clear yet, it's likely to be around $1500 compared to roughly $650 for the IMS Retrofit.

In my mind, the IMS Solution is clearly the best option because the engine will not self destruct if it should ever fails. I also think the Retrofit is a great product because I believe the odds of it failing are extremely small.

That said, if it were clear when the Solution could be bought and installed by shops other than Flat6Innovations, you'd have a much easier time deciding whether to wait for it to come available or install the LN IMS Retrofit beforehand.

NICE. Glad to hear it.

The OP has a 2000 S. It's a dual row. The "final solution" as it's called, , is not offered for that car.

have the shop give you the old water pump and give it a good look. if the plastic impellers on the pump are missing any chunks (from a bad bearing in the pump allowing the impeller to smack against internal engine walls) then these pieces are throughout your engine and will need to be cleaned out lest they block important coolant passages.

Mine did the same thing, then left me stranded 40 miles from home, easy fix though. Good Luck!

[patssle]

Got the car back, so far so good.

They put down 7 hours for water pump replacement - what do you guys think? First time using that shop so I'd like to know how that compares. That includes coolant flush and diagnostic (plus checking the oil filter, checking noise with scope from IMS after repair).

I'll post a picture of the pump blades this evening.

Sounds pretty high. I did mine and I'm not the fastest wrench and it took me around 4 hours, including doing the engine mount.

[thom4782]

My labor estimating guide says 5.2 hours (3.7 for a warranty repair). Pretty pricey little job.

Did mine solo in the driveway in 5.5 hrs last year. That includes flushing the radiators and engine to try and get as much of the plastic debris from the broken impeller out. I would think that a shop with a lift and experienced personnel could do it much faster.
