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

WATERPUMP!

Thank god. I was really wanting to replace it anyways being 13 years old and 46k miles. This gets it done. They gave me a rather high quote for IMS (2000-2500) so I need to shop around for that - I still want that done for peace of mind.

How much did they quote for the IMSB replacement?

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.

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.
