Hi all,

I came across a 2006 987.1 Cayman S with 60K miles on it. The vehicle looks clean w/o any bore scoring but the PPI did reveal a leak in the rear main seal.

Any ideas how much this would cost to fix? I researched some numbers online and it says 10-12hrs of labor + seal ( $60- $100). Does this sound reasonable?

Thanks in advance for your comments.

Going through the same thing myself. Havnt gotten a quote yet. Likely wont get one for another week or 2 as im trying to do my research into the entire process but ive had a number of people tell me that its recommended to also replace the clutch while you're in there and fixing the RMS issue. Will keep you posted on a quote when i get one.

Thanks!
That would be very helpful. I'll try to look into it and share my findings as well.

I had a PPI on a 996(same engine family) conducted not too long ago with a RMS leak as well. Owner said it had been going on for a while and his plan was to take care of it when the clutch was due. PPI shop said it was a reasonable plan as it wasn't a bad leak. An option to consider/research. Clutch, RMS, and IMS normally all get taken care of at the same time.

If you have the interest the price of 10-15hrs of labour can buy you a lot of tools or part of a hoist/lift.

This^^^ Definitely replace the clutch and IMSB while you’re in there 👌

Good idea about replacing the clutch and IMS. Trying to figure out if its worth the additional expense. The seller isn't willing to budge from the $28K price. Add in the additional expense to fix then I'm in the mid 30s for a 60K 987.1 Cayman S.

How are you guys planning to replace the IMSB without a complete engine tear down which will cost you $15k. Do you mean remove the outer seal? That’s the only thing you can do on a 987.1 with just the trans removed, which is what you do to address the RMS and clutch.

I believe you can remove the bearing seal(s) that will allow more of an oil bath as well as the cover seal could be replaced. Recently Hartech has announced some sort of a new cover that will feed that bearing pressurized oil. I don't know much about that product. I have a .2 so I am not very familiar with what can be done.

Tear the motor down? Who told you that? Remove the gearbox, pull out the clutch and flywheel, remove the IMSB flange cover, lock to TDC, pull out the IMSB…

please educate yourself on the differences in IMSB and case design between the 986 and 987 generation, otherwise you’re just spreading misinformation.
The 987 has a larger diameter single row bearing, which unlike the smaller bearings found in the 986, can not be extracted through the case. Only way to remove it is from the inside of the engine, which requires a complete tear down.
The only service you can do from the outside of the case on a 987 bearing, with the trans dropped, is remove the outer oil seal so the bearing sits in an oil bath instead of being sealed.

BondJ

You are quite correct and I apologise. The bearing we replaced years ago on my mates 987 was an early model

no worries. No 987 Cayman came with the smaller serviceable bearing. All of them had the larger single row. The only variation for “early model” applies to the 997 Carrera and 2005 987 Boxster with the 3.2 liter (never available in Cayman).

BondJ

Yep. He was running an early 987 Boxster👍

Thanks for all the comments, folks.

I'm going to pass on this car.

The dealer wasn't budging on the price. It needed new tires and had a type 6 over-rev in addition to the leaks.

I see you already said pass on the deal but in case you still wanted to keep track of cost. Screenshot of my bill from 2019 when I went to my indi for Clutch, flywheel, and seal. Mainly my throw out/release bearing was on its way out and everything else had just enough wear on it to replace it all together while the car was on the lift. good luck on your search Apologies for any weird formatting.
