Should I replace my rear seal while my flywheel is off for the clutch replacement? My tech says it's cheap and easy to do now. It's not leaking, but car has 53K miles on it.

IMO, no. I have no read of anyone with a 997.2 with a leaky rear main seal. My 2009 C2S has 124K miles and not a drop on my floor. These are not the same engines as the series of the prior 10 years.

Save your money.

May not be necessary, but I would do it while you are there. Whats it cost? $50 with labor?

shekmark

He said it's a $30 part and maybe 1/2 hour labor

It's interesting that they tell you 1/2 of labor. Realistically the tech should be able to do it in 5-10 minutes. It's one of those "since you're in there jobs" that will make you feel better and the tech a few extra bucks.

The crankshaft in the 997.2 Direct Injection engine does not use a separate crank carrier yoke so the chances of runout/ eccentricity of the crank end in the rear Main Seal which often caused problems in the 996 and 997.1 engines does NOT occur in the 997.2 engine.

Having said that I changed my RMS when I replaced the clutch on the basis of minimum cost ! So...up tp you!

I agree with Bruce; however, sabotaging the seal would be very easy and you could get a "we told you so" later. I would do it

Stressing over something that costs $50 and is recommended by the guy you chose to work on your car . . .Just because someone on here who may or may not have a lot of Porsche experience has not read about it failing or needing to be replaced on here does not mean it never happens or is not a potential issue. I doubt most people on here would take the time to post about issues with a $30 part. If you are second guessing you tech, get a new tech.

I get it and throughout the years I have tried to save a few dollars here and there by using Indies. Back in the very early 1990s (90, 91 or 92), I used one guy that was supposed to be respected and great with BMW and Porsches. Turned out he had a cocaine problem and liked charging for work he never did.

At the end of the day, I like high performance cars and I have learned to maintain my cars with an open check book and only have people I trust working on my cars which are, gasp, dealers when it comes to mechanical issues. I also do not get cheap when it comes to reasonable repairs or while we are in there recommendations over the years. A lot of guys on here may be dealing with their first Porsche or first high end sports car and have a different mentality. I focus on more on keeping my cars in tip top shape rather than saving a few dollars here or there and rolling the dice.

Over the years, I have saved more money by using dealers as I cannot tell you how many times I have had very expensive stuff covered by goodwill that those using Indies will never get covered. I also usually get 20% discounts which you too could get if you were loyal to your local dealerships and got services there.

Look, I too can work on my cars and have built many 911 races cars myself back in the air cooled days. Just not worth it to me these days and I trust those working on my cars to recognize and address problems before they become serious more expensive problems later.
