Has RMS and Cam cover leaks been solved?

I had a 2002 C2 at 8000 miles there was a cam covers seal leak which the dealer fixed. At 10000 miles there is a RMS leak. Does anyone know if Porsche corrected these problems in the 2003 and 2004 model? Welcome any input.

One would think so although folks have reported the RMS leaks from MY 99 thru at least MY 02. Haven't heard that much about the other.

Hi, the factory tells me it's been fixed, the RMS problem with a new type PTFE-seal and the cam cover problem with a different sealant and different o-rings. I would hope they got the cam covers sealed. As for the RMS, I wouldn't bet the farm on it, because it's partly got to do with the way the crankshaft runs in a spherical graphite cast iron case which in turn sits in the aluminium crank case which houses the RMS. Aluminium and cast iron have different thermal expansion coefficients, so if the engine warms up, they can move relative to each other. Then the crank shaft and RMS are not aligned any more and you've got your oil leak. Cheers, uwe

When the RMS seal leaks how much oil are we talking about? Dime size or bigger ?

I've often wondered about that one too, though I do not whish to find out first hand: Is it a small drop or a large puddle?

RMS leak equals a few large (quarter size) drop marks on the garage floor, at least in my case. A total over a month of probably a dozen or so drops, and that translated into a new engine this week. Bob

the leak is a small puddle. about 8-10 cm in diameter

In my case it was 8-10 quarter size drops over a week or so. I'm not 100% sure of the week part, because I didn't notice it until there was already 7-8 drops.

does this problem exists on the 3.6 GT3 engine aswell?

No, the GT3, GT2, and Turbo motors are all based on the 964/993 crankcase. The M96 motor in the NA 996 is a different breed. I had several quarter sized drops on my garage floor before my RMS was diagnosed as well. Don't count on it being fixed in the newer 996s, I've heard of several MY03s with RMS leaks.

and once you get it fixed....it may go again, and again, and again. I just had mine done 6 weeks back and it's gone again. You may get a new engine. Sounds good. But what makes you think the RMS won't go on the new engine. In fact it's almost a cert! I guess we just all have to live up to this fact on the M96 engine. I have learned to think of it like a clutch. It will go eventually and I will have to pay for it.

I heard awhile back that Porsche determined it was in the basic design of the 9X6 Boxster/996 engine . They have updated the seals a few times w/o it working as a permanent fix. They realize it isn't fixable on current engine, but it's cheaper to keep replacing with redesigned seals vs redesigning the engine - you know - the " we are a small company, limited engineering resources due to the Cayenne/Cerrera GT development " line we've heard for a while. That's why a problem that showed up on Boxsters in 1998 still exists on '03 996s , 6-7 model years later . Someone at my dealership service jokes it's the Porsche- mechanic full employment act.
