Thanks for the replies guys.
Pedro, if I do go ahead and get it looked at would you recommend fitting the retrofit IMS bearing at the same time or just to inspect it and possibly change the IMS seal? I don't think it's leaking too bad at the minute but I will be monitoring like a Hawk from now.
Marc it's interesting where you say it may be oil from above the RMS and that's got me thinking. When the RMS seal leaks would oil come out from the bottom of the join where the gearbox and engine meet or could it come out from above?
And just thinking out loud here, but as this is the centre of the engine wouldn't spark plug leaks be on the outside edges of the engine as opposed to the centre of the engine? Not sure what the AOS looks like. In fact before just Goggling it I didn't even know what an AOS it was
I was thinking about cleaning the area and then looking to see if I can see where the oil comes from after that. Does that sound like a good idea or do you think that may wash away the evidence and if I look properly as it is currently it should be more obvious?
Thx

Can you believe this, one Porsche specialist I spoke with in the UK today said that they can change the seals (RMS & IMS seal) but if the IMS bearing has play in it they will tell you that you have had it and recommend a rebuild. They don't fit the retro kit! And they have been running for many years. I was shocked and didn't know what to say to them.
Others recommend living with the oil leak until it gets bad. I wonder if fitting a magnetic sump plug and changing the oil every 3/6 months (and seriously checking the oil filter at changes) is a sane option? Thoughts anyone... This does feel like Russian roulette though.
And one specialist say that they use 5w/40 or 10w/60 oil as it leaks less. This doesn't make much sense to me. Does anyone know if this is the case?
How can I tell if the oil I use is a group 5 with ester? *NM* Naples986 - Monday, 12 March, 2012, at 9:58:07 pm |

Marc, you said something I've never heard before and maybe I've over-analyzed this but here goes. You said, "My info is group 5 oils are ester based oils and one characteristic of an ester based oil (besides that they are usually a very good oil), is that ester based oils tend to cause some seals/gaskets to swell slightly and in doing so can fix a mild seal/gasket seep." My understanding is that the OEM Porsche-sealed IMS tends to fail (if at all) by oil and unburned gas penetrating the seal and diluting the grease inside the bearing and eventually the bearing lacks sufficient lubrication and fails. If so, use of an ester-based oil would also tend to swell the seal slightly on the OEM IMS. Would this not therefore help preserve the IMS seal and therefore the integrity of the bearing, at least as long as one never switched from the Group 5 oil?
BTW, how would I identify a Group 5 oil to use in my car?
Without coming down too hard on your theory I want to point out that swelling the seals of the ... MarcW - Wednesday, 14 March, 2012, at 1:31:23 pm |
Are there any additives which can help condition the rubber seals and prevent leaks? *NM* Naples986 - Friday, 9 March, 2012, at 3:59:53 pm |
