What's this oil leak - RMS/IMS? 997.1, please help identify
Discussion
Hi
The big bolt is the timing chain tensioner. The crush washer commonly corrodes and leaks.
Washer costs pennies but about hours labour or so to lock engine before removing the tensioner and changing washer.
We had it done at Porsche during a service.
From your pic it seems to be coming I from there. A bit worrying that it wasn't rectified at the recent service. Was car serviced at porsche dealer or specialist?

Looks like leak is coming from the hexagon plug in picture one . This is the cam chain tensioner plug. The aluminium sealing washer under the head of the plug errodes with water/salt from road and allows oil leak . The washer is approx £2 from Opc , oil needs to be drained and crankshaft locked in a safe position to allow removal of plug to replace washer. Do both cylinder bank plugs at same time . Did both mine on 996 every second year ( because of poor quality of rings ) during service whilst oil being changed as cheap to do then. Regards.
If pic two is at 6 o'clock on engine case it could be rms or intermediate shaft seal . The oil stain looks to be pretty high up crankcase though so could even be spark plug tube seal weeping and oil running down casing to low point. My 996 had this and leak source was only seen when car on ramp. Regards.

Yes the exact place of RMS.Interestingly there is oil in more than one place - looks like two leaks.
As I told the guy, if it's simple no problem if reflected in the price, if RMS, it's a bigger issue.
