  1. Thanks all. Car appears to be running fine right now. Think I will keep driving it gently and monitor how things go, then change back out to some 5W 40 after 2k KMs. I will do a UOA - just hope that blackstone will send their kits overseas.
  2. Well! I dodged a bullet. I couldn't bear watching my ride sitting sick like that in the carpark. I didn't want to wait any longer for my indy , as I was getting the feeling he was losing interest in further troubleshooting my problem. So on Monday I had it towed back to the dealer. Porsche HK charged $200 (USD) for diagnosis, i.e. to find out the cause of the red "engine oil pressure too low" warning light. I didn't want to risk driving it further. 1st fix - oil pressure sensor / sending unit. Dealer test drove the car and couldn't hear any tapping or knockin
  3. Thanks DBJoe. Good that you point out the potential problem with the sending units. Another thing that I can hope the problem to be! I was wondering also if the two sending unit wires were reversed, what would happen? I understand the smaller terminal should be connected to the low pressure warning light, and the big terminal to the gauge. Just thinking...... One other thing, I read somewhere about the oil pump hex key drive wearing out on some 996s, although rare. This introduces play on the pump gears I think, and could cause the pump to fail. Well let's hope my probl
  4. Thanks for the welcome and comments! Oil Pressure Relief Valve - unfortunately I've had this replaced already. It didn't make any difference. This was the most recent thing I had done to the car. I put in the new spring, plug seal and the updated 997. piston. My indy said my old spring was slightly shorter than the new one, but otherwise it wasn't damaged. I was really hoping this would solve it but it didn't. I'm not really losing coolant. I can smell a little whiff of coolant when I put my nose near the rear wheel / engine bay area after a drive. But it hasn'
  5. Hi all I have a low oil pressure problem on my 2003 996 C4S RHD / ROW, Tiptronic. Owned since 2012, oil change at least annually first with Mobil 0W40, more recently Fuchs or Liqui Moly (green) 5W/40. Looking for help from anyone who has seen something similar - I've looked at various threads on this topic but couldn't find the exact symptoms. Last oil change was done in Sept 2018 with the Liqui Moly green. About two months later, the "oil pressure too low" red light started to come on intermittently. Either on start-up, or sometimes when slowing down or waiting a
