blade7Hot oil pressure on my original gauge is 3 bar, I've used Millers 15/50 CFS for around 20k miles, changed every 3k miles. And the car has done 103k miles. Does your engine builder have an accurate oil pressure gauge, if not I'd probably buy/borrow another one.
blade7Forgot to mention, my gauge shows 5 bar from cold and for a few minutes until the oil starts to warm up. I think it reads zero until the engine is started too, I've just charged the battery, I'll reconnect it and check that. Is there a warning buzzer for low oil pressure on 944 engines? My old 85 Scirocco GTX had one.
blade7 I've used Ester blend synthetic oil for over 12 years. It's nearly twice the price of the Quartz oil, but if the oil pressure does turn out to be a bit low, I'd use a higher spec oil.

Yeah, possibly the oil, but it's always held good pressure before. Thinking back, the pressure was about the same pre-rebuild, and I put that down to the engine being ****ed. Wind forward and I am using the same OPRV and sender, and have same readings. I have a hunch either the sender is faulty or the OPRV needs cleaned (Simon sgl1966 says he had a similar issue on a fresh build, and cleaning the OPRV cured it). I've purchased some OPRV o-rings and a new sender, not the cheapo brass coloured one that you see everywhere, gone for an FAE 14990 from ECP, £36, at least it is silver and the terminals look more substantial than my current one (the cheapo brass effort!). So, I will be armed with these goodies when we get the proper gauge on and see where we are. OPRV could have got a but gummed up while my engine was disintegrating or when bedding in new rings, either way, bar a wiring issue, it surely must be the sender or the OPRV. All will be revealed soon! Stuart
