Got the car, I'm the process took a while so we're on the road late, but everything is good so far! Image Unavailable, Please Login
Oil pressure seems a bit low, can't tell if the gauge and circuit are just old? Its around 5 or 10 at idle and goes up to approx 40 around 2000 and stays there from 2000 rpm up. Is that what the oil pressure relief valve is set at? I'd love to get a modern gauge on the oil pressure when we get home for a more precise reading There's no engine or valve noise or anything else I'd associate with low pressure and it's running very smooth and solid.

Just read some info and people say the gauge is notoriously inaccurate which makes sense. We are seeing the tach bounce every once in a while and drop to zero and for a little bit read half the actual rpm, which I assume because the ignition runs 2 banks of 4 cylinders and one was probably loose and dropping out. Drive is great otherwise! It does feel like the heater is on all of the time, but you guys warned us about that
Congrats on picking up your 308! That is typical behavior for the sender. If you want the oil pressure gauge to read correctly...you need this https://www.ferrarichat.com/forum/threads/modern-oil-pressure-sensor-kit-for-3x8-mondial-etc.567312/
Had a smooth ride first day. A little too hot in the car and way more traffic than I would have liked coming out of Portland but we got through it and into the nice open highway. Engine feels like it's running great. Got as far as Medford Oregon. The woman at the front desk of the hotel offered us a special parking spot where they would be able to keep an eye on the car. Everyone we see loves it. Had my first Magnum pI reference today. "Hey. That's the one from Magnum PI right? It's beautiful!". Image Unavailable, Please Login
Re the oil pressure - the gauge indication is too low above 4000 RPM IF the gauge is correct. As noted, it may not be and can easily be checked with a manual gauge. It's probably the gauge/sender but needs to be checked. The gauge MIGHT be accurate within itself - although the indications are wrong, the needle may move in proper relation to pressure. In any case I wouldn't take the RPM past 5K until the oil pressure is checked and verified that it is within spec. As far as the gauge reading, of course it would be good to have it correctly display pressure but if the needle moves in correct relation with actual pressure, you could just "know" that and not worry about what it shows. I wouldn't buy anything at the moment other than a manual oil pressure test gauge/kit if you don't already have one. Once you have determined the actual oil pressure you can proceed with whatever steps you think appropriate.
